+# Plan for Adding Overture Maps Support to Basemap.java
+
+This document outlines how to expand Basemap.java to accept Overture Maps data from Geoparquet files as an alternative to OSM input.
+
+## Overview
+
+Add `--overture` argument to accept Overture Maps Geoparquet data as an alternative to `--area` (OSM data). These options are mutually exclusive.
+
+## Overture Data Structure
+
+Overture Maps data is organized in Hive-partitioned Geoparquet files:
+```
+theme=buildings/type=building/*.parquet
+theme=buildings/type=building_part/*.parquet
+theme=places/type=place/*.parquet
+theme=transportation/type=segment/*.parquet
+theme=transportation/type=connector/*.parquet
+theme=base/type=water/*.parquet
+theme=base/type=land/*.parquet

+```
+
+**Note:** The base theme includes `water`, `land`, and `land_cover` types which replace the three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) used in OSM mode.
+
+## Code Changes Required
+
+### 1. Command-line Argument Handling
+
+**Location:** `Basemap.java:163-216`
+
+Add `--overture` argument accepting a directory path containing Hive-partitioned Overture data.
+
+```java
+String area = args.getString("area", "Geofabrik area name to download, or filename in data/sources/", "");
+String overtureBase = args.getString("overture", "Path to Overture Maps base directory", "");
+
+// Validate mutual exclusivity
+if (!area.isEmpty() && !overtureBase.isEmpty()) {
+  LOGGER.error("Error: Cannot specify both --area and --overture");
+  System.exit(1);
+}
+if (area.isEmpty() && overtureBase.isEmpty()) {
+  area = "monaco"; // default
+}
+```
+
+**Update help text** to document `--overture=` option.
+
+### 2. Data Source Configuration
+
+**Location:** `Basemap.java:214-222`
+
+Add multiple `.addParquetSource()` calls for different Overture themes when `--overture` is specified.
+
+```java
+if (!overtureBase.isEmpty()) {
+  Path base = Path.of(overtureBase);
+
+  // Buildings
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=buildings", "type=building", "*.parquet").find(),
+    true, // hive-partitioning
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Building parts
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=buildings", "type=building_part", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Places
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=places", "type=place", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Transportation segments (roads)
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=transportation", "type=segment", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Transportation connectors
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=transportation", "type=connector", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Water
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=base", "type=water", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Land
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=base", "type=land", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Land use
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=base", "type=land_use", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+  // Divisions (boundaries)
+  planetiler.addParquetSource("overture",
+    Glob.of(base).resolve("theme=divisions", "type=division", "*.parquet").find(),
+    true,
+    fields -> fields.get("id"),
+    fields -> fields.get("type")
+  );
+
+} else {
+  // Add OSM source (existing code)
+  planetiler.addOsmSource("osm", Path.of("data", "sources", area + ".osm.pbf"), "geofabrik:" + area);
+
+  // Add GeoPackage sources (existing code) - these are OSM-specific
+  planetiler.addGeoPackageSource("osm_water", sourcesDir.resolve("water-polygons-split-4326.gpkg"),
+    "https://osmdata.openstreetmap.de/download/water-polygons-split-3857.zip");
+  planetiler.addGeoPackageSource("osm_land", sourcesDir.resolve("land-polygons-split-4326.gpkg"),
+    "https://osmdata.openstreetmap.de/download/land-polygons-split-3857.zip");
+  planetiler.addGeoPackageSource("landcover", sourcesDir.resolve("daylight-landcover.gpkg"),
+    "https://r2-public.protomaps.com/datasets/daylight-landcover.gpkg");
+}
+```
+
+**Important:** When using `--overture`, the three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) are NOT added because Overture's base theme already includes `water`, `land`, and `land_cover` types that serve the same purpose. The handler registration for these layers will remain unchanged but they will receive data from Overture's base theme instead of the GeoPackage files.
+
+**Key points:**
+- All sources use name `"overture"` (routing is by source layer, not source name)
+- Enable Hive partitioning with `true` flag
+- ID extraction: `fields -> fields.get("id")`
+- Layer extraction: `fields -> fields.get("type")`
+- Use `Glob.of().resolve().find()` to get `List` of partitioned files
+
+### 3. Source Handler Registration
+
+**Location:** `Basemap.java:36-103` (constructor)
+
+Add `registerSourceHandler("overture", ...)` calls for each layer:
+
+```java
+if (layer.isEmpty() || layer.equals(Buildings.LAYER_NAME)) {
+  var buildings = new Buildings();
+  registerHandler(buildings);
+  registerSourceHandler("osm", buildings::processOsm);
+  registerSourceHandler("overture", buildings::processOverture); // NEW
+}
+
+if (layer.isEmpty() || layer.equals(Places.LAYER_NAME)) {
+  var place = new Places(countryCoder);
+  registerHandler(place);
+  registerSourceHandler("osm", place::processOsm);
+  registerSourceHandler("overture", place::processOverture); // NEW
+}
+
+if (layer.isEmpty() || layer.equals(Roads.LAYER_NAME)) {
+  var roads = new Roads(countryCoder);
+  registerHandler(roads);
+  registerSourceHandler("osm", roads::processOsm);
+  registerSourceHandler("overture", roads::processOverture); // NEW
+}
+
+// Water - existing registrations remain, but data source changes
+if (layer.isEmpty() || layer.equals(Water.LAYER_NAME)) {
+  var water = new Water();
+  registerHandler(water);
+  registerSourceHandler("osm", water::processOsm);
+  registerSourceHandler("osm_water", water::processPreparedOsm); // OSM GeoPackage
+  registerSourceHandler("overture", water::processOverture); // NEW - from base theme
+}
+
+// Earth - existing registrations remain, but data source changes
+if (layer.isEmpty() || layer.equals(Earth.LAYER_NAME)) {
+  var earth = new Earth();
+  registerHandler(earth);
+  registerSourceHandler("osm", earth::processOsm);
+  registerSourceHandler("osm_land", earth::processPreparedOsm); // OSM GeoPackage
+  registerSourceHandler("overture", earth::processOverture); // NEW - from base theme
+}
+
+// Landcover - existing registrations remain, but data source changes
+if (layer.isEmpty() || layer.equals(Landcover.LAYER_NAME)) {
+  var landcover = new Landcover();
+  registerHandler(landcover);
+  registerSourceHandler("landcover", landcover::processLandcover); // OSM GeoPackage
+  registerSourceHandler("overture", landcover::processOverture); // NEW - from base theme
+}
+
+// Repeat for all other layers...
+```
+
+**Note:** The existing handlers for `osm_water`, `osm_land`, and `landcover` are kept because they're only called when those GeoPackage sources are added (OSM mode). When using `--overture`, those sources aren't added, so only the new `overture` handlers will be called.
+
+### 4. Layer Processing Methods
+
+**Location:** Individual layer files (Buildings.java, Places.java, Roads.java, etc.)
+
+Add `processOverture()` methods in each layer class. Filter by `feature.getSourceLayer()` which comes from the Hive partition `type=` value.
+
+**Example for Buildings.java:**
+
+```java
+public void processOverture(SourceFeature feature, FeatureCollector features) {
+  String sourceLayer = feature.getSourceLayer();
+
+  // Filter by source layer (from Hive partition type=building or type=building_part)
+  if (!"building".equals(sourceLayer) && !"building_part".equals(sourceLayer)) {
+    return;
+  }
+
+  // Read Overture attributes
+  Double height = feature.getDouble("height");
+  String roofColor = feature.getString("roof_color");
+
+  // Extract nested names (Overture uses structured names object)
+  String primaryName = feature.getString("names", "primary");
+
+  String kind = "building_part".equals(sourceLayer) ? "building_part" : "building";
+  Integer minZoom = "building_part".equals(sourceLayer) ? 14 : 11;
+
+  features.polygon(LAYER_NAME)
+    .setId(FeatureId.create(feature))
+    .setAttr("kind", kind)
+    .setAttr("name", primaryName)
+    .setAttr("height", height)
+    .setAttr("roof_color", roofColor)
+    .setAttr("sort_rank", 400)
+    .setZoomRange(minZoom, 15);
+}
+```
+
+**Example for Places.java:**
+
+```java
+public void processOverture(SourceFeature feature, FeatureCollector features) {
+  String sourceLayer = feature.getSourceLayer();
+
+  // Filter by source layer
+  if (!"place".equals(sourceLayer)) {
+    return;
+  }
+
+  // Read Overture structured data
+  String primaryName = feature.getString("names", "primary");
+  String primaryCategory = feature.getString("categories", "primary");
+
+  // Map Overture categories to basemap place types
+  String placeType = mapOvertureCategory(primaryCategory);
+
+  features.point(LAYER_NAME)
+    .setAttr("name", primaryName)
+    .setAttr("place_type", placeType)
+    .setMinZoom(calculateMinZoom(primaryCategory));
+}
+```
+
+**Example for Water.java:**
+
+```java
+public void processOverture(SourceFeature feature, FeatureCollector features) {
+  String sourceLayer = feature.getSourceLayer();
+
+  // Filter by source layer - Overture base theme water
+  if (!"water".equals(sourceLayer)) {
+    return;
+  }
+
+  // Read Overture water attributes
+  String subtype = feature.getString("subtype"); // e.g., "lake", "river", "ocean"
+  String primaryName = feature.getString("names", "primary");
+
+  features.polygon(LAYER_NAME)
+    .setAttr("kind", subtype)
+    .setAttr("name", primaryName)
+    .setZoomRange(0, 15);
+}
+```
+
+**Example for Earth.java (land polygons):**
+
+```java
+public void processOverture(SourceFeature feature, FeatureCollector features) {
+  String sourceLayer = feature.getSourceLayer();
+
+  // Filter by source layer - Overture base theme land
+  if (!"land".equals(sourceLayer)) {
+    return;
+  }
+
+  features.polygon(LAYER_NAME)
+    .setAttr("kind", "land")
+    .setZoomRange(0, 15);
+}
+```
+
+**Example for Landcover.java:**
+
+```java
+public void processOverture(SourceFeature feature, FeatureCollector features) {
+  String sourceLayer = feature.getSourceLayer();
+
+  // Filter by source layer - Overture base theme land_cover
+  if (!"land_cover".equals(sourceLayer)) {
+    return;
+  }
+
+  // Read Overture land cover attributes
+  String subtype = feature.getString("subtype"); // e.g., "forest", "grass", "wetland"
+
+  features.polygon(LAYER_NAME)
+    .setAttr("kind", subtype)
+    .setZoomRange(calculateMinZoom(subtype), 15);
+}
+```
+
+**Key differences from OSM processing:**
+- Use `feature.getSourceLayer()` for routing, NOT tag checking
+- Source layer comes from Hive partition path (e.g., `type=building`)
+- Access nested JSON properties: `feature.getString("names", "primary")`
+- Overture uses `subtype` instead of OSM tag combinations
+- No `hasTag()` checks needed - source layer determines feature type
+
+### 5. Overture Schema Mapping
+
+Overture Maps uses a different schema than OSM:
+
+**Overture structure:**
+- `names` object with `primary`, `common`, etc. subfields
+- `addresses` object for structured address data
+- `categories` object with `primary` and `alternate` fields
+- `subtype` field for classification (instead of OSM tags)
+- Organized by theme/type in Hive partitions
+
+**Mapping examples:**
+- OSM `building=yes` → Overture `theme=buildings` + `type=building`
+- OSM `amenity=restaurant` → Overture `theme=places` + `type=place` + `categories.primary=restaurant`
+- OSM `highway=primary` → Overture `theme=transportation` + `type=segment` + `subtype=road`
+
+### 6. Output Filename
+
+**Location:** `Basemap.java:267`
+
+```java
+String outputName;
+if (!overtureBase.isEmpty()) {
+  outputName = "overture-basemap";
+} else {
+  outputName = area;
+}
+planetiler.setOutput(Path.of(outputName + ".pmtiles"));
+```
+
+## Summary of Required Files
+
+| File | Changes |
+|------|---------|
+| `Basemap.java` | Add `--overture` argument, validation, conditional `.addParquetSource()` calls, source handler registration, output filename |
+| `Buildings.java` | Add `processOverture()` method |
+| `Places.java` | Add `processOverture()` method |
+| `Roads.java` | Add `processOverture()` method |
+| `Transit.java` | Add `processOverture()` method |
+| `Water.java` | Add `processOverture()` method |
+| `Earth.java` | Add `processOverture()` method |
+| `Landuse.java` | Add `processOverture()` method |
+| `Landcover.java` | Add `processOverture()` method |
+| `Boundaries.java` | Add `processOverture()` method |
+| `Pois.java` | Add `processOverture()` method |
+
+## Planetiler Library Support
+
+Planetiler provides robust built-in support:
+
+1. **ParquetReader** - handles file reading, Hive partitioning, WKB/WKT geometry parsing
+2. **`Planetiler.addParquetSource()`** - adds Geoparquet to processing pipeline
+3. **`SourceFeature` interface** - common abstraction for all source types
+4. **Bounding box filtering** - built into ParquetReader for efficient spatial queries
+5. **Multi-file support** - reads multiple partitioned files efficiently
+
+## Implementation Phases
+
+### Phase 1: Core Infrastructure
+1. Add `--overture` argument and validation
+2. Add conditional `.addParquetSource()` calls for all Overture themes
+3. Update help text
+
+### Phase 2: Layer Implementation
+1. Implement `processOverture()` for Buildings layer (proof of concept)
+2. Test with Overture buildings data
+3. Implement `processOverture()` for remaining layers
+4. Create Overture→basemap schema mapping for each layer
+
+### Phase 3: Polish
+1. Test with complete Overture dataset
+2. Add integration tests
+3. Profile performance and optimize if needed
+4. Document Overture schema mappings
+
+## Key Implementation Notes
+
+1. **Routing mechanism:** All features from all Overture sources go to all registered handlers. Each handler filters by checking `feature.getSourceLayer()` value.
+
+2. **Hive partitions:** The `type=` value in partition paths becomes the source layer name. Example: files in `theme=buildings/type=building/` have source layer `"building"`.
+
+3. **Multiple files:** Each `.addParquetSource()` call processes many partitioned files via `Glob.of().resolve().find()`.
+
+4. **Source name:** All Overture sources use the same name `"overture"` because routing is by source layer, not source name.
+
+5. **No remote URL support:** Parquet sources don't support URLs directly. Users must download Overture data first or we must implement download logic separately.

 This document outlines how to expand Basemap.java to accept Overture Maps data from Geoparquet files as an alternative to OSM input.
 
+## Implementation Status
+
+**Phase 1 Complete (2025-12-29):** Basic infrastructure with land and water layers
+- Added `--overture` CLI flag accepting single Parquet file path
+- Implemented mutual exclusivity between `--overture` and `--area`
+- Conditional data source loading (Overture Parquet vs OSM+GeoPackage)
+- Natural Earth retained for low-zoom (0-5) rendering in both modes
+- Implemented Water.java::processOverture() for theme=base/type=water
+- Implemented Earth.java::processOverture() for theme=base/type=land
+- Output filename derived from input Parquet file basename
+- Successfully tested with lake-merritt-slice-overture.parquet
+
+**Remaining Work:**
+- Implement processOverture() methods for other layers (Buildings, Places, Roads, Transit, Landuse, Landcover, Boundaries, Pois)
+- Handle nested JSON fields properly (currently warnings for `names.primary` access)
+- Support for additional Overture themes beyond base theme
+
 ## Overview
 
 Add `--overture` argument to accept Overture Maps Geoparquet data as an alternative to `--area` (OSM data). These options are mutually exclusive.
 
+**Implementation Note:** The `--overture` argument accepts a **single Parquet file path**, not a directory. This differs from the original plan but matches the actual usage pattern in the Makefile.
+
 ## Overture Data Structure
 
 Overture Maps data is organized in Geoparquet files, sometimes Hive-partitioned but not always:

 ### 2. Data Source Configuration
 
-**Location:** `Basemap.java:214-222`
+**Location:** `Basemap.java:225-246` **IMPLEMENTED**
 
-Add a `.addParquetSource()` call for all Overture data when `--overture` is specified.
+Added conditional `.addParquetSource()` call for single Overture file when `--overture` is specified. Natural Earth source is **always added** for low-zoom (0-5) rendering.
 
 ```java
-if (!overtureBase.isEmpty()) {
-  // All Overture themes together - untested code, hopefully this works okay

 }
 ```
 
-**Important:** When using `--overture`, the three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) are NOT added because Overture's base theme already includes `water`, `land`, and `land_cover` types that serve the same purpose. The handler registration for these layers will remain unchanged but they will receive data from Overture's base theme instead of the GeoPackage files.
+**Important Changes from Original Plan:**
+- Natural Earth is **retained** in Overture mode for low-zoom rendering (zooms 0-5)
+- Single Parquet file path instead of directory with glob pattern
+- The three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) are NOT added in Overture mode
+- Overture's base theme `water` and `land` types provide zoom 6+ data
+- Natural Earth + Overture together provide complete zoom 0-15 coverage
 
 **Key points:**
-- All sources use name `"overture"` (routing is by source layer, not source name)
-- Enable Hive partitioning with `true` flag
+- Source name: `"overture"`
+- Enable Hive partitioning: `true`
 - ID extraction: `fields -> fields.get("id")`
-- Layer extraction: `fields -> fields.get("type")`
-- Use `Glob.of().resolve().find()` to get `List` of partitioned files
+- Layer extraction: `fields -> fields.get("type")` (gets "water", "land", etc. from Hive partition)
+- Single file path wrapped in `List.of()`
 
 ### 3. Source Handler Registration
 
-**Location:** `Basemap.java:36-103` (constructor)
+**Location:** `Basemap.java:88-104` (constructor)
+
+Add `registerSourceHandler("overture", ...)` calls for each layer.
+
+**IMPLEMENTED for Water and Earth layers:**
+
+```java
+// Water - Natural Earth (zooms 0-5) + Overture base/water (zooms 6+)
+if (layer.isEmpty() || layer.equals(Water.LAYER_NAME)) {
+  var water = new Water();
+  registerHandler(water);
+  registerSourceHandler("osm", water::processOsm);
+  registerSourceHandler("osm_water", water::processPreparedOsm); // OSM GeoPackage

+  registerSourceHandler("overture", water::processOverture);     // IMPLEMENTED
+}
+
+// Earth - Natural Earth (zooms 0-5) + Overture base/land (zooms 6+)

+  var earth = new Earth();
+  registerHandler(earth);

+  registerSourceHandler("overture", earth::processOverture);     // IMPLEMENTED
+}
+```
 
-Add `registerSourceHandler("overture", ...)` calls for each layer:
+**TODO for remaining layers:**
 
 ```java
 if (layer.isEmpty() || layer.equals(Buildings.LAYER_NAME)) {
   var buildings = new Buildings();
   registerHandler(buildings);
   registerSourceHandler("osm", buildings::processOsm);

-  registerSourceHandler("osm_land", earth::processPreparedOsm); // OSM GeoPackage
-  registerSourceHandler("overture", earth::processOverture); // NEW - from base theme
-}
+**Note:** The existing handlers for `osm_water`, `osm_land`, and `landcover` are kept because they're only called when those GeoPackage sources are added (OSM mode). When using `--overture`, those sources aren't added, so only the Natural Earth and Overture handlers are called.
 
-// Landcover - existing registrations remain, but data source changes
-if (layer.isEmpty() || layer.equals(Landcover.LAYER_NAME)) {

-  registerHandler(landcover);

+### 4. Layer Processing Methods
+
+**Location:** Individual layer files
+
+Add `processOverture()` methods in each layer class. Filter by `feature.getSourceLayer()` which comes from the Hive partition `type=` value.

Subject: [PATCH 57/76] Add comprehensive tests for Overture roads
 oneway/is_link extraction and line splitting

- Updated 6 existing tests to include access_restrictions and road_flags data
- Added 6 new splitting tests for partial bridge/tunnel/oneway/level application
- Tests use simple geometries (0,0)-(1,0) for easy verification
- All 12 tests failing as expected (property extraction and splitting not yet implemented)
- References real Overture feature IDs and OSM way IDs in comments

Subject: [PATCH 58/76] Implement Overture roads line splitting for partial
 bridge/tunnel/oneway/level properties

Major Changes:
- Created com.protomaps.basemap.geometry.Linear utility class for line splitting operations
- Rewrote Roads.processOverture() to handle fractional 'between' ranges from Overture data
- Implemented collectSplitPoints() to gather all split positions from road_flags, access_restrictions, and level_rules
- Implemented extractSegmentProperties() to determine which properties apply to each split segment
- Added emitRoadFeature() to create features with custom split geometries

Results:
- 15/21 tests now passing (6 original property extraction tests now pass)
- 6 splitting tests create correct features with correct attributes and geometries
- Only remaining issue: cosmetic Norm{} wrapper in test assertions (geometries are actually correct)

Implementation handles:
- Partial bridges via road_flags with 'is_bridge' flag
- Partial tunnels via road_flags with 'is_tunnel' flag
- Partial oneway restrictions via access_restrictions with heading='backward'
- Partial level changes via level_rules
- Overlapping property ranges (e.g., bridge + oneway on same segment)
- Multiple split points creating 2-5 output features per input feature

Subject: [PATCH 59/76] Fix Linear.splitAtFractions() to preserve intermediate
 vertices for curved roads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add comprehensive unit tests for line splitting with curves
- Rewrite Linear.splitAtFractions() to preserve all vertices between split points
- Add coordinate transformation from lat/lon to world coordinates before emitting
- All 9 new Linear tests pass, roads render correctly with curves preserved

-# Plan for Adding Overture Maps Support to Basemap.java
-
-This document outlines how to expand Basemap.java to accept Overture Maps data from Geoparquet files as an alternative to OSM input.
-
-## Implementation Status
-
-**Phase 1 Complete (2025-12-29):** Basic infrastructure with land and water layers
-- Added `--overture` CLI flag accepting single Parquet file path
-- Implemented mutual exclusivity between `--overture` and `--area`
-- Conditional data source loading (Overture Parquet vs OSM+GeoPackage)
-- Natural Earth retained for low-zoom (0-5) rendering in both modes
-- Implemented Water.java::processOverture() for theme=base/type=water
-- Implemented Earth.java::processOverture() for theme=base/type=land
-- Output filename derived from input Parquet file basename
-- Successfully tested with lake-merritt-slice-overture.parquet
-
-**Remaining Work:**
-- Implement processOverture() methods for other layers (Buildings, Places, Roads, Transit, Boundaries, Pois)
-- Handle nested JSON fields properly (currently warnings for `names.primary` access)
-- Support for additional Overture themes beyond base theme
-
-## Overview
-
-Add `--overture` argument to accept Overture Maps Geoparquet data as an alternative to `--area` (OSM data). These options are mutually exclusive.
-
-**Implementation Note:** The `--overture` argument accepts a **single Parquet file path**, not a directory. This differs from the original plan but matches the actual usage pattern in the Makefile.
-
-## Overture Data Structure
-
-Overture Maps data is organized in Geoparquet files, sometimes Hive-partitioned but not always:
-```
-theme=buildings/type=building/*.parquet
-theme=buildings/type=building_part/*.parquet
-theme=places/type=place/*.parquet
-theme=transportation/type=segment/*.parquet
-theme=transportation/type=connector/*.parquet
-theme=base/type=water/*.parquet
-theme=base/type=land/*.parquet
-theme=base/type=land_use/*.parquet
-theme=base/type=land_cover/*.parquet
-theme=base/type=infrastructure/*.parquet
-theme=base/type=bathymetry/*.parquet
-theme=divisions/type=division/*.parquet
-theme=divisions/type=division_area/*.parquet
-theme=divisions/type=division_boundary/*.parquet
-theme=addresses/type=address/*.parquet
-```
-
-**Note:** The base theme includes `water`, `land`, and `land_cover` types which replace the three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) used in OSM mode.
-
-## Code Changes Required
-
-### 1. Command-line Argument Handling
-
-**Location:** `Basemap.java:213-223` **IMPLEMENTED**
-
-Added `--overture` argument accepting a **single Parquet file path** (not directory).
-
-```java
-String area = args.getString("area", "Geofabrik area name to download, or filename in data/sources/", "");
-String overtureFile = args.getString("overture", "Path to Overture Maps Parquet file", "");
-
-// Validate mutual exclusivity
-if (!area.isEmpty() && !overtureFile.isEmpty()) {
-  LOGGER.error("Error: Cannot specify both --area and --overture");
-  System.exit(1);
-}
-if (area.isEmpty() && overtureFile.isEmpty()) {
-  area = "monaco"; // default
-}
-```
-
-**Help text updated** at `Basemap.java:176` to document `--overture=` option.
-
-### 2. Data Source Configuration
-
-**Location:** `Basemap.java:225-246` **IMPLEMENTED**
-
-Added conditional `.addParquetSource()` call for single Overture file when `--overture` is specified. Natural Earth source is **always added** for low-zoom (0-5) rendering.
-
-```java
-var planetiler = Planetiler.create(args)
-  .addNaturalEarthSource("ne", nePath, neUrl);  // ALWAYS added for low zooms
-
-if (!overtureFile.isEmpty()) {
-  // Add Overture Parquet source
-  planetiler.addParquetSource("overture",
-    List.of(Path.of(overtureFile)),
-    true, // enable Hive partitioning
-    fields -> fields.get("id"),
-    fields -> fields.get("type")
-  );
-} else {
-  // Add OSM and GeoPackage sources
-  planetiler
-    .addOsmSource("osm", Path.of("data", "sources", area + ".osm.pbf"), "geofabrik:" + area)
-    .addShapefileSource("osm_water", sourcesDir.resolve("water-polygons-split-3857.zip"),
-      "https://osmdata.openstreetmap.de/download/water-polygons-split-3857.zip")
-    .addShapefileSource("osm_land", sourcesDir.resolve("land-polygons-split-3857.zip"),
-      "https://osmdata.openstreetmap.de/download/land-polygons-split-3857.zip")
-    .addGeoPackageSource("landcover", sourcesDir.resolve("daylight-landcover.gpkg"),
-      "https://r2-public.protomaps.com/datasets/daylight-landcover.gpkg");
-}
-```
-
-**Important Changes from Original Plan:**
-- Natural Earth is **retained** in Overture mode for low-zoom rendering (zooms 0-5)
-- Single Parquet file path instead of directory with glob pattern
-- The three GeoPackage sources (`osm_water`, `osm_land`, `landcover`) are NOT added in Overture mode
-- Overture's base theme `water` and `land` types provide zoom 6+ data
-- Natural Earth + Overture together provide complete zoom 0-15 coverage
-
-**Key points:**
-- Source name: `"overture"`
-- Enable Hive partitioning: `true`
-- ID extraction: `fields -> fields.get("id")`
-- Layer extraction: `fields -> fields.get("type")` (gets "water", "land", etc. from Hive partition)
-- Single file path wrapped in `List.of()`
-
-### 3. Source Handler Registration
-
-**Location:** `Basemap.java:88-104` (constructor)
-
-Add `registerSourceHandler("overture", ...)` calls for each layer.
-
-**IMPLEMENTED for Water and Earth layers:**
-
-```java
-// Water - Natural Earth (zooms 0-5) + Overture base/water (zooms 6+)
-if (layer.isEmpty() || layer.equals(Water.LAYER_NAME)) {
-  var water = new Water();
-  registerHandler(water);
-  registerSourceHandler("osm", water::processOsm);
-  registerSourceHandler("osm_water", water::processPreparedOsm); // OSM GeoPackage
-  registerSourceHandler("ne", water::processNe);                 // Low-zoom (0-5)
-  registerSourceHandler("overture", water::processOverture);     // IMPLEMENTED
-}
-
-// Earth - Natural Earth (zooms 0-5) + Overture base/land (zooms 6+)
-if (layer.isEmpty() || layer.equals(Earth.LAYER_NAME)) {
-  var earth = new Earth();
-  registerHandler(earth);
-  registerSourceHandler("osm", earth::processOsm);
-  registerSourceHandler("osm_land", earth::processPreparedOsm);  // OSM GeoPackage
-  registerSourceHandler("ne", earth::processNe);                 // Low-zoom (0-5)
-  registerSourceHandler("overture", earth::processOverture);     // IMPLEMENTED
-}
-```
-
-**TODO for remaining layers:**
-
-```java
-if (layer.isEmpty() || layer.equals(Buildings.LAYER_NAME)) {
-  var buildings = new Buildings();
-  registerHandler(buildings);
-  registerSourceHandler("osm", buildings::processOsm);
-  registerSourceHandler("overture", buildings::processOverture); // TODO
-}
-
-if (layer.isEmpty() || layer.equals(Places.LAYER_NAME)) {
-  var place = new Places(countryCoder);
-  registerHandler(place);
-  registerSourceHandler("osm", place::processOsm);
-  registerSourceHandler("overture", place::processOverture); // TODO
-}
-
-if (layer.isEmpty() || layer.equals(Roads.LAYER_NAME)) {
-  var roads = new Roads(countryCoder);
-  registerHandler(roads);
-  registerSourceHandler("osm", roads::processOsm);
-  registerSourceHandler("overture", roads::processOverture); // TODO
-}
-
-// ... and others (Transit, Landuse, Landcover, Boundaries, Pois)
-```
-
-**Note:** The existing handlers for `osm_water`, `osm_land`, and `landcover` are kept because they're only called when those GeoPackage sources are added (OSM mode). When using `--overture`, those sources aren't added, so only the Natural Earth and Overture handlers are called.
-
-### 4. Layer Processing Methods
-
-**Location:** Individual layer files
-
-Add `processOverture()` methods in each layer class. Filter by `feature.getSourceLayer()` which comes from the Hive partition `type=` value.
-
-**IMPLEMENTED - Water.java::processOverture() (`Water.java:434-456`)**
-
-```java
-public void processOverture(SourceFeature sf, FeatureCollector features) {
-  String sourceLayer = sf.getSourceLayer();
-
-  // Filter by source layer - Overture base theme water
-  if (!"water".equals(sourceLayer)) {
-    return;
-  }
-
-  // Read Overture water attributes
-  String subtype = sf.getString("subtype"); // e.g., "lake", "river", "ocean"
-  String primaryName = sf.getString("names", "primary");
-
-  if (sf.canBePolygon()) {
-    features.polygon(LAYER_NAME)
-      .setAttr("kind", subtype != null ? subtype : "water")
-      .setAttr("name", primaryName)
-      .setAttr("sort_rank", 200)
-      .setPixelTolerance(Earth.PIXEL_TOLERANCE)
-      .setMinZoom(6)
-      .setMinPixelSize(1.0)
-      .setBufferPixels(8);
-  }
-}
-```
-
-**IMPLEMENTED - Earth.java::processOverture() (`Earth.java:78-91`)**
-
-```java
-public void processOverture(SourceFeature sf, FeatureCollector features) {
-  String sourceLayer = sf.getSourceLayer();
-
-  // Filter by source layer - Overture base theme land
-  if (!"land".equals(sourceLayer)) {
-    return;
-  }
-
-  features.polygon(LAYER_NAME)
-    .setAttr("kind", "earth")
-    .setPixelTolerance(PIXEL_TOLERANCE)
-    .setMinZoom(6)
-    .setBufferPixels(8);
-}
-```
-
-**TODO - Example for Buildings.java:**
-
-```java
-public void processOverture(SourceFeature feature, FeatureCollector features) {
-  String sourceLayer = feature.getSourceLayer();
-
-  // Filter by source layer (from Hive partition type=building or type=building_part)
-  if (!"building".equals(sourceLayer) && !"building_part".equals(sourceLayer)) {
-    return;
-  }
-
-  // Read Overture attributes
-  Double height = feature.getDouble("height");
-  String roofColor = feature.getString("roof_color");
-
-  // Extract nested names (Overture uses structured names object)
-  String primaryName = feature.getString("names", "primary");
-
-  String kind = "building_part".equals(sourceLayer) ? "building_part" : "building";
-  Integer minZoom = "building_part".equals(sourceLayer) ? 14 : 11;
-
-  features.polygon(LAYER_NAME)
-    .setId(FeatureId.create(feature))
-    .setAttr("kind", kind)
-    .setAttr("name", primaryName)
-    .setAttr("height", height)
-    .setAttr("roof_color", roofColor)
-    .setAttr("sort_rank", 400)
-    .setZoomRange(minZoom, 15);
-}
-```
-
-**Example for Places.java:**
-
-```java
-public void processOverture(SourceFeature feature, FeatureCollector features) {
-  String sourceLayer = feature.getSourceLayer();
-
-  // Filter by source layer
-  if (!"place".equals(sourceLayer)) {
-    return;
-  }
-
-  // Read Overture structured data
-  String primaryName = feature.getString("names", "primary");
-  String primaryCategory = feature.getString("categories", "primary");
-
-  // Map Overture categories to basemap place types
-  String placeType = mapOvertureCategory(primaryCategory);
-
-  features.point(LAYER_NAME)
-    .setAttr("name", primaryName)
-    .setAttr("place_type", placeType)
-    .setMinZoom(calculateMinZoom(primaryCategory));
-}
-```
-
-**Example for Water.java:**
-
-```java
-public void processOverture(SourceFeature feature, FeatureCollector features) {
-  String sourceLayer = feature.getSourceLayer();
-
-  // Filter by source layer - Overture base theme water
-  if (!"water".equals(sourceLayer)) {
-    return;
-  }
-
-  // Read Overture water attributes
-  String subtype = feature.getString("subtype"); // e.g., "lake", "river", "ocean"
-  String primaryName = feature.getString("names", "primary");
-
-  features.polygon(LAYER_NAME)
-    .setAttr("kind", subtype)
-    .setAttr("name", primaryName)
-    .setZoomRange(0, 15);
-}
-```
-
-**Example for Earth.java (land polygons):**
-
-```java
-public void processOverture(SourceFeature feature, FeatureCollector features) {
-  String sourceLayer = feature.getSourceLayer();
-
-  // Filter by source layer - Overture base theme land
-  if (!"land".equals(sourceLayer)) {
-    return;
-  }
-
-  features.polygon(LAYER_NAME)
-    .setAttr("kind", "land")
-    .setZoomRange(0, 15);
-}
-```
-
-**Key differences from OSM processing:**
-- Use `feature.getSourceLayer()` for routing, NOT tag checking
-- Source layer comes from Hive partition path (e.g., `type=building`)
-- Access nested JSON properties: `feature.getString("names", "primary")`
-- Overture uses `subtype` instead of OSM tag combinations
-- No `hasTag()` checks needed - source layer determines feature type
-
-### 5. Overture Schema Mapping
-
-Overture Maps uses a different schema than OSM:
-
-**Overture structure:**
-
-Overture features are primarily organized by "theme" and "type", these are the most important things to know about them:
-- "id" and "geometry" always exist
-- "level_rules" designates rendering z-order sections
-- "names"."primary" holds the most important name
-- theme=transportation and type=segment includes highways, railways, and waterways
-    - Highways have subtype=road, OSM-like "motorway", "residential", etc. class values, and "road_flags" to designate e.g. bridge or tunnel sections
-    - Railways have subtype=rail, "standard_gauge", "subway", etc. class values, and "rail_flags" to designate e.g. bridge or tunnel sections
-    - Waterways have subtype=water
-- theme=base includes land, land_cover, and water
-    - General land has type=land
-    - Bodies of water have type=water, "subtype" with type of water body, and "class" with further description
-    - Areas of land have type=land_cover and "subtype" with type of land cover
-- theme=buildings includes representations of buildings and building parts
-    - All buildings and building parts can have height in meters
-    - Whole buildings have type=building, and optionally boolean "has_parts"
-    - Parts of buildings have type=building_part and can show higher-detail parts (like towers vs. bases) instead a generic whole building
-
-Complete Overture schema reference is at https://docs.overturemaps.org/schema/reference/
-
-**Mapping examples:**
-- OSM `building=yes` → Overture `theme=buildings` + `type=building`
-- OSM `amenity=restaurant` → Overture `theme=places` + `type=place` + `categories.primary=restaurant`
-- OSM `highway=primary` → Overture `theme=transportation` + `type=segment` + `subtype=road`
-
-### 6. Output Filename
-
-**Location:** `Basemap.java:292-304` **IMPLEMENTED**
-
-Output filename is derived from the input Parquet file basename:
-
-```java
-String outputName;
-if (!overtureFile.isEmpty()) {
-  // Use base filename from input Parquet file
-  String filename = Path.of(overtureFile).getFileName().toString();
-  // Remove .parquet extension if present
-  if (filename.endsWith(".parquet")) {
-    outputName = filename.substring(0, filename.length() - ".parquet".length());
-  } else {
-    outputName = filename;
-  }
-} else {
-  outputName = area;
-}
-planetiler.setOutput(Path.of(outputName + ".pmtiles"));
-```
-
-**Example:** Input `data/sources/lake-merritt-slice-overture.parquet` → Output `lake-merritt-slice-overture.pmtiles`
-

-## Planetiler Library Support
-
-Planetiler provides robust built-in support:
-
-1. **ParquetReader** - handles file reading, Hive partitioning, WKB/WKT geometry parsing
-2. **`Planetiler.addParquetSource()`** - adds Geoparquet to processing pipeline
-3. **`SourceFeature` interface** - common abstraction for all source types
-4. **Bounding box filtering** - built into ParquetReader for efficient spatial queries
-5. **Multi-file support** - reads multiple partitioned files efficiently
-
-## Implementation Phases
-
-### Phase 1: Core Infrastructure
-1. Add `--overture` argument and validation
-2. Add conditional `.addParquetSource()` calls for all Overture themes
-3. Update help text
-
-### Phase 2: Layer Implementation
-1. Implement `processOverture()` for Buildings layer (proof of concept)
-2. Test with Overture buildings data
-3. Implement `processOverture()` for remaining layers
-4. Create Overture→basemap schema mapping for each layer
-
-### Phase 3: Polish
-1. Test with complete Overture dataset
-2. Add integration tests
-3. Profile performance and optimize if needed
-4. Document Overture schema mappings
-
-## Key Implementation Notes
-
-1. **Routing mechanism:** All features from all Overture sources go to all registered handlers. Each handler filters by checking `feature.getSourceLayer()` value.
-
-2. **Hive partitions:** The `type=` value in partition paths becomes the source layer name. Example: files in `theme=buildings/type=building/` have source layer `"building"`.
-
-3. **Multiple files:** Each `.addParquetSource()` call processes many partitioned files via `Glob.of().resolve().find()`.
-
-4. **Source name:** All Overture sources use the same name `"overture"` because routing is by source layer, not source name.
-
-5. **No remote URL support:** Parquet sources don't support URLs directly. Users must download Overture data first or we must implement download logic separately.
