BREAKING CHANGES

  • landuse layer: Move national_park, protected_area, and nature_reserve to landuse layer from natural layer as they are not natural but cultural. #47
  • landuse layer: OSM features with leisure tag are now mapped to individual kind values instead of all erroneously to park. #47
  • landuse layer: Features with amenity tag are mapped to individual kind values instead of all erroneously to school when not hospital. #47
  • natural layer: Moved national_park, protected_area, and nature_reserve to landuse layer. #47
  • places layer: OSM state (province) is now region (preparing for v4 Tilezen changes) #47
  • places layer: OSM city is now locality (preparing for v4 Tilezen changes) #47
  • places layer: OSM town and village are now locality ("city") instead of neighbourhood (fixing v2 series bug and preparing for v4 Tilezen changes) #37

ENHANCEMENTS

  • Significant performance improvements to reduce p99 file sizes globally (-XX%) at all zooms to under 200 kb. Changes include: ...
  • Core Tilezen schema properties added::
    • pmap:kind is present on every feature now in every layer
    • pmap:kind_detail is optionally present on some features in some layers
    • DEPRECATION WARNING: in v4, the pmap: prefix will be removed (so pmap:kind will become simply kind)
  • Core OSM tags for different kinds of places have been augmented, but...
    • DEPRECATION WARNING: These OSM tags are marked for deprecation in v4 schema, do not use these for styling. They aren't needed and take up extra file size.
    • If an explicate value is needed it should be a kind, or included in kind_detail. If there is a gap, please file an issue so it can be addressed.
  • Less names, now with label placements:
    • Names have been removed from most features at early and mid-zooms (to also reduce file size)
    • Names have been kept on some features at early- and mid-zooms when they are known to be used for map display
    • When features do have names, a pmap:min_zoom is added to achieve more predictable label collisions client side.
      • DEPRECATION WARNING: in v4, the pmap: prefix will be removed (so pmap:min_zoom will become simply min_zoom)
  • Zoom ranges of most features have been adjusted to remove details (and reduce file size) at early and mid-zooms. #47
  • boundaries layer: Add boolean indication of disputed lines #37
  • boundaries layer: Use Natural Earth for low zoom boundary lines, including disputed status #47
  • boundaries layer: Don't export admin_level 1, 3, 5, and 7 – those generally aren't styled and are taking up a lot of file size even at very low zooms #47
  • boundaries layer: Adjust zoom range of county lines to show starting at zoom 8 instead of 10. #47
  • buildings layer: Adjust zoom ranges, push building_part kind features to later zooms (to reduce file size) #47
  • buildings layer: Quantize height tag at mid-zooms so more buildings merge in post-processing (to reduce file size) #47
  • buildings layer: Add optional min_height property to enable 2.5D and 3D visualizations #47
  • earth layer: Add 8 px buffer for Natural Earth sourced features at low zooms. #47
  • landuse layer: Add new kind values for: beach, pier, zoo, military, naval_base, airfield, cemetery, recreation_ground, winter_sports, quarry, park, and forest. #47
  • landuse layer: Add new national_park kind (versus park), looking at operator tag to derive this from OSM to emphasize US National Park Service in United States of America and elsewhere #47
  • landuse layer: Improve detection of forest kind (versus wood), looking at operator tag to derive this from OSM to emphasize National Forests in United States of America and elsewhere #47
  • landuse layer: Remove names to reduce tile sizes (see the pois layer for calculated label points) #47
  • landuse layer: Reduce small polygons to improve figure-ground contrast and reduce file size. #47
  • landuse layer: Add boundary, landuse, leisure, and natural properties from OSM tags (though don't use them to be v4 safe) #47
  • natural layer: Add new kind value for grass #47
  • natural layer: Update to the same pmap:kind coallesce as in the landuse layer #47
  • natural layer: Remove boundary and leisure properties (they moved to landuse layer along with the relevant featurse) #47
  • natural layer: Remove small polygons to improve figure-ground contrast and reduce file size. #47
  • natural layer: Merge polygons with similar attributes to reduce file size. #37
  • natural_lines layer: Show river lines 3 zooms earlier at zoom 9. #47
  • natural_lines layer: For linear water features like rivers – add tunnel / bridge indicator with pmap:level (same as roads layer) #47
  • natural_lines layer: Add bridge, tunnel, and layer properties from OSM. #47
  • natural_lines layer: Add intermittent boolean indicators. #47
  • natural_points layer: Show ocean and sea label points much earlier. #47
  • natural_points layer: Add calculated label positions for water features (like lake, reservoir, swimming_pool and other terrestial water features; and bay, strait, fjord marine featuers) #47
  • natural_points layer: Add alkaline, intermittent, and reservoir boolean indicators. #47
  • natural_points layer: Add natural, landuse, leisure, water, and waterway properties from OSM (though don't use them to be v4 safe) #47
  • places layer: Use Natural Earth for low-zoom locality features (to reduce file size) #47
  • places layer: Add server-side label collisions with a label grid to reduce number of places in tiles, especially at mid-zooms. #47
  • places layer: Remove country and region labels from mid- and high-zooms (still present at low-zooms) #47
  • places layer: Add pmap:kind_detail for original OSM "place" tag values (including "city" instead of "locality") #47
  • places layer: Add pmap:population_rank for a quantized and backfilled population approximation. #47
  • places layer: Curate custom min_zooms for country and region (state/province) labels to removes many labels from early zooms when they couldn't reasonably be labeled anyhow (to reduce file size) #47
  • pois layer: Add new national_park kind (versus park), looking at operator tag to derive this from OSM to emphasize US National Park Service in United States of America and elsewhere #47
  • pois layer: Improve detection of forest kind (versus wood), looking at operator tag to derive this from OSM to emphasize National Forests in United States of America and elsewhere #47
  • pois layer: Add allow listed OSM features from natural (beach) and landuse (cemetery, recreation_ground, winter_sports, quarry, park, forest, military) tags. #47
  • pois layer: Add amenity, attraction, boundary (select), craft, historic, landuse (select), natural (select), shop, railway (select), and tourism features and exported OSM tag to schema property (though don't use them to be v4 safe) #47
  • pois layer: Add additional pasthru unrestricted OSM values from attraction, craft, historic, landuse, leisure, and natural tags. This augments amenity, railway, shop, and tourism. #47
  • pois layer: Add cuisine, religion tags (though use pmap:kind_detail instead to be v4 safe) #47
  • pois layer: Add iata property on airport kind features to indicate if they have international service. #47
  • pois layer: Derive label centroids from OSM ways and relations features to hugely increasing the number of included features #47
  • pois layer: Add server-side label collisions with a label grid to reduce number of features in tiles at mid-zooms (all features still included at max_zoom) #47
  • pois layer: Add smattering of higher priority (even within a kind) features at earlier zoom levels (eg based on feature area and/or height). This primarily effects aerodrome, airfield, cemetery, college, forest, golf_course, grocery, hospital, library, marina, military, national_park, nature_reserve, naval_base, park, post_office, protected_area, stadium, supermarket, townhall, university, and zoo, or very large building area derived labels, or very tall height building area derived labels. #47
  • pois layer: Indicate with pmap:min_zoom property when a feature first became eligible to be in tiles, and mark max_zoom features to hide until later display zooms. Use this pmap:min_zoom property to setup client-side labe collisions. NOTE: In v4 it'll be renamed to just min_zoom. #47
  • roads layer: Modify ref tag values to remove some prefix values and remove whitespace values (for easier construction into client side shields with narrower graphics). #37
  • roads layer: Add shield_text_length for the integer lenth of the ref tag (with transformations) to more quickly converge towards Tilezen syntax. Can be paired with new network property to display client-side road shields. #37
  • roads layer: Add network with values of US:I, US:US or other. Can be paired with new shield_text_length and ref properties to display client-side road shields. #37
  • roads layer: Add pmap:kind_detail for values of service tag for other kind roads (eg for parking_aisle features) #47
  • roads layer: Remove name and ref tags from low- and mid-zooms selectively by road class to improve merging and reduce file size. #47
  • roads layer: Add pier kind lines. See also new pier areas in the landuse layer. #47
  • roads layer: Remove small lines at low- and mid-zooms to improve figure-ground contrast and reduce file size. #37

  • transit layer: Show certain kinds of railway (like light_rail and disused) later. #47
  • transit layer: Indicate with pmap:kind_detail the value of the relevant service, ferry, or aerialway tags. #47
  • transit layer: Add tunnel / bridge indicators with pmap:level (same as roads layer in v2), and layer property. #47
  • transit layer: Add network, ref, route, and service properties. #47
  • transit layer: Add aerialway, aeroway, highspeed, man_made, and railway properties (though don't use them to be v4 safe) #47
