Changelog

Unreleased

Fixed

  • Fixed the import of implicit geometries when import filters are used.

1.3.0 - 2026-03-09

Added

  • Added ImplicitGeometryScope reader option to control how implicit geometries are shared between top-level features when reading CityGML/CityJSON files.
    • GLOBAL (default): implicit geometries are parsed once and reused across all top-level features.
    • TOP_LEVEL_FEATURE: implicit geometries are resolved per top-level feature and reused only within that feature. This mode produces self-contained features, simplifying parallel processing. A new ReferenceResolver helper class provides convenient access to referenced objects. With this mode, the resulting top-level feature structure matches that of the database export. #73

Changed

  • Improved error handling when writing ZIP output files.
  • Improved import performance for features having many appearances.
  • Improved import performance for features with deeply nested sub-features.
  • Removed TextureImageProperty and Reference from the data model.
  • Reworked DatabaseAdapter interface to simplify support for databases beyond PostgreSQL/PostGIS.

Fixed

  • Fixed an issue where the file name was not correctly retrieved from texture images provided as URLs.
  • Fixed reading and importing duplicate sub-features within the same top-level feature.
  • Fixed local references to library objects in CityGML exports.
  • Fixed missing sub-features referenced from multiple parent features in CityGML exports.
  • Fixed CityJSON export to avoid using newline-delimited CityJSONSeq for CityJSON version 1.0.
  • Fixed loading of database and I/O adapters as external plugins.

1.2.0 - 2025-12-06

Added

  • Added a Java API for querying and processing feature changes from the feature_changelog table and aggregating them into change regions.
  • Added the placeholders @file_path@, @file_name@, @content_path@, and @content_name@ for the --lineage option of the import command, allowing file and ZIP entry paths and names to be imported as feature metadata. #70
  • Added the --creation-date option to the import command to overwrite creation dates from the input files. #71
  • Added indexMode to the JSON configuration of the import and delete commands. #67
  • Added the --compact option to the info command to generate a more concise database report.
  • Added methods to PostgresqlAdapter for retrieving the installed PostGIS and SFCGAL versions from the connected database.

Changed

  • Unified JSON output of the connect command with other commands. No JSON is generated in case of an error anymore.
  • Password prompting is now only supported if a console is available. Passwords are no longer read from stdin.
  • Generic attributes are now grouped by feature types in the database report generated by the info command.
  • Renamed the JSON schema connection-status.schema.json to connection-info.schema.json.
  • Updated ModelObjectWriter to support thread-safe writing of model objects to a single file or stream.
  • Updated ModelObjectReader to support reading model objects into a list or consuming them in chunks.
  • Removed the FeatureCollection class due to changes in ModelObjectWriter and ModelObjectReader.

Fixed

  • Fixed 2D spatial queries on geometry_data so they no longer fail when encountering PolyhedralSurface geometries.
  • The CLI option --import-mode no longer overrides the JSON configuration even when not explicitly set on the command line.
  • Fixed an NPE in the info command when changelog tracking is enabled.
  • The last_modification_date now defaults to the current import time and is no longer tied to creation_date.
  • CLI options for appearance or LoDs in the export command no longer overwrite a query in the JSON configuration.
  • Fixed start scripts to respect the 8191-character command line limit on Windows.

1.1.0 - 2025-08-24

Added

  • Added the connect command to test connections to a 3DCityDB instance. This command supports optional JSON output, which can be written to stdout or a file. #64
  • Introduced the info command for generating a summary report of 3DCityDB contents. Reports can be produced in JSON format and written to stdout or a file for further processing. #61
  • Added support for XSLT/XPath 2.0 and 3.0 to the citygml import and citygml export commands.
  • Added the --output option to the index status command, enabling the index status list to be written as JSON to stdout or a file.

Changed

  • Updated and harmonized CLI options and their descriptions.
  • Texture coordinates are now processed and represented as float values instead of double.
  • Replaced the hard dependency on Apache Log4j with SLF4J as the logging abstraction for all API modules. #62

Fixed

  • Fixed support for time-based validity options in the JSON configuration.
  • Fixed count methods in SqlHelper to generate correct SQL statements.
  • Ensured operands are properly cast to geometry in SpatialOperatorHelper to prevent SQL exceptions.
  • Resolved MVStoreException: Chunk not found errors when resolving references during imports.

1.0.0 - 2025-03-17

This is the initial release of citydb-tool.
