* Gridded building roof heights can be used as supplementary data for the identification of roof points. A *PostgreSQL* script to [rasterize roofs heights](/src/postgresql/3DCityDB_rasterize_lod2_roof_heights.pgsql) for 3D city models stored in a [3D City Database](https://www.3dcitydb.org/3dcitydb/) is included in the repository.Information on how to set up the database and run the script is given in [this readme](/src/postgresql/readme_pgsql.md)
## Key Features
-### Urban forest classification
+### Urban Forest Classification
The classified point cloud and a canopy height model are generated as output.
-### Individual crown parameterization
+### Individual Crown Parameterization
Tree positions as point features and crown segments as polygon features are generated as output.

The prototypes differ in their ratio of crown height to trunk height. The variety ranges from only crown to almost exclusively trunk.
