 - GDAL installed with Python bindings (`osgeo` importable).
 - Python 3.9+ available on PATH.
 - DGM1 source tiles placed in `raw_dgm1/` as `dgm1_<utm_zone>_<easting>_<northing>.tif` (with matching `.tfw` files).
+- Raw inputs (`raw_dop/`, `raw_3dgeb_lod1/`, `raw_3dgeb_lod2/`) are **kept out of git**; keep them locally or document how to fetch/regenerate.
 
 ### Repository Layout
 - `raw_dgm1/` — input rasters (not versioned).
+- `raw_dop/` — raw orthophoto downloads (JP2/J2W/XML), ignored in git.
+- `raw_3dgeb_lod1/`, `raw_3dgeb_lod2/` — CityGML building tiles, ignored in git.
 - `work/` — intermediates such as `dgm.vrt` and `_tmp.tif` files; safe to delete/regenerate.
 - `export_unity/height_png16/` — final 16-bit PNG heightmaps for Unity import.
 - `export_unity/tile_index.csv` — manifest mapping tile IDs to world bounds and global min/max used for scaling.

    This builds `work/dop.vrt` if missing and writes `export_unity/ortho_jpg/<tile>.jpg` + `.jgw` aligned to `tile_index.csv`.
 
 ### Buildings
-The building export pipeline is temporarily disabled while we choose a mesh conversion approach (GDAL lacks a native OBJ writer). CityGML LoD2 sources remain in `raw_3dgeb_lod2/`; consider CityGML→glTF/OBJ tools (e.g., citygml-tools + cityjson2gltf) for future integration.
