 ## Build, Test, and Development Commands
 - Create a venv: `uv venv && source .venv/bin/activate`. Install deps: `uv sync` (generates `uv.lock`).
 - If wheels fail, install system GDAL first (e.g., `brew install gdal` or `apt-get install gdal-bin libgdal-dev`), then rerun `uv sync`.
+- Prepare the directory tree (raw/archives/work/exports): `bash setup_dirs.sh`.
 - Heightmap export (rebuilds VRT if absent): `uv run python export_heightmaps.py`.
 - Orthophoto export: `uv run python export_ortho_tiles.py` (requires JP2s under `raw/dop/jp2/`; legacy `raw_dop/jp2/` still works).
 - Refresh VRT manually if needed: `gdalbuildvrt work/dgm.vrt raw/dgm1/*.tif` (legacy: `raw_dgm1/*.tif`).

 ### Repository Layout
 - `raw/` — preferred working inputs (not versioned): `raw/dgm1/`, `raw/dop/jp2/`, `raw/citygml/lod1/`, `raw/citygml/lod2/`. Legacy directories (`raw_dgm1/`, `raw_dop/`, `raw_3dgeb_lod1/`, `raw_3dgeb_lod2/`) are still honored by the scripts.
