 - Refresh VRT manually if needed: `gdalbuildvrt work/dgm.vrt raw/dgm1/*.tif`.
 - Inspect a result: `gdalinfo export_unity/height_png16/<tile>.png | head` to sanity-check bounds and scaling.
 - Populate raw data from archives: `uv run python geodata_to_unity.py --use-archive --export all` (unzips `archive/*` and copies dop20 filelist).
+- Rebuild VRTs after moving data: add `--force-vrt`.
 - Expected warning: `Computed -srcwin ... falls partially outside source raster extent` means the DOP coverage is slightly smaller than the tile footprint; edge pixels will be filled with NoData/zeros. Add adjacent JP2s or shrink the requested window if you need to silence it.
 - Scripts accept CLI overrides (e.g., `--config`, `--raw-dgm1-path`, `--raw-dop20-path`, `--export`); run `uv run python geodata_to_unity.py -h` to see options.

 - Inspect an output tile: `gdalinfo export_unity/height_png16/<tile>.png | head`
 - Override config paths: use `--config <path>`, `--raw-dgm1-path <dir>`, `--raw-dop20-path <dir>`.

 ### Workflow Notes
 - The pipeline computes a global min/max from the VRT to scale all tiles consistently; adjust `heightmap.out_res` or `heightmap.resample` in `geodata_config.json` if your AOI or target resolution changes.
