### SPW waterbed raster
The official 2023-05-23 SPW bathymetry ZIP is integrated only through the
bounded operator. Stage the immutable ZIP under persistent storage and run:
```bash
docker exec geointel python /app/scripts/import_spw_bathymetry.py \
--base-url http://127.0.0.1:8000 \
--project-name "Belgium and North Sea Workbench" \
--area "RC Golden - Wallonia urban-rural" \
--bbox 4.85,50.45,4.87,50.47 \
--raw-zip /app/storage/operator-evidence/spw-bathymetry/2023-05-23/raw/BATHY_50CM_ALTITUDE_DNG_GEOTIFF_3812.zip \
--output-dir /app/storage/operator-evidence/spw-bathymetry/2023-05-23/derived
```
The script validates the pinned official checksum, safe archive members,
EPSG:3812, one Float32 band, approximately 0.5 m cells and nodata `-9999`.
It then creates a bounded COG and uploads it through `/datasets/upload`.
`POST .../raster/bathymetry/select` returns waterbed elevation in mDNG,
surveyed surface and coverage. Current depth, volume and datum conversion stay
unavailable without a compatible water-surface source. Selection analysis is
bounded by `BATHYMETRY_RASTER_MAX_PIXELS` (30 million by default).
