Those two layers put the id in ID, and carry neither a land cover class nor a declared area, so the area comes from the geometry and the crop columns are left out rather than shipped empty.

A dozen blocks across the three editions are several polygons, and the base converter checks the ids before it explodes them. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DVx9uQV2QPM8ecPAY3ZjXG

lawi:LPIS-Referenzparzellenare reference parcels, so the title now matchesde_mvandde_sh, which publish the same kind of layer.The 2023 and 2024 layers have a different schema from 2025: the id is in
ID, beside the driver's own feature id, and there is no land cover class and no declared area. The area is measured from the geometry (EPSG:25832, so already m²) and the crop columns are dropped for those editions rather than shipped empty in every row.A dozen blocks across the three editions are several polygons, so the split moves into
migrate()and the parts are numbered.Based on #286 for
split_multipart.🤖 Generated with Claude Code
