| edge-clip | clip an input layer to an overlay layer |
| edge-stitch | close seams in a tiled layer |
| change | classify changes between two polygon layer versions |
| code-create | assign a fresh hierarchical code, ranked per parent |
| code-update | carry codes over from an old layer to a new one |
| name-detect | check unit names for blanks, duplicates and encoding errors |
| name-clean | fix spacing, invisible characters and encoding errors in unit names |
| package | dissolve, label, and line-ify a layer in one call |
| package-polygons | dissolve a layer into coarser admin levels |
| package-points | one label point per admin unit |

Installation
Install with uv, pip/pipx, conda or Homebrew:
uv tool install topo-tools # CLI
uv add topo-tools # Python library
pip install topo-tools # CLI or library
pipx install topo-tools # CLI
conda install -c conda-forge topo-tools # CLI or library, recommended on Windows
brew install OCHA-DAP/topo-tools/topo-tools # macOS/Linux, no Python tooling
Supported Formats
Polygon inputs/outputs: GeoParquet (.parquet), GeoPackage (.gpkg),
Shapefile (.shp), GeoJSON (.geojson). Output format matches input format.
change's tabular changelog is CSV or GeoParquet only; its spatial overlay
layer supports the same four formats as the other tools.
See CONTRIBUTING.md for development setup.
