What swisslandstats-geopy is

swisslandstats-geopy is a free Linux Python package that extends pandas DataFrames for Swiss Federal Statistics Geodata, or GEOSTAT. It automatically reads GEOSTAT inventory CSV files into dataframes, then exports dataframe columns as NumPy arrays or GeoTIFF files. Dataframes can be clipped with vector geometries; place-name clipping requires osmnx, while vector clipping requires geopandas. The package can also plot information as raster maps. The documentation uses land-use data and population and household statistics as example datasets. It is intended for researchers and developers in environmental sciences and GIS building repeatable, reproducible workflows with SFSO geodata. Installation instructions cover conda and pip. The project recommends installing rasterio with conda to avoid possible GDAL issues, including those involving Swiss EPSG coordinate reference systems. It is distributed under GPL-3.0. PyPI lists version 0.12.0, released January 27, 2025. Listed TODOs include colormaps, datasets without land-use or land-cover columns, and merging multiple CSV dataframes.

Who it suits

It suits environmental-science and GIS researchers or developers working with Swiss GEOSTAT data. It is designed for repeatable workflows on Linux.

Getting started

1. Install the package using the conda or pip instructions.
2. For rasterio, use the project's recommended conda installation to avoid potential GDAL issues.
3. Load GEOSTAT inventory CSV files into dataframes.
4. Use vector clipping with geopandas, or place-name clipping with osmnx.
5. Export columns as NumPy arrays or GeoTIFF files, or plot raster maps.

Verdict

swisslandstats-geopy combines GEOSTAT loading, conversion, clipping, and mapping in a pandas-oriented workflow. Users should account for its optional dependencies and the project’s listed TODOs.
