Basic areal interpolation using area weighting.

from tobler import areal_interpolation import geopandas as gpd # Example: area weighted interpolation source_gdf = gpd.read_file('source.shp') target_gdf = gpd.read_file('target.shp') result = areal_interpolation.area_weighted( source_gdf, target_gdf, extensive_variables=['population'] ) print(result.head())

Debug

Known issues

breakingtobler 0.14.0 requires Python >=3.12. Older Python versions are not supported.

fix

Upgrade Python to 3.12 or higher.

affects: >=0.14.0

gotchaPolygon data must have a valid geometry column (default 'geometry'). Non-standard geometry column names will cause errors.

fix

Ensure GeoDataFrame has a geometry column; use gdf.set_geometry('geom') if needed.

affects: all

deprecatedThe function 'tobler.area_weighted' is deprecated in favor of 'tobler.areal_interpolation.area_weighted'.

fix

Use 'from tobler.areal_interpolation import area_weighted'.

affects: <0.14.0
