exact_extract

wrong path, exact_extract is a top-level function

Extract zonal statistics from a raster using polygon geometries.

from exactextract import exact_extract import geopandas as gpd import rasterio # Load raster with rasterio.open('raster.tif') as src: raster = src.read(1) affine = src.transform # Load polygons gdf = gpd.read_file('polygons.shp') # Run zonal stats results = exact_extract(raster, affine, gdf.geometry, ops=['mean', 'sum']) print(results)

Debug

Known issues

gotchaThe `exact_extract` function expects raw numpy arrays and affine transforms, not file paths. Use rasterio or similar to load the raster data first.

fix

Load raster using rasterio.open() and pass the array and transform directly.

affects: *

gotchaGeometries must be in the same coordinate reference system (CRS) as the raster. No automatic reprojection is performed.

fix

Ensure vector geometries are reprojected to match the raster CRS using geopandas.to_crs() before calling exact_extract.

affects: *

deprecatedThe `extract` function is deprecated in favor of `exact_extract`.

fix

Use `from exactextract import exact_extract` instead.

affects: <0.3.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'exactextract'

Library not installed or installed in a different environment.

fix

Run `pip install exactextract` in the target Python environment.

ValueError: Input raster and features must have the same CRS

Polygons and raster have different coordinate reference systems.

fix

Reproject the vector features to match the raster CRS using gdf = gdf.to_crs(raster_crs).

TypeError: exact_extract() got an unexpected keyword argument 'ops'

The `ops` parameter was introduced in version 0.2.0; using older version.

fix

Upgrade to exactextract >=0.2.0: `pip install --upgrade exactextract`.
