xdem.DEM.crop

DEM.crop(crop_geom, mode='match_pixel', *, inplace=False)

Crop the raster to a given extent.

Match-reference: a reference raster or vector can be passed to match bounds during cropping.

Reprojection is done on the fly if georeferenced objects have different projections.

Parameters:

• crop_geom (Union[TypeVar(RasterType, bound= Raster), Vector, list[float], tuple[float, ...]]) – Geometry to crop raster to. Can use either a raster or vector as match-reference, or a list of coordinates. If crop_geom is a raster or vector, will crop to the bounds. If crop_geom is a list of coordinates, the order is assumed to be [xmin, ymin, xmax, ymax].

• mode (Union[Literal['match_pixel'], Literal['match_extent']]) – Whether to match within pixels or exact extent. 'match_pixel' will preserve the original pixel resolution, cropping to the extent that most closely aligns with the current coordinates. 'match_extent' will match the extent exactly, adjusting the pixel resolution to fit the extent.

• inplace (bool) – Whether to update the raster in-place.

Return type:

Optional[TypeVar(RasterType, bound= Raster)]

Returns:

A new raster (or None if inplace).
