map_raster

mapraster.main.map_raster(raster_ds, originalDataset, footprint, cross_antimeridian=False)

Map a raster onto an image grid defined by originalDataset.

Parameters:

• raster_ds (xarray.Dataset or xarray.DataArray) – Raster with valid .rio accessor.

• originalDataset (xarray.Dataset) – Dataset defining the target image grid (lon/lat in image dims).

• footprint (shapely.geometry.Polygon) – Footprint of the target grid.

• cross_antimeridian (bool, default False)

Return type:

xarray.Dataset or xarray.DataArray

_get_image_dims

mapraster.main._get_image_dims(ds)

Infer image dimensions from longitude/latitude variables, excluding ‘pol’ if present.
