Nodata Masks — rasterio documentation - Read the Docs

Tīmeklis2024. gada 1. nov. · Rasterio's reproject does intend to support masked arrays, but it seems to fail in this case. One problem is that the .fill_value of your masked array is used as src_nodata (see these lines). That is wrong, because the actual .data in the masked array underneath the mask might have different values than .fill_value.
