eodal.core.utils.raster.get_raster_attributes(riods: DatasetReader) → Dict[str, Any]

extracts immutable raster attributes (not changed by reprojections, resampling) and returns them as a dictionary.

Code taken from https://github.com/pydata/xarray/blob/960010b00119367ff6b82e548f2b54ca25c7a59c/xarray/backends/rasterio_.py#L359

Parameters:

riods – opened rasterio data set reader

Returns:

dictionary with extracted raster attributes (attrs)

eodal.core.utils.raster.spatial_to_image_coordinates(x: float, y: float, affine: ~affine.Affine, op=<built-in function floor>) → Tuple[int, int]

Convert spatial x and y coordinat to image coordinates (row + column)
