Get nodata value from raster using arcpy

WadeWall

Hi all,

I am using ArcGIS Pro 2.9. I want to use arcpy to obtain the nodata value for a raster, but can't figure out how to do that. It is not listed in getRasterProperties(). Any help would be appreciated.

I am not sure how I missed that in the documentation. I appreciate your assistance and not sure I want my question preserved for all eternity, but maybe someone else will ask the same question. Thanks again
