Is there a simple way to find the total area of a raster EXCLUDING NoData cells?
I can load my raster into a Mosaic Dataset, run the Build Footprints tool, and get a footprint that cuts out NoData around the margins, but this will not handle any NoData areas that are within a data-filled area.
Counting cells is no good if the raster covers a large latitudinal range (as cells are likely to have different areas across latitudes).
So I guess that leaves either Spatial Analyst or a mixture of RasterToNumPyArray / NumPyArrayToRaster (converting all cells with values to a single value), followed by the Raster To Polygon tool.
Somehow it seems like I'm missing something though - as the task "feels" like it should have a simpler solution!
