Hi everyone,
I have a complex raster which has nodata values within it. I want to be able to extract the areas of nodata within it but not the nodata values that surrounds the grid (all around the extent). The simplest example would be a donut. I want to pull out the donut hole (perhaps by converting it to ones) but leave the area outside the donut as nodata.
If I do a simple reclassify of nodata, all the holes and the entire area around the grid gets converted. I don't have a raster mask I could use to pull out these nodata values.
Anyway to do this in spatial analyst???
Thanks,
Dennis
