I have a raster in ArcGIS which has a number of cells with the values 9999, showing that the data could not be generated for that cell. I want to convert all of these 9999 values to NoData, so that then I can do statistics on the dataset without getting crazy results.
How should I do this?
I have tried to use the reclassify tool, just adding one reclassification from 9999 -> No Data, but it seems to change all of the other values as well. Is there a way to do a reclassification which only does the changes you specify, and leaves all other values alone?
In case it matters, my dataset is a TIFF, with floating point values in it.
