I am applying a very straight forward nested Con/IsNull statement to set NoData to a uniform background value. I have my analysis environment set to a desired extent and a mask specified to provide an area that I want values written to. The resulting raster values are all 0. It looks like the raster calculator is not honoring the nested IsNull statement. My raster is rather large, floating point imagine format covering the entire state of Montana at 30m (col 30033, row 18409, 2.06GB). Any ideas on what is going on or an alternative approach?
Raster calculator statement.
Con(IsNull("probs.img"), 0, "probs.img")
I am running ArcGIS 10 SP2 on a 64bit MS Server 2008 OS.
