I have a raster with gaps in it. I want to fill these in with averages of surrounding cells using ArcGIS 10.2 for Desktop.
I have tried "Focal Statistics" but it averages EVERY cell and not just the gaps.
I have tried [Mosaic].IsNull.Con([Average], [Mosaic]) found here Patching but don't know how to implement it/it won't work for me
I have tried Map ALgebra but I think they were using versions before 10.2.
What I want. Make a fake raster with gaps filled in. Use the fake raster to fill in the gaps of the real raster without replacing the points with actual data.
