I am trying to mosaic 3 data sets, 2 of which are bathymetry and 1 elevation data sets. The bathy data overlap the elevation data where it has NoData and the elevation data overlap the bathy data where there is NoData.
My problem is I keep getting NoData from 1 or the other dataset obscuring the actual data. This normally occurs after I Build Overviews. Creating footprints also does not work, ArcCatalog just tends to crash.
I have already created mosaics of the individual data sets and then try to mosaic using these. I have simplified my elevation data set and removed al the little islands and small NoData areas within the data set.
