I have a rather large raster image that was built initially from LAS files. I converted the LAS files to 15 foot resolution flt surfaces, and mosaiced them together in ArcCatalog (260 of them in all). I now have a seemless raster for the whole area, but there are seam lines where the rasters came together that didn't perfectly line up (I'm assuming this is because of the flt conversion), and these pixels recieved the "NoData" value (they are gaps in-between the stiched rasters). I'm trying to shrink these NoData value pixels out, but I'm having trouble finding a tool that lets me do it. The shrink tool in Toolbox only works for integer raster data. Any ideas?
