I have generated DEMs (bare earth) from Lidar data. For computational reasons, I have processed via ArcGis the lidar files in chunks, so I came up with different single DEMs.
After, I used "Mosaic to New Raster" tool, and created a single DEM raster.
I noticed that there are some gaps (lines) along the junctions between the original single DEM rasters (from which I got the single huge raster).
I tried this function in the raster calculator:
Con(IsNull("raster"), FocalStatistics("raster", NbrRectangle(5,5, "CELL"), "MEAN"), "raster")
where "raster" is the name of the single huge DEM.
The problem is that the gaps are still there. Any suggestion?
