i have a group of raster files in .tif format that I want to mosaic together into one .tif.
I've noticed that I get data gaps along the seams when I do Mosaic to New Raster() on my home computer (ArcMap 10.1). Also, these data gaps are not necessarily where there is no data because when I display the original .tif files, there is coverage where the final mosaic-ed raster shows "no data" values. There should be some gaps because the original rasters do not completely overlap, but there is more coverage than what is shown here as gaps. Here is a screen shot of the mosaic-ed raster with the data gaps:
Then, when I do the same operation on the same rasters in the same order, but on a different computer (ArcMap 10), there are no gaps at all. Here is a screen shot of the mosiac-ed raster in the same region as above:
Ideally, I would like a final single raster with no data gaps so I would like to use the no gap raster, but is it reliable? I've read that Mosaic to New Raster does not interpolate the no data areas, so what could be going on? How do I know which final layer is reliable?
