When the GeoTiff files are imported into some software programs, it has been reported that values of –32768 result. This is due to the software failing to identify values of –32768 as pixels with no data. Users can either search for a solution that fixes this or should explore the ASCII files that so far have not presented any similar problems. This problem can be solved by reclassifying (reclassifying –32768 as NO DATA) or querying all pixels with values greater than –32768, and recalculating the grid based only on those regions.
