Optional thinned grid formats
When PhotoSat completes mapping projects over large areas, the file size can be enormous. To make it to easier open and work with large files, we offer thinned grid formats.
With thinned grids, we remove adjacent points if they have the same elevation. This eliminates redundancy in the data set. The remaining elevation points still form an accurate data set, but the result is a smaller file size.
Thinned grids are especially useful for terrain with low grade slopes, since mapping this type of terrain usually produces more points with the exact same elevation.
