Aug-23-01, 03:52 PM (EST) "Correct Elevation?" Can anyone explain why a single quad .XYZ file with only positive elevation produces negative elevation when the .XYZ file converted to MSTS tiles using the JohnCS extractor.
Basically 0 m height is translated to -19 m height
I plotted the .XYZ file below just to show there is no negative elevation. Alert Edit | Reply | Reply With Quote | Top

I have seen results, which supports that.
