Posted - 26/12/2013 : 15:41:13 Hi; I have a large .ecw file for a georeferentiated collage of low flying aircraft runs over a wilderness area. If I set the units to UTM and then I import location points from Google Earth KMZ´s to OKmap, the locations are accurate, they match.
The problem I have is that at the bottom of the screen where the UTM location is displayed I have two sets of the same UTM location for the cursor, but no altitude.
Thus I cant tell whether I did something wrong in the setup, or the .ecw file is faulty and does not contain the altitude data, or there is somethingw wrong with the software.
Posted - 26/12/2013 : 17:36:08 Use menu "Utilities - Preferences" and go to General page. Set coordinates to "Decimal degrees". This will set the first coordinates in status bar. The second coordinates are set always to alternative projection of the map (if your alternative projection is UTM they will be same value as UTM). To display altitude you should download DEM data files. Use menu DEM - Download DEM files. Check that all data files are already downloaded (green) otherwise press download button. ECW map doesn't contain any altitude data.
