The Export CSV command allows the user to export any loaded point data sets to a CSV (Comma Separated File) file.
When selected, the command displays the CSV Export Options dialog which allows the user to set up the export. The dialog consists of an Options panel which allows the user to set up options such as what to use as the delimiter, the precision to store in the file, and whether or not to include an elevation attribute for each point as well as whether to include the name of each column in the file as the first row in the file. There is also an Export Bounds panel which allows the user to set up the portion of the loaded point data they wish to export.
If you choose to Export Separate Lat/Lon Coordinates for Each Point, the LATITUDE and LONGITUDE attributes that are created will use the current Position Display Format setting on the General tab of the Configuration dialog for formatting those values if you also have the option checked to Format lat/lon coordinates with Position Display Format.
ADVANCED USERS - In Global Mapper v11.02 and later you can customize the number of decimal digits written out for the X and Y coordinates for a CSV export by creating a DWORD registry key 'HKEY_CURRENT_USER\Software\Global Mapper\ASCIIExportCoordPrecision'. For example, set this value to 6 to get 6 decimal digits for each X, Y, and Z coordinate.
