Grid Data Files for France
Concept Procedure
 
 
 

To set up a new grid data file for France

  1. When you obtain a new grid data file, copy it into the appropriate folder under the Autodesk shared coordinate system folder, by default C:\Documents and Settings\All Users\Application Data\Autodesk\Geospatial Coordinate Systems.
  2. Open RgfToNtf.gdc in any text editor or word processor that can produce an ASCII file, such as Notepad or Wordpad.
    NoteBack up GDC files before you edit them, so you can restore them to their previous state, if necessary.
  3. Edit the file to point to the name and location of your new grid data file.
  4. Make other changes needed, such as rearranging or replacing grid data files, changing the fallback datum definition, or adding comments.
