Grid files

The application allows loading custom grid files for NTv2 coordinate transformations..

Transformation using Grid files

  • Some coordinate transformations (NTv2, etc.) require one or more Grid files in order to be processed. Some of the most commonly used Grid files worldwide are included in the application, but you can see that some others instruct you on where to download Grid file(s) not included with the application (usually a download URL).
  • On the other hand, even if the required Grid file(s) already exist (included as standard in the application, or previously downloaded by the user), the application allows the user to choose alternative Grid file(s) so that he can use more accurate or updated Grid transformations when more appropriate files are available. This custom choice for a Grid file is kept by default for a work session, but will not be memorized when exiting and re-entering the application.
