The Export NGC Geoid ASCII Grid command allows the user to export any loaded elevation grid data sets to an NGC Geoid ASCII Grid file.
When selected, the command displays the NGC Geoid ASCII Grid Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing and format, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
