The Export Zmap Plus Grid File command allows the user to export any loaded elevation grid data sets to a Zmap Plus Grid format file.
When selected, the command displays the Zmap Plus 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 grid spacing and vertical units and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
