Open Printable/Searchable Copy - Global Mapper

If the Save Vector Data if Displayed option is checked, any loaded vector data that is configured to show up in
the main display will be saved to the GeoTIFF file (except vertical GeoTIFFs).
If the Generate TFW File option is checked a TIFF world file will be generated with the same name as the
GeoTIFF file with a .tfw extension. The TFW file is used by software that is not capable of reading the
placement of the GeoTIFF file directly from the GeoTIFF header.
If the Interpolate to Fill Small Gaps in Data option is checked, any small areas with missing data will be
filled in by interpolating the surrounding valid data. This is useful for filling small gaps between adjacent tiles
or small holes in elevation data.
If the Generate PRJ File option is checked a describing the projection of the coordinates in the file will
automatically be created
If the ADVANCED: Don't Write GeoTIFF Header option is checked no GeoTIFF tags will be written to the
generated file. This is useful for using things like datum specializations that can't be exactly stored in
GeoTIFF files, so you'd rather just use a PRJ file and not have anything in the GeoTIFF file.
Export Global Mapper Grid Command
The Export Global Mapper Grid command allows the user to export any loaded elevation grid data sets to a
Global Mapper Grid format file. The Global Mapper Grid format is a highly compressed elevation grid format
that loads and draws very quickly and requires very little memory. If you have a choice for what format to
store your gridded elevation data in, we suggest using the Global Mapper Grid format.
When selected, the command displays the Global Mapper 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, a Gridding panel, and an Export Bounds panel which allows the user to set up the
portion of the loaded data they wish to export.
Note: Only registered users of Global Mapper are able to export data to any format.
Export Google Maps Tiles Command
Global Mapper User's Manual
The Export Google Maps Tiles command allows the user to export any loaded datato JPG or PNG files tiled
in the configuration required for display in using the Google Maps interface. This command will create both
the image tiles and a sample HTML file for displaying the data with the Google Maps interface. You can just
load the HTML file into your web browser to view the data once the export is over. You can also customize
the HTML file however you need to.
When you select the command, the Google Maps Export Options dialog (pictured below) appears allowing
you to setup the export. This dialog allows you to specify the display name of the map set in your web
browser, the zoom level setup, the Google Maps API key to use, the format of the imagery, and some
additional options. There is also an Export Bounds panel which allows the user to set up the portion of the
loaded data they wish to export.
