Open Printable/Searchable Copy - Global Mapper

Note: Only registered users of Global Mapper are able to export data to any format.
Export JPEG2000 Elevation Command
The Export JPEG2000 Elevation command allows the user to export any loaded elevation grid data sets to a
32-bit JPEG2000 format elevation grid format file, providing excellent (but lossy) compression of gridded
elevation data sets.
When selected, the command displays the JPEG2000 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 Gridding panel, and an Export Bounds panel which allows the user to set up the portion
of the loaded data they wish to export.

Export KML/KMZ Command
Global Mapper User's Manual
The Export KML/KMZ command allows the user to export any loaded raster, vector, and elevation grid data
sets to a KML/KMZ format file for display in Google Earth. If you are wanting to export a vector KML/KMZ
file from loaded vector data, use the File->Export Vector Data->Export KML/KMZ menu command instead.
When selected, the command displays the KML/KMZ Export Options dialog (pictured below) which allows
the user to setup the export. The dialog consists of a KML/KMZ Options panel, 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.
The KML/KMZ Options panel allows the user to set up the target image format for storage and the sample
spacing, as well as other options such as whether to store all of the resulting files in a KMZ file
(recommended) and whether or not to render and save loaded vector data. The Visibility Range/Fading Setup
section allows advanced users to control the minLodPixels, maxLodPixels, minFadeExtent, and
maxFadeExtent values used in the exported file to control when (i.e. what zoom level) the data will be
displayed and also if and how to fade the data.
There is also an option to automatically grid the data on export (this creates what is known as a
SuperOverlay). Enabling this option allows very large quantities of data to be efficiently viewed using Google
Earth. When using this option you can also control the tile size to use when creating the super overlays. For
very large exports the larger sizes (1024x1024 or 2048x2048) are recommended.
