EXPORT_ELEVATION
Global Mapper User's Manual
The EXPORT_ELEVATION command exports all currently loaded elevation data to a file. The following
parameters are supported by the command.
• FILENAME - full path to file to save the data to
• TYPE - type of elevation file we're exporting to
♦ ARCASCIIGRID - export an Arc ASCII Grid format file.
♦ BIL - export to a BIL format file (simple binary format with header).
♦ BT - export to a BT (Binary Terrain) format grid file.
♦ DTED - export to DTED format grid files.
♦ DXF_3DFACE - export a DXF 3D face format file.
♦ DXF_MESH - export a 3D DXF mesh format file.
♦ DXF_POINT - export a 3D DXF point format file.
♦ ERDAS - export to an Erdas Imagine IMG format file.
♦ FBX - export to Open Flight FBX format file.
♦ FLOATGRID - export a Float/Grid format file.
♦ GEOSOFT_GRID - export to a Geosoft grid format file.
♦ GEOTIFF - export to a GeoTIFF format file.
♦ GLOBAL_MAPPER_GRID - export to a Global Mapper Grid format file.
♦ GRAVSOFT_GRID - export to a Gravsoft Grid format file.
♦ HF2 - export to a HF2/HFZ format file.
♦ IDRISI_RASTER - export to an Idrisi elevation format file.
♦ LEVELLER_HF - export to a Leveller heightfield file.
♦ LIDAR_LAS - export to a Lidar LAS file.
♦ MAPMAKERTERRAIN - export to a MapMaker Terrain format file.
♦ ROCKWORKS_GRID - export to a RockWorks Grid format file.
♦ STL - export to a STL format file
♦ SURFERGRID - export to a Surfer Grid format file. The FORMAT parameter specifies
whether it is an ASCII or binary format Surfer Grid file.
♦ TERRAGEN - export to a Terragen terrain file.
♦ USGS_DEM - export to a native format USGS DEM file.
♦ VRML - export to a VRML file.
♦ VULCAN_3D - export to a Vulcan3D triangulation file.
♦ XYZ_GRID - export to a XYZ Grid file.
• ELEV_UNITS - specify elevation units to use in export
♦ FEET - export in US feet
♦ DECIFEET - export in 10ths of US feet
♦ METERS - export in meters
♦ DECIMETERS - export in 10ths of meters
♦ CENTIMETERS - export in centimeters
• SPATIAL_RES - specifies spatial resolution. Defaults to the minimum spatial resolution of all loaded
data if not specified. Should be formatted as x_resolution,y_resolution. The units are the units of the
current global projection. For example, if UTM was the current global projection and you wanted to
export at 30 meter spacing, the parameter/value pair would look like SPATIAL_RES=30.0,30.0.
• SPATIAL_RES_METERS - specifies spatial resolution to use in meters. The value in meters will
automatically be converted to the curent view/export projection units. For example, to do an export at
2.0 meter spacing (or as close as you can get to that in the current units), use
SPATIAL_RES_METERS=2.0, or to do an export at 1.0 meters in X by 1.5 meters in Y, use
SPATIAL_RES_METERS="1.0,1.5".
