Your data files can be loaded as layers, for example a Digital Elevation Model (DEM) can be loaded with a scanned topographical map to create a 3D sun shaded view of the map. A digital aerial image can be draped on the surface together with vector contour mapping to create a stunning and informative graphic. The results can be printed, or the workspace can be exported to a high resolution raster image for use in a presentation or report.

Have you ever received a dataset that does not match the projection of your current project? Simply load the dataset into Global Mapper change the projection and save the file to match your coordinate system. If the dataset is larger than the area you are interested in, export the data using the crop feature and change the projection and format of the data at the same time.

Global Mapper is more than just a utility; it has built in functionality for distance and area calculations, elevation querying and line of sight calculations as well as advanced capabilities like contour generation from surface data. Repetitive tasks can be accomplished using the built in scripting language.

• Supports viewing of most of the popular data formats, including DLG-O, DRG, DOQ, DEM, DXF, SDTS DLG, SDTS DEM, ECW, MrSID, ESRI Shapefiles, E00, GTOPO30, TerrainBase, ETOPO2 etc.
• Support the latest DEM and SDTS DEM formats, including decimeter DEMs.
• Crop, reproject, and merge any combination of raster data, including DRGs.
• EXPORT SUPPORT! You can export both vector, raster, and elevation data to a variety of formats (see below). You can merge any combination of data sets, regardless of source scale, type, and projection. See below for a list of supported export types.
  • Vector Data (i.e. DLG's, Shapefiles, etc.)
    • USGS DLG-O format
    • AutoCAD DXF format
    • ESRI Shapefile format
    • XYZ ASCII format
  • Raster Data (i.e. DRG's, DOQ's, etc.)
    • GeoTIFF format
  • Elevation Data (i.e. DEM's, etc.)
    • USGS DEM format
    • GeoTIFF DEM format
    • Surfer Grid (ASCII and binary) formats
    • XYZ ASCII Grid format
    • Arc ASCII Grid format
    • 3D DXF Mesh format
• CONTOUR GENERATION! You can create contours for any combination of elevation data. You can also specify the contour interval to use. The generated contour data can then be exported to DXF (as 3D polylines), DLG-O, or ESRI Shapefile formats.
• Advanced screen capture. You can capture the contents of the screen to a BMP, JPG, or (Geo)TIFF file of user-specified resolution.
• Batch conversion of SDTS DEM data files to native format USGS DEM data files.
• Batch conversion of SDTS DLG data to AutoCAD DXF files and ESRI Shapefiles.
• Auto-clip collar for DRG's. You can now have the collar of USGS DRG files automatically clipped off. This allows you to seamlessly view a collection of adjacent DRG files.
• Supports opening SDTS DLG and SDTS DEM files directly from .tar.gz archives. This saves the major headache of decompressing each SDTS transfer into a separate directory.
• 3D Path Profiling and Line of Sight (LOS) capabilities, including receiver/transmitter heights, minimum clearance, and earth curvature options.
• Supports opening DLG-O and DEM files directly from gzipped archives. This means that you can save space and hassle by not having to decompress the data after you download it.
• Slide over text. When you move your cursor around the screen you'll get a description of the nearest feature automatically displayed in the status bar.
• Supports keyboard navigation. You can pan about with the arrow keys and zoom in/out with the page up/page down keys.
• Search by name for all loaded vector data.
• And more!
