Global Mapper 10 supports accurate conversions between a large list of projection systems and datums.

Global Mapper 10 supports viewing of dozens of the most common data formats: DLG-O, DRG, DOQ, DEM, DGN, DTED, DWG, DXF, SDTS DLG, SDTS DEM, ECW, MrSID, ESRI Shapefiles, E00, JPEG2000, CADRG/CIB, GeoTIFF, KML/KMZ, Lidar LAS, Arc Grid, Tiger/Line And many, many more!

Provides direct access to Digital Globe, GlobeXplorer, and AirPhotoUSA high resolution color satellite imagery for the entire world from within the application!

Provides direct access to the complete TerraServer-USA satellite imagery and topographic map archive for the entire US free-of-charge within the application!

Provides easy, direct access to WMS data sources, including built-in access to the complete 30-m NED database, the 3-arc second world SRTM database, and color global imagery free-of-charge within the application!

Global Mapper 10 supports true 3D viewing of loaded elevation data including draping of any loaded imagery and vector data over the 3D surface.

Crop, reproject, and merge any combination of raster data and elevation data, including DRGs. You can also crop data to an area feature.

DIGITIZING SUPPORT! You can digitize new vector (area, line, and point) features by drawing them with the mouse. You can also edit existing vector features. Newly created and editing features can be saved to any of the supported export formats. In addition, shapes like rectangles, circles, ellipses, arcs, and concentric range rings. Global Mapper 10 can be easily drawn as well.

GPS SUPPORT! You can track a compatible GPS device connected to your computer's serial port or USB port in real-time over any loaded data. In addition, you can mark waypoints at the current GPS location and record a tracklog of where your GPS device has been while connected, all seamless with your loaded map data!

PROJECTION/DATUM SUPPORT - Global Mapper 10 supports accurate conversions between a large list of projection systems and datums. NAD27 datum conversions in the US use the NADCON conversion method, and the NTv2 datum conversion method is used for the NAD27 (Canada), AGD66, AGD84, and NZGD49 datums. Custom datum conversions can be easily added in either 3-parameter or 7-parameter form if a required datum transformation is not already supported.

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. You can also breakup your data into a regularly spaced grid on export if you'd like as well.

IMAGE RECTIFICATION! You can graphically rectify (georeference) any JPG, TIFF, or PNG image and save the results to a new fully georeferenced image. Vector data can also have a rectification process applied to it after loading to allow morphing vector data to fit other data sets.

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 any of the supported vector export formats (see previous item for a list).

Automatic triangulation and gridding of 3D point data sets, such as ASCII XYZ files. This allows you to convert a set of elevation samples into a fully gridded data set, which can then be used for contour generation, line of sight analysis, and view shed analysis, among other things. The data can also be exported to any of the supported elevation grid formats, such as USGS DEM.

Global Mapper 10 supports for combining/comparing terrain surfaces, such as DEMs. This allows you to generate a new terrain surface by combining/comparing two loaded terrain surfaces with operations like subtraction (difference), averaging, and min/max. The results can then be exported to any of the supported elevation grid formats, such as USGS DEM.

NASA World Wind Support! Any loaded data can be exported to JPG or PNG image tiles setup for immediate display in NASA's World Wind application. The necessary .xml file is also automatically generated.

Google Maps Support! Any loaded data can be exported to JPG or PNG image tiles setup for immediate display using Google Maps in a web browser. The necessary HTML file is also automatically generated.

Advanced screen capture. You can capture the contents of the screen to a BMP, JPG, PNG, or (Geo)TIFF file of user-specified resolution.
