Global Mapper

Global Mapper also includes the ability to directly access multiple online sources of imagery, topographic maps, and gridded terrain data. This includes access to worldwide high resolution color imagery from DigitalGlobe (watermarked access for free), detailed street maps from, and access to the entire TerraServer-USA/ database of USGS satellite imagery and topographic maps free-of-charge. Global Mapper also has the ability to easily access WMS data sources, including built-in access to elevation data and color imagery for the entire world, and to view elevation and vector data in true 3D with any loaded data draped on top of it!

Provides direct access to DigitalGlobe high resolution color imagery and detailed street maps 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 Landsat imagery free-of-charge within the application!
Supports true 3D viewing of loaded elevation and 3D vector data including draping of any loaded imagery and vector data over the 3D surface.
Crop, reproject, and merge/mosaic any combination of raster data and elevation data, including DRGs. You can also crop data to an area feature. Data will automatically mosaic into the correct location relative to each other using positioning information associated with the data.
GeoPDF® SUPPORT! You can import GeoPDF® files and export any collection of loaded data to new Geo-enabled PDF files, making your data accessible to any user without requiring them to have any mapping knowledge.
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, buffers around existing features, and concentric range rings can be easily created as well. You can also input features via a series of distance/bearing/COGO coordinates.
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! With supported devices (such as the RavTrack GPS Transponders from RaveonTech) you can even track multiple GPS devices in order to perform fleet management functions. You can also send any loaded data to comaptible Garmin GPS devices (like Oregon and Colorado devices), thus allowing you to easily view imagery and other data on your handheld Garmin device.
PROJECTION/DATUM SUPPORT - Global Mapper supports accurate conversions between a large list of projection systems and datums. NAD27 and NAD83 HPGN/HARN 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. Get more details about formats!

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 (i.e. LIDAR) 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.
Multi-Spectral Support! With Gloabl Mapper you can easily load and display imagery with more than 3 bands of data and configure which bands are used for the red, green, and blue color channels. You can also export your multi-band imagery to new multi-band GeoTIFF files and configure exactly what is the input for each exported band.
Support 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.
WATERSHED DELINEATION! You can automatically determine stream flow and delineate the watersheds for those streams based on any loaded terrain surface data. The generated line and area features can then be exported to any support vector format, such as Shapefiles.
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.
Virtual Earth Support! Any loaded data can be exported to JPG or PNG image tiles setup for immediate display using Microsoft\'s Virtual Earth interface 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.
Batch conversion of almost any input data data files to any compatible export type.
Automatic collar removal for DRG, DOQQ, BSB, GeoPDF®, and other formats. You can now have the collar of USGS DRG, DOQQ, BSB (marine chart), and GeoPDF® files automatically clipped off. This allows you to seamlessly view a collection of adjacent files. Manual collar cropping is also supported.
Supports opening SDTS DLG, SDTS DEM, and most other file types directly from .tar.gz and .zip archives. This saves the major headache of decompressing each SDTS transfer into a separate directory.
Comprehensive view shed analysis using loaded elevation grid data from a user-specified location, transmitter height, and radius.
3D Path Profiling and Line of Sight (LOS) capabilities, including receiver/transmitter heights, minimum clearance (including Fresnel zone analysis), and earth curvature options.
Advanced measurement capabilities, including multi-segment path lengths and headings, enclosed area, and cut-and-fill volume calculations either along a path or within an enclosed area.
Supports the easy creation of geological features, like strike-and-dip points, with attributes like azimuth and dip displayed in a visual manner.
Advanced drawing capabilities, including custom area fill styles and point symbols, dozens of supported line styles, and line and font sizes scaled to an actual size on the ground or a fixed number of display pixels.
Ability to link vector feature attributes to web sites or files.
Support the latest DEM and SDTS DEM formats, including decimeter DEMs.
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 and edit load vector data by name, attribute value, or description.
Load and display JPG images with embedded EXIF positioning data at the location that the image was taken with your EXIF-compatible camera.
