Global Mapper more than a visualizing instrument, able to display the most usual sets of raster data, elevation or vector. It converts, edits, prints, creates GPS tracks and will allow you to use GIS functions of your data sets, under a software package with an incredible low price and easily to use. The new version 7.xx offers you the possibility of direct accessing the whole TerraServer data base, that contains USGS satellite images and topographic maps and visualizing elevation data in 3D format!

Your data folders can be loaded as layers, for example a Digital Elevation Model can be loaded together with a topographic map, scanned in order to create a 3D representation with lights and shadows of the map. An air digital image can be represented together with a vector map of contours in order to create a spectacular graphic. The results can be printed or exported as raster images of high resolution in order to be used in presentations and reports.

Have you ever received a data set that does not fit, from the point of view of the projection, to your current project? All you have to do is to load the data set in Global Mapper, to change the projection and to save the folder so that it is represented in the same coordinate system. If the data set is bigger than the surface you are interested in, you can export the data using Crop option and you can change the projection and the data format in the same time.

Global Mapper is more than a simple utility program; it has incorporated functions for calculating the distances and surfaces, combinations of bitmap images and contrast adjustments, elevation analysis and calculations of line of sight, and advanced functions like image rectifications, contour set up, view shed on the base of surface data, and triangulations and gridding for 3D data. There can be repetitive processes using the incorporated scripts of the numerous conversion options on portions.
