Global Mapper is more than just a utility; it has built in functionality for distance and area calculations, raster blending, feathering, spectral analysis and contrast adjustment, elevation querying, line of sight calculations, cut-and-fill volume calculations, as well as advanced capabilities like image rectification, contour generation from surface data, view shed analysis (including Fresnel) from surface data, and triangulation and gridding of 3D point data. Repetitive tasks can be accomplished using the built in scripting language or comprehensive batch conversion functionality.
There is not a GIS tool who compares with Global Mapper when you need to manage simultaneously the most variated types of data such as altitude files, vector data and raster or ASCII files with different coordinate and projection systems, all at the same time, and into one of the most simple and user friendly environment you ever seen.
With Global Mapper you can produce ouputs that are impossible to do with other high level products. Global Mapper unveils all the power of your hardware allowing you to manage huge data files with low-performance computers.
Global Mapper has been adopted by the USGS as a standard tool under the name of dlvg32 Pro. So you can have the peace of mind that all the convertion calculations and all the export formats match with the most elevated standards of the industry and they assure you an absolute compatibility when exchanging data with other users or applications
