If you are serious about making maps, then you need Global Mapper. Why? Because Global Mapper is an easy-to-use and powerful mapping program that has an amazing ability to display, convert, edit and print the most image, elevation and vector datasets.
Global Mapper also includes the ability to access and directly download the entire TerraServer-USA database of USGS satellite imagery and topographic maps free-of-charge as well as the ability to easily access WMS data sources, including built-in access to elevation data and color imagery for the entire world. Do you want to view elevation data in true 3D? Would you like to do that with any loaded raster imagery and vector data draped on top of it? Then you need Global Mapper!
