Global Mapper

Global Mapper is more than just a viewer capable of displaying the most popular raster, elevation  and vector datasets. It converts, edits,   prints, tracks GPS and allows you to utilize GIS functionality on your  datasets in one low-cost and easy-to-use software package. 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) 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 data in true 3D with  any loaded raster imagery and vector data draped on top of it!
