Google Earth Maps
Google Earth is by far the most powerful scouting tool for DIY hunters. These maps can zoom into any place on earth and views up to date satellite imagery of fields, tree lines, fence rows and bodies of water. The hunter can also pan or tilt the earth to check out the terrain of the land which includes aerials or ridges, draws, and ravines.
Google Earth is a free mapping tool.
