TerraExplorer is a powerful exploration tool that allows you to combine satellite imagery and other geographical information for exploring a certain area. The program can also annotate, analyze and publish the information from the 3D environment.
It features a simple interface that provides access to the main features in a ribbon menu. The user can explore the map, zoom to the house level, measure distances and customize the environment by selecting the visible data layers.
Note: The free version of the application allows you to navigate and analyze the 3D world environments. If you want to import your own raster layers, edit the landscape or publish the images you need to purchase a paid version.
