Google has recently launched Google Earth, the web search company’s satellite imagery-based mapping product that combines 3D buildings and terrain with mapping capability and search. Based on Keyhole technology, Google Earth enables users to move from space to street level views to find geographic information. Features of Google Earth include free software download, 3D buildings in major cities across the United States, 3D terrain showing mountains, valleys, and canyons around the world, integrated Google Local search and video playback of driving directions.
With Google Earth, users can combine multiple layers of information, such as cross-referencing school districts with address look-ups of available homes, business listings and public transportation, and save their results for later use.
