Google maps

Google Maps is a web mapping service application and technology provided by Google, that powers many map-based services, including the Google Maps website, Google Ride Finder, Google Transit,and maps embedded on third-party websites via the Google Maps API. It offers street maps, a route planner for traveling by foot, car, bike (beta), or with public transportation and a locator for urban businesses in numerous countries around the world. Google Maps satellite images are not updated in real time, but rather they are several months or years old.
Google Maps uses a close variant of the Mercator projection, so it cannot show areas around the poles. A related product is Google Earth, a stand-alone program which offers more globe-viewing features, including showing polar areas.


Satellite view

Google Maps provides high-resolution aerial or satellite images for most urban areas all over the world. Most of the world's current satellite imagery is over 5 years old and updated infrequently, resulting in not showing the newer features and updates that have been made to various infrastructures. Various governments have complained about the potential for terrorists to use the satellite images in planning attacks. Google has blurred some areas for security (mostly in the United States),previously the United States Capitol, the White House, and the U.S. Naval Observatory area (where the official residence of the Vice President is located). Other well-known government installations, including Area 51 in the Nevada desert, are visible.

Not all areas on satellite images are covered in the same resolution; less populated areas usually get less detail. With the introduction of an easily pannable and searchable mapping and satellite imagery tool, Google's mapping engine prompted a surge of interest in satellite imagery. Sites were established to feature satellite images of interesting natural and man-made landmarks, including such novelties as "large type" writing visible in the imagery, as well as famous stadiums and unique geological formations.Although Google uses the word satellite, most of the high-resolution imagery of cities is aerial photography taken from aircraft flying at 800–1500 feet rather than from satellites; while most other imagery is in fact from satellites.

This is a my home by satellite view.
