Google has worked with Chinese location-based service provider AutoNavi since 2006 to source its maps in China. [44] Google uses GCJ-02 data for the street map, but does not shift the satellite imagery layer, which continues to use WGS-84 coordinates, [ 45 ] with the benefit that WGS-84 positions can still be overlaid correctly on the satellite ...
This is a list of satellite map images with missing or unclear data. Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as ...
Google Maps' location tracking is regarded by some as a threat to users' privacy, with Dylan Tweney of VentureBeat writing in August 2014 that "Google is probably logging your location, step by step, via Google Maps", and linked users to Google's location history map, which "lets you see the path you've traced for any given day that your ...

Closed prisons. The following prisons are no longer in operation by the Department of Corrections. [2][3] McNeil Island was opened in 1875 by the U.S. government as a federal penitentiary. WSDOC signed a lease in 1981 to use the island, which was officially deeded to the State of Washington in 1984. [5]
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [1][2] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [1] In a broader sense, one may consider such a system ...
Those for any particular geographical area can be easily calculated by comparing the GPS-measured position to a known surveyed location. This correction is also valid for other receivers in the same general location. Several systems send this information over radio or other links to allow L1-only receivers to make ionospheric corrections.
Geodesy. The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
