Blue Marble's first software product, the Geographic Calculator, [2] was developed in 1992 and released in 1993. The Geographic Calculator is a coordinate conversion library with a database of coordinate mathematical objects including projections, coordinate systems, datums, ellipsoids, linear and angular units. The tool is primarily used to ...
Center the screen on your location by double-clicking on it, then use the View in Google Maps button at the top (Google Earth 4.1 and newer). This will open Google Maps within Google Earth. You can see the center coordinates in decimal format in the address bar, but unfortunately you cannot copy them directly.
A coordinate system conversion is a conversion from one coordinate system to another, with both coordinate systems based on the same geodetic datum. Common conversion tasks include conversion between geodetic and earth-centered, earth-fixed coordinates and conversion from one type of map projection to another.
The standard style for OpenStreetMap, like most Web maps, uses the Web Mercator projection. Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator [1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted ...
It was developed at Google's Zürich engineering office, [2] and released late October 2014. [3] Location codes created by the OLC system are referred to as "plus codes". Open Location Code is a way of encoding location into a form that is easier to use than showing coordinates in the usual form of latitude and longitude. Plus codes are ...
The maps roughly implies a coordinate reference system, but does not clearly specify one (unlike Earth's WGS84). Since the template defaults to east longitude, the |W| direction must be specified for globes that measure longitude westward. For celestial coordinates, use {} instead.
The Google Maps apps for iOS and Android have many of the same features, including turn-by-turn navigation, street view, and public transit information. [212] [213] Turn-by-turn navigation was originally announced by Google as a separate beta testing app exclusive to Android 2.0 devices in October 2009.
The Gauss–Krüger coordinate system used in Germany normally refers to the Bessel ellipsoid. A further datum of interest was ED50 (European Datum 1950) based on the Hayford ellipsoid. ED50 was part of the fundamentals of the NATO coordinates up to the 1980s, and many national coordinate systems of Gauss–Krüger are defined by ED50.
