Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Version 2.0 of Google Maps Mobile was announced at the end of 2007, with a stand out My Location feature to find the user's location using the cell towers, without needing GPS. [ 198 ] [ 199 ] [ 200 ] In September 2008, Google Maps was released for and preloaded on Google's own new platform Android.
Radius = zenith distance: zd [nm] = 60 ⋅ (90 - Ho) (aka co-altitude of Ho) As the circles used for navigation generally have a radius of thousands of miles, a segment a few tens of miles long closely approximates a straight line, as described in Sumner's original use of the method.
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length.. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.
Earth radius (denoted as R 🜨 or R E) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).
In cartography, a locator map, or just a locator, is typically a simple map used to show the location of a particular geographic region within its larger and presumably more familiar context. Depending on the needs of the cartographer, this type of map can be used on its own or as an inset or addition to a larger map.
The following is a timeline for Google Street View, a technology implemented in Google Maps and Google Earth that provides ground-level interactive panoramas of cities. The service was first introduced in the United States on May 25, 2007, and initially covered only five cities: San Francisco, Las Vegas, Denver, Miami, and New York City.
Maps Beta can recognize city, province, and country names, and provide a small-scale map or satellite views. Right click to set waypoint: an origin, destination, or midpoint can be set by right-clicking on the desired location on the map. Draggable markers: Any marker can be dragged to the 'Get Map' text entry area to add that location to a route.
