Traverse is a method in the field of surveying to establish control networks. [1] It is also used in geodesy. Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. Connected survey lines form the framework and the directions and ...

Google Maps – mapping service that indexes streets and displays satellite and street-level imagery, providing directions and local business search. Google My Maps – a social custom map making tool based on Google Maps. Google Earth – virtual 3D globe that uses satellite imagery, aerial photography, GIS from Google's repository.
A point P has coordinates (x, y) with respect to the original system and coordinates (x′, y′) with respect to the new system. In the new coordinate system, the point P will appear to have been rotated in the opposite direction, that is, clockwise through the angle . A rotation of axes in more than two dimensions is defined similarly.
Triangulation of Kodiak Island in Alaska in 1929. In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration.
A control point ( CP, also control and checkpoint) is a marked waypoint used in orienteering and related sports such as rogaining and adventure racing. It is located in the competition area; marked both on an orienteering map and in the terrain, and described on a control description sheet. The control point must be identifiable on the map and ...
U.S. National Geodetic Survey. The National Geodetic Survey ( NGS) is a United States federal agency based in Washington, D.C. that defines and manages a national coordinate system, providing the foundation for transportation and communication, mapping and charting, and a large number of science and engineering applications.
A geodetic control network is a network, often of triangles, that are measured precisely by techniques of control surveying, such as terrestrial surveying or satellite geodesy. It is also known as a geodetic network, reference network, control point network, or simply control network . A geodetic control network consists of stable, identifiable ...
