Urchin Tracking Module (UTM) parameters are five variants of URL parameters used by marketers to track the effectiveness of online marketing campaigns across traffic sources and publishing media. They were introduced by Google Analytics ' predecessor Urchin and, consequently, are supported out of the box by Google Analytics.
Urchin Tracking Module parameters, used in Urchin, a Web analytics package that served as the base for Google Analytics and other analytics; Usability testing method, in interaction design; Unbounded transactional memory, transactional memory without bounds on transaction size or time
A position representation is a set of parameters used to express a position relative to a reference frame. When representing positions relative to the Earth, it is often most convenient to represent vertical position (height or depth) separately, and to use some other parameters to represent horizontal position. There are also several ...
A query string is a part of a uniform resource locator that assigns values to specified parameters.A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
This system is commonly used to track the orbits of satellites, because they are based on the center of mass. Thus, this is the internal coordinate system used by Satellite navigation systems such as GPS to compute locations using multilateration. Projected coordinate system (or planar, grid) Layout of a UTM coordinate system.
The set of parameters can vary based on the type of project and the conventions chosen for the projection. For the transverse Mercator projection used in UTM, the parameters associated are the latitude and longitude of the natural origin, the false northing and false easting, and an overall scale factor. [7]
Near the central meridian (Greenwich in the above example) the projection has low distortion and the shapes of Africa, western Europe, the British Isles, Greenland, and Antarctica compare favourably with a globe. The central regions of the transverse projections on sphere and ellipsoid are indistinguishable on the small-scale projections shown ...
When two cells in the Voronoi diagram share a boundary, it is a line segment, ray, or line, consisting of all the points in the plane that are equidistant to their two nearest sites. The vertices of the diagram, where three or more of these boundaries meet, are the points that have three or more equally distant nearest sites.
