Mercator projection mercator projection n a cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear. The universal grids and the transverse mercator and polar stereographic map projections x map projection plane abscissa distance on the horizontal axis. Transverse mercator¶ the transverse mercator projection in its various forms is the most widely used projected coordinate system for world topographical and offshore mapping. This conformal projection is the transverse form of the mercator projection and is also known as the gauss-krueger projection it is not equal area. Transverse mercator projection central meridian is selected by the map maker and touches the cylinder maps using the projection can show the whole earth, but directions, distances, and areas are reasonably accurate only within 15° of the central meridian.
Wisconsin coordinate reference systems figure 2: the transverse mercator projection figure 3: shifting a rectangular coordinate system’s origin. 23 what are map projections like the universal transverse mercator (utm) as it is in the transverse mercator projection). Definitions of transverse mercator projection, synonyms, antonyms, derivatives of transverse mercator projection, analogical dictionary of transverse mercator projection (english). Map projections a map projection is a means of projecting the spherical earth the bng is a grid coordinate system based on the transverse mercator projection.
The transverse mercator map projection is an adaptation of the standard mercator projectionthe transverse version is widely used in national and international mapping systems around the world, including the utm. Transverse mercator projection the familiar mercator map is based on the great circle of the equator any great circle can be taken as the basis. 5 shape of the earth, constants, formulae and methods i introduction this pamphlet supersedes both the hmso booklet constants formulae and methods used in the transverse mercator projection, which is out. There is also a transverse form of the mercator projection, illustrated above (deetz and adams 1934, snyder 1987) it is given by the equations.
A facility for converting latitude/longitude co-ordinates to co-ordinates in metres on a transverse mercator projection an excel workbook is also available on this page to carry out bulk conversions. A conformal map projection in which the regular mercator projection is rotated (transversed) 90° in azimuth, the central meridian corresponding to the line which represents the equator on the regular mercator the characteristics as to scale are identical to those of the regular mercator, except. This page is a web resource for the paper charles f f karney, transverse mercator with an accuracy of a few nanometers, j geodesy 85(8), 475–485 (aug 2011). Utm grid zones of the world compiled by alan morton there are 60 longitudinal projection zones numbered 1 to 60 starting at 180°w transverse mercator calculator.
Ticular projection for which they are designed the universal transverse mercator grid the national imagery and mapping agency (nima) (formerly the defense.
Figure 2221 a mercator projection of the world, showing the 60 utm coordinate system zones, each divided into north and south halves at the equator. What are the characteristics and uses of the mercator electronic maps we are all familiar with actually use transverse mercator projection and they.
Decision support system for map projections of small scale data transverse mercator usage usage: since the regular mercator projection has little error close to the equator, it has been found very useful in the transverse form, with the equator of the projection rotated 90º to coincide with the desired central meridian. Mercator projection the mercator projection is formed by imagining a cylinder wrapped around the earth and tangent at the equator the point of projection is from the center of the earth. Transverse mercator projection¶ the transverse aspect of the mercator projection the globe is first rotated so the central meridian becomes the “equator”, and then the normal mercator projection is applied. Maps and cartography: map projections the transverse mercator projection is a cylindrical projection often used to portray areas with larger north-.Download
