Red circles reveal the scale distortion introduced during the transformation from geographic to projected plane coordinates. The convergence angle between projected meridians and the x constant grid lines is no longer zero except on the equator so that a grid bearing must be corrected to obtain an azimuth from true north.

The precise Redfearn series, although of low order, cannot be disregarded as they are still enshrined in Utm projection quasi-legal definitions of OSGB and UTM etc. Note that while South America is distorted greatly the island of Ceylon is small enough to be reasonably shaped although it is far from the central meridian.

As you can imagine, you can't flatten a globe without breaking or tearing it somehow. Large scale maps usually include the coordinates of the adjacent zones each zone is extended into its neighbor when a zone boundary falls within the map, that is more than one zone or portion of are shown on the map.

Gridlines or ticks near the corners of the map are designated with full coordinate values. The thicker red line on the cylinder and the map is the standard line along which scale distortion is zero.

The abbreviated grid reference is: A list is given in Appendix A. In the southern hemisphere the northing values range from 10,m at the equator to approximately m at the 80th south parallel. If you were to plot the points representing the two cities on a map, ignoring the fact that the two zones are two distinct coordinate systems, Philadelphia would appear to the west of Pittsburgh.

Prior to the development of the Universal Transverse Mercator coordinate system, several European nations demonstrated the utility of grid-based conformal maps by mapping their territory during the interwar period. Vertical grid lines on map are used to find easting while horizontal grid lines are used to find northing of a point; similarly grid lines can be used to help locate a point with known coordinates.

On the sphere it depends on both latitude and longitude.

There are no conversion between formats, such as between decimal and DMS. The zone is always written first, followed by the latitude band. Distortion is zero, of course, along the standard lines.

That is each grid square is m xm. Distortion is small near the central meridian and the projection particularly in its ellipsoidal form is suitable for accurate mapping of narrow regions.OVERVIEWUTM coordinates are based on a family of Transverse Mercator map projections (two for each UTM zone, with one for each N/S hemisphere).

The earth is divided into 60 zones, each 6Â° wide in longitude (with the exception of a few non-standard-width zones for Svalbard and southwest of. The Universal Transverse Mercator (UTM) conformal projection uses a 2-dimensional Cartesian coordinate system to give locations on the surface of the Earth.

Like the traditional method of latitude and longitude, it is a horizontal position representation, i.e. it is used to identify locations on the Earth independently of vertical position. The UTM projection is commonly used in research because it tends to be more locally accurate, and furthermore, it has attributes that make the estimating distance easy and.

UTM - Universal Transverse Mercator UTM Projection. As the name suggests, the Universal Transverse Mercator projection is based on the cylindrical Transverse Mercator projection.

The cylinder in the Transverse Mercator projection is tangent along a meridian (line of longitude) or it is secant, in which case it cuts through the earth at two standard meridians.

Universal Transverse Mercator (UTM) coordinate system is a standard set of map projections with a central meridian for each six-degree wide UTM zone. The transverse Mercator map projection is an adaptation of the standard Mercator projection which flips the cylinder 90 degrees (transverse).

The transverse Mercator map projection is an adaptation of the standard Mercator wsimarketing4theweb.com transverse version is widely used in national and international mapping systems around the world, including the wsimarketing4theweb.com paired with a suitable geodetic datum, the transverse Mercator delivers high accuracy in zones less than a few degrees in east-west extent.
