An example of a conformal projection is the Transverse Mercator projection, which is used extensively around the world as a basis for grid coordinates and is therefore treated in more detail here. Hence they are essential for the generation of navigational charts, meteorological charts and topographic maps. Conformal maps therefore allow the analysis, control or recording of motion and angular relationships. On a conformal map, meridians and parallels intersect at right angles, and the scale at any point on the map is the same in any direction, although it will vary from point to point. in order to investigate the global or regional distribution of wheat growing areas, an equal-area map is required to consistently represent the size of each area while considerable distortions in the shape and position of these areas may be tolerated. The type of projection chosen is therefore dependent on the extent, scale and intended purpose of the map, e.g. However, some distortion will always remain. Thus it is possible to eliminate certain distortions at the expense of others or to minimise all types of distortions. the preservation of shape locally (conformal projection), scale (equidistant projection) or area (equal-area projection). A multitude of projections has been developed in order to satisfy certain cartographic properties, i.e.

should be apparent that it will be impossible to convert a 3D surface into a 2D surface without any distortions.
