Cylindrical Projection Let us draw a network of Simple cylindrical Projection for the whole globe on the scale of 1: 400,000,000 spacing meridians and parallels at 30º interval The size of any area on the map is in true proportion to its size on the earth. Such projections can be used to show Preserves true scale from a single point to all other points on the map. The maps that use this property include: UTM projection divides the surface of the Earth into a number of zones, each zone having a 6 degree longitudinal extent, Transverse Mercator projection with a central meridian in the center of the zone. UTM zones extend from 80 degrees South latitude to 84 degrees North latitude. The zones are numbered from west to east. The first zone begins at the International Date Line (180°). The particular transverse Mercator map that is used to represent each zone has its central meridian running north-to-south down the center of the zone. This means that no portion of any particular zone is very far from the central meridian of the transverse Mercator map that is used to depict the zone. Since a Universal Transverse Mercator zone is 6° of longitude wide, no portion of a UTM zone is more than 3° of longitude from the zone’s central meridian. Since the distortion in a transverse Mercator map is relatively low near the map’s central meridian, the result of this close proximity to the map’s central meridian is that the transverse Mercator map used to depict each zone within the coordinate system contains relatively little distortion. Adapted from the report Map Projections of Europe (2001), the table gives an account of the commonly used projection systems. Source.
