Various Map Projections. All Map Projections Different projections are developed for different purposes The slight differences in coordinate assignation between different datums is not a concern for world maps or those of large regions, where such differences are reduced to imperceptibility.

Different map projections serve different mapping needs A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections
Types of Map Projections Lovell Johns
The choice of a map projection for a map depends on the purpose for which the map will be used, the area being mapped, and the map's scale Different datums assign slightly different coordinates to the same location, so in large scale maps, such as those from national mapping systems, it is important to match the datum to the projection Pseudoconic projection is one of the oldest map types and although they were used by Ptolemy, they are seldom seen today

Different Types Of Map Projections. Map projections are created using mathematical formulas Map projections can generally be categorized into three main types: cylindrical, conical, and planar
