A.planar projection--------------Map with the North or South Pole at its center. Landforms are distorted toward the equator.
Planar projections project map data onto a level surface. In spite of the fact that the purpose of contact might be any point on the world's surface, the north and south poles are the most widely recognized contact focuses for most GIS databases. Different areas are utilized principally for particular applications, such a route or locational inset maps.
At the point when the plane contacts the earth at either the north or south poles, longitude queues join at the purpose of contact and emanate outward from the post at their actual edge like the spokes on a wheel, the separation between them expanding as the separation from the contact point increments.
B.cylindrical projection----------Lines of latitude and lines of longitude are perpendicular
A cylindrical projection can be envisioned in its least complex frame as a chamber that has been folded over a globe at the equator. The points on the round framework are exchanged to the chamber which is then unfurled into a level plane. The equator is the "ordinary perspective" or perspective for these projections. This group of projections are normally used to represents the whole world.
One of the general characteristic is lines of latitude and longitude are parallel intersecting at 90 degrees.
