Map Projection In Geodesy

Map projections and their application to spatial data. Introduction to geodesy and map projections. Provided below is an illustration of the state plane zones in the 48 lower contiguous states of the united states of america.

While determination of the earth’s figure and size is one of the fundamental tasks of geodesy, map projections include the study of spherical or ellipsoidal transformation from the earth’s or another planet’s surface model to a two dimensional representation. A map projection is a systematic representation of all or part of the surface of a round body, especially the earth, on a flat surface. Geodesy, map projections and coordinate systems.

The choice of projection establishes whether people can assume that shapes you draw on the map have any actual geometric correspondence with the actual geometry of the place on the ground.

Geodesy and cartography deal in these aspects of science which are mathematic rich. Geodesy and cartography deal in these aspects of science which are mathematic rich. Attempt to accurately depict the following characteristics: Map projection is an attempt to portray curved surface of the earth onto a flat surface with minimal distortion.
