Why to use Plane Coordinates for Surveying?

Why to use Plane Coordinates for Surveying " In  geometry , a  coordinate system  is a system which uses one or more  numbers , or  coordinates , to uniquely determine the position of a  point  or other geometric element". ( Wikipedia ) Different Coordinate Systems Surveyors are using different co-ordinate system for different application.  Recent period, every body wants to match the geometry data with Google Earth.  Here, we want to discuss about 'why surveyors follow the plane coordinate system' Plane Coordinate System VS UTM  In order to make the coordinate system usable for engineering projects, the horizontal relationships should be defined as two dimensional on one (mapping) plane. To make the coordinate system usable and to simplify linear measurement, the coordinate system should be rectangular so that equal values measured from a datum axis form a parallel line with that axis. Parallel lines to each of the two axes fo...
