Studying the Distortion Impact of the Coordinates as a result of using the Coordinate Extension from Zone to Zone

Abstract

The transformation between zone to zone is successfully applied to the set of the coordinates of selecting project. When a combat area includes more than one grid zone, transformation may be required. In the UTM grid zones, there are overlap areas; however, transformation is not restricted to these overlap areas. Grid coordinates and azimuths can be transformed from any point in one zone into terms of an adjacent zone. The problem is solved by using different approved software’s like ERDAS Imaging 9.2 and Franson CoordTrans to get the same results for one set of coordinate’s extent from UTM-WGS84 –Zone 38N to UTM-WGS84 –Zone 39N in the south of Iraq. The coordinates of the project is measured on the site by considering the total length of the project (100 Km) lies at the zone 38N while actually only 26 km lays in such zone and nineteen control points as base line points had been distributed .....
