Geo - transform

Abstract

This project aims to build geodetic transformation software using visual basic 6 programming language. This tool should be able to transform geographic coordinates (a,q,h) to geocentric coordinates (x,y,z) , and from geographic coordinates (a,q ) to projected coordinates (easting, northing) and in the opposite direction using casini, transverse Mercator ™ and universal transverse Mercator ( UTM). So that for surveying point there would be no need to use expensive software , and the time will not be spent to draw the point in the software format like GIS and CAD software. There are many software available to apply these calculation, such as arcview, arc GIS , autodesk land desktop. ER mapper, ERDAS , … etc , but these software are expensive for single user. The project coordinates system used are: Palestine-1923 belt, Palestine-1923 old grid , and the Israel transverse Mercator, in addition a separate datum transformation tool is to be built, to calculate the datum transformation parameters using different transformation method, similarity 7 – parameters, similarity 6-parameters, similarity 3-parameters, moldensky transformation and helmert transformations. The final product will be software can be setup at any computer to calculate different types of coordinates for single or multipoint calculations.
