A Methodology for linking local coordinates system in Juba Darius with Public Coordinates System in Syria

Search includes the geodetic study local network triangulation real estate in Slenfeh area, and propose a solution for the local network linking public real estate network in Syria based on a comparison of the 2D-Transformation results so as to choose the optimal conversion which avoids the occurrence of interactions between regions and schemes real estate and reduces distortions network after conversion (shift, rotation, scale). At first been touched to date geodesic network set up in Slenfeh region and the stages of execution, and the problems of engineering, and then to the transformation methods used in the link, and apply them to the network, and choose the best conversion, and set parameters optimal transformation, have been proposed solution depends on the network is divided into three segments so that Network least deformation resulting from the transformation in each sector. A computer program that has been prepared for the implementation of the transformation and linking local grid points by using the C # programming language. It has been verified the resultant transformation parameters by comparing linear measurements calculated from coordinates resulting from the transformation with linear measurements in the network observation records, and execution field measurements of some of the points and calculate its coordinates and compare it with the coordinates calculating fromtransformation.

Automation of cadastral plan by GIS

The programming interface presented in this research makes it possible to manipulate them easily and flexibly by all specialist users, as well as the possibility of managing, displaying, searching, amending and saving these plans through the approved programming interface which was applied to more than one real estate area. It is considered the foundation in the future comprehensive automation process of the Real Estate Department. In this research, the same real estate plotting approved by the General Real Estate Department was adopted ( real estate areas names and numbers) when manipulating them, using the ARC GIS 9 program.
