Improvement of Positional Accuracy of Agricultural Cadastre Using Global Positioning System and Geographic Information Systems

Abstract

The importance arise from the cadaster is keeping the land ownership, is help to use the land by economic way and optimum use . The management of ownership depend on the accurate definition boundaries of ownership that depend on the system of cadaster (Torrens’ system) in the system the determine of boundaries depend on the large scale map as (1:5000). The boundaries are subject of removal by the effect of natural and human causes. In this case the boundaries must relocated accurately. In this study a method had been suggested to save the ownership boundaries coordinates in a digital layers, by observing few points by GPS as control point in the field. The observed control point had been used for georeferncing the digital map of the agricultural parcels in arc map software. Finally the coordinate of the boundaries of each agricultural parcel can be achieved for the digital map within 25 cm which as an acceptable accuracy in agricultural lands. By this method the removal of boundaries had been re-determine without going to the field.
