In order to, effectively, explore the presented hardware, we have to choose the suitable and require software. Its helps us to plan surveys for optimum satellite periods. The CAD module allows us to manipulate the processed data files so as to produce CAD drawings. The second module is used for string all our GPS observation. Other software components used in this study are AutoCAD drawing environment and Visual Basic.
AutoCAD program is adopted for design process so as to establish topographic and cadastral plans.
Every one, is familiar with engineering design procedures inside AutoCAD system, for this reason we incorporate it in our application. Their major purpose is to take advantage of the increase of technology. In addition the conventional measurement, user friendly methods, often have significant problems. Therefore, we proposed a new methodology for GPS surveying to overcome some difficulties of conventional approach. More efficiency can be achieved if we deal with the following steps.
