Development and application of field survey technology based GPS and GIS for land consolidation

Field survey in land consolidation is a complex and high-tech process. The deficiencies of the traditional methods resulted in difficulties of locating, measuring, recording, etc., therefore advanced technology is urgently required. For the scientific management aim of land consolidation, GPS and Mobile GIS were integrated and developed an advanced system, which supports field survey of land consolidation with the advantages of low cost,high efficiency, portable type, user friendly. The key achievement has been applied to the inspection of land development projects and spot check of the occupying and compensating equilibrium item successively in provinces of Qinghai, Beijing, Yunnan, Guangdong, Gansu, etc.. The practicing indicates the system completely reached the anticipative objective. Using such techniques can improve the quality and efficiency of field surveying, help us to solve many difficulties, simplify the complex field surveying and make passive research more active.
