with the statistic requirements of each land user in every piece of map, the cadastral map is well made to be appropriate to the data in the cadastral dossier.
The cadastral map represents the position, the shape, the area, the number of the plot and the type of land of each plot according to every user, meeting the requirements in the State land management at village, district, province and central levels
When establishing the Cadastral map, to unanimously utilize the coordinate framework network, the State-elevation networks. At present, we are utilizing the coordinate system VN 2000. Ellipsoidal WGS-84, the plane coordinate system UTM. The axle longitude is specially determined by the General Department of Cadastre (the Ministry of Natural Resources and Environment now) for each province. The zero point of the altitude of the base altitude point at HonDau-Haiphong city
Utility of the Cadastral map :
