Abstract:Accompanying with the development and maturity of 3S technology, it has been used in a wide scope. In this paper, the remote sensing satellite imagery data are rapidly acquired by using RS technology, the dynamic monitoring data is acquired by using GPS technology, the provincial renovation project database has been established by using the visualization technology of GIS and the powerful spatial analysis function. Based on the provincial land and resources system, following technical requirements for implementing "one platform, two markets" , making full use of existing networks, hardware and software infrastructure, the whole process of online operation and full regulatory mechanism in provincial, municipal and county land resources protection and management has been built, and the unified dynamic monitoring network of cultivated land protection has been constructed.
