Abstract:In order to strictly implement the work deployment of the Ministry of Natural Resources on doing a good job in site selection and route selection for construction projects, combining with the work requirements of "efficiently complete one thing"by the Provincial Party Committee and Provincial Government, the Department of Natural Resources of Shandong Province is committed to providing solid, detailed and optimized support for resource elements, effectively improving the administrative efficiency of construction project approval, conducting key technical research on multi-source heterogeneous 3D information cross domain fusion, large-scale 3D data updates, spatiotemporal knowledge services and other issues. A decision support system for site selection of major projects in real 3D is developed, gathering and integrating provincial terrainlevel and citylevel real 3D data. It also coordinates constraint and control data such as urban development boundaries, permanent basic farmland, and ecological protection red lines, and builds a unified provincial geospatial base. This enables project land site selection to enter a new mode of threedimensionalization, intelligence, and panoramic view, and effectively promotes the improvement of quality and efficiency of land preexamination and site selection for construction projects in the whole province.
