Abstract: In order to accelerate the construction of a unified monitoring system for provincial natural resources, we provide high-quality monitoring results and geographic information services by building a real 3D digital base that can be interconnected with real scenes. Under the framework of unified survey, with carrying out the monitoring of natural resources, we study the practical application of natural resources survey and monitoring based on 3D realistic geospatial scene. Taking natural resources monitoring provincial pilot of Changshu city for instance, the paper uses the technology of 3D realistic geospatial scene in order to provide the protection and management of natural resources in Changshu. The pilot results show that the multi-scale, time-series, and related 3D technology of real scene has strong expressiveness, accurate analysis results, and excellent monitoring effect, which can support the natural resource monitoring application scenarios with high quality.

Key words: 3D realistic geospatial scene, natural resource monitoring, multi-source data fusion, geospatial information, spatial data model
