Abstract

Abstract: In order to realize the integrated management of natural resources and real estate such as mountain, water, forest, field, lake and grass, ministry of natural resources must consider the elements of natural ecology as a whole, which above and below the mountain, on the surface and underground, on land, in the sea, and upstream and downstream of a river basin land, to realize the integration and connection of various natural resources and real estate registration data in the whole national space. However, traditional 2D information technology has inevitable shortcomings in the expression of total factor information, the topological expression of multiple resources and the supervision and analysis of resources. To make up for the shortage of 2D GIS, new 3D GIS technology gradually formed, including data model that can express natural resources and real estate objects in full space, multi-scale, multi-source and heterogeneous 3D data fusion technology, and 3D spatial analysis and calculation technology, and realize the comprehensive management of natural resources and real estate information. On the basis of the new 3D GIS technology, the information management platform of natural resources and real estate is established to recognize the life community of mountains, rivers, forests, fields, lakes and grasses from a new perspective, improve the service capacity of natural resources and real estate management system, and realize the integrated management, use control and decision-making ability of natural resources and real estate information.

Key words: new 3D GIS, natural resources, real estate, multi-source data fusion, information management platform
