Entity model and its application for thematic analysis of construction land

Abstract

Abstract: The traditional construction land data organization and management mode based on GIS segmentation and layering is difficult to meet the needs of land life cycle data association application in the process of natural resources digital transformation. How to release the value of natural resources and spatial geographic data to meet the diversified and rapid data thematic analysis needs,in the process of natural resources digital transformation still has a large exploration space at this stage. Based on the analysis of the policies and regulations and the technical guidance documents of the Ministry of Natural Resources,this paper puts forward the idea of building the physical model of construction land,selects the pilot area to build the thematic analysis data environment of construction land,and explores the implementation path of one-click rapid thematic analysis around five typical thematic application scenarios,including batch but not supplied quantity accounting,construction land backtracking,idle land analysis,temporary land monitoring and supervision,and suspected illegal land identification.It provides exploration experience for the construction and application of physical data in the process of digital transformation of natural resources.

Key words: construction land, entity, solid model, thematic analysis
