Abstract

In the process of promoting the national territorial spatial planning system in all provinces, cities and counties, the geospatial database of "One Map" has realized the information sharing and collaborative work of multiple departments. Based on this, this paper intended to provide a set of standardized mapping models for industrial heritage storage, and through the establishment of the database to protect and reuse the status quo of industrial heritage research. This paper took the third-line construction industrial heritage of Mianyang "Two-Bomb City" as the research object, developed the relevant drawing standards of third-line industrial heritage database, and studied the database construction process. GIS technology is used to establish a geospatial database of the third-line industrial heritage in cooperation with the "One Map" system, in order to provide reference for the storage of the third-line industrial heritage in various places, and to protect and reuse the third-line industrial heritage from the perspectives of spatial factors, planning coordination and dynamic assessment.
