Design and Implementation of Geological Environment Survey Big Data Platform for Danjiangkou Reservoir Water Source Area Based on WebGIS

Danjiangkou reservoir water source area is the source of the water source area of south-to-north water diversion. In order to confirm the specific conditions of the local geological environment, geological environment surveys occupy a very important position. During the survey, a large amount of geological environment data was generated. These data are extremely scattered and cannot be used in a comprehensive manner. For more efficiently using the geological environment survey data and realizing the function of polyphyletic, heterogeneous data management and real-time dynamic update, the paper explained how to use the SQL Server database, rely on the MapGIS geographic information system platform, and carry out secondary development based on the double services of the MapGIS IGServer, and establish a Geological Environment Survey Big Data Integration System based on WebGIS. The polyphyletic, heterogeneous spatial data and attribute data are uniformly processed, stored, searched, managed and analyzed. Data support will be provided for in-depth geological research, analysis and land planning for the Danjiangkou Reservoir water source area on this system platform.
