Design and application of GIS-based urban geological information management system
Geological spatial information data in geological surveys possesses characteristics such as large quantity,diverse types,and complex structures.Traditional geological survey methods are no longer sufficient to meet the needs of today's engineering projects.This paper,supported by GIS technology,designs a geological survey data service system.The system is aimed at field geological survey personnel and project management personnel.It can realize professional functions such as storage,management,updating,synthesis,querying,analysis and evaluation,and visual expression of massive geological survey data,groundwater monitoring data,as well as related vector and elevation data.In practical engineering cases,the system has received positive feedback,providing assistance for geological workers and aiding decision-makers in judgment.It has high practical value.
