Key Technologies of a Large-Scale Urban Geological Information Management System Based on a Browser/Server Structure

Urban geological information management systems based on a B/S structures are an inevitable trend in the development of smart geology and big data. Such systems are important platforms for promoting the sharing of data and services among different city entities. It is necessary to overcome the limitations of C/S or partial B/S structures and establish an urban geological information management system based on a comprehensive B/S structure, which is currently rare. According to the above questions, this paper focuses on three types of technical tasks to construct an urban geological information management system based on a B/S structure. In terms of data management, we leave many functions to the server, and group data by type. In terms of data application and sharing, we quickly query and graphically display the data from massive data sets, and perform collaborative analyses of different professional data. In terms of 3D geological modelling and analysis, in order to efficiently provide large-scale 3D geological model analysis in the browser, we explore a new data structure and algorithm for optimization modelling to reduce the amount of model and the number of calculations. Using the above technical methods, we develop a geological information management system for a city in eastern China. The system realizes the “One Map” function for land and resources, creates a platform for the sharing of geological data and services among different entities, and provides technical support for the construction of “smart cities”.
