The Design And Implementation Of Geographic Information Service And Management System

In recent years,geographic information system(GIS)has been developing rapidly,while new theories and technologies such as big data and "Internet+traffic" are rising rapidly,which profoundly affects the construction of geographic information resource system.The development and construction of geographic information resources are in an important transition period from scattered to intensive,from isolated and closed to shared and open.This paper aims to design and implement a set of geographic information service management system through the analysis of the current situation of geographic information data usage in the transportation industry,combined with the national requirements for geographic information resource sharing management and the actual usage scenarios of users,and solve the problem of cross-department geographic information Data sharing and maintenance,and life cycle management of the calling process of geographic information service interfaces.The main work of this paper includes:1.According to the current situation of the transportation industry and the existing geographic information resource information,from the perspective of resource use,maintenance and management personnel,the overall demand is analyzed,and the system is divided:basic operation module,basic query module,data management module and Service management module.2.According to the results of the system module division,the functional architecture of the system is designed,and five functional modules are determined;according to the analysis of functional requirements,a six-layer technical architecture model is determined;the relationship diagram of geographic information entities is obtained and the database storage is designed.More fine-grained design of each module.3.Based on SpringBoot framework and using PostgreSQL database and PostGIS spatial expansion component to complete the back-end part of the work.The life cycle management of geographic information service calls is completed by using Kong gateway,and the monitoring of geographic information service calls is completed by using Logstash and Elasticsearch.The front-end uses Vue.js framework combined with WebGIS to realize the map interaction function on the web end.For the layers involved in the basic operation module,GeoServer combined with PostgreSQL is used to render and provide.4.Carry out detailed functional and non-functional tests on the system to ensure that the system can meet the daily needs of the enterprise.5.Combined with the current situation of the system and the existing geographic information resources,a summary and prospect of the future optimization and improvement direction are made.The implementation of the geographic information service and management system facilitates the sharing and maintenance of geographic information between departments,as well as the management of geographic interfaces,and is conducive to enhancing the efficiency of practitioners.
