基于移动GIS的地块采集系统设计与实现

摘要

为解决传统的国土资源核查工作无法及时、准确、方便地核查企业的土地资源等信息,设计并研制基于移动GIS的地块采集系统.系统采用ArcServer搭建WMS地图服务,使用基于Android平台的ArcGIS RuntimeSDK for Android进行二次开发,通过Web Service实现采集数据的实时同步更新.分析了土地核查系统的架构体系、功能模块和数据库设计,实现了一种基于拓扑规则的地块采集方案,保证了采集的多边形面块符合拓扑规范,也保证了数据的正确性和精确性.同时还解决了多人在线同时采集同一面块的冲突问题,并通过GeoJSON技术实现移动端与服务端的空间数据实时交互.通过土地核查的应用实例结果表明,该系统具有较好的采集效果.%In order to solve the problem that the traditional land resources verification work can't timely, accurately and conveniently check the land resources of enterprises, the land block collection system based on mobile GIS is designed and developed.The system uses ArcGIS Server to build WMS map service, uses the ArcGIS Runtime SDK for Android based on Android platform to carry out the second development, achieves the real-time synchronization of data acquisition by Web Service.This paper analyses the verification of land block collection system architecture, function module and database design, and achieves a solution of land block collection based on topology rules, and ensures the polygons collected to comply with the standard topology, and ensures the validity and accuracy of the land block data.The land block collection system solves the problem of the conflict between multiple people online at the same time, and realizes the real-time interaction between the mobile end and the server end through GeoJSON technology.The application results of land verification show that the system has a good effect.
