摘要
文中通过ESRI公司发布的ArcGIS for Android结合SQLite数据库的空间扩展Spatialite来构建客户端,服务端以PostgreSQL作为数据库,使用JavaEE的Servlets技术进行开发,构建了福州市实时路况系统,实现将所有空间数据离线储存在客户端,克服了传统的移动GIS需要从GIS服务器接收矢量数据或者切片数据耗费流量的缺陷,还减少GIS服务器架设。结果表明,通过ArcGIS for Android和Spatialite组合,不仅可在不影响用户体验的情况下,大量节省用户的流量,还降低服务器的架设难度和成本。
In this paper,combining the ESRI’ s ArcGIS for Android with Spatialite,the expansion of SQLite database,construct the client side. The server side using PostgreSQL as the database and JavaEE Servlets technology for development,construct Fuzhou real-time traffic system,implementing all the spatial database offline stored on the client side,overcoming the defect of costing a lot of stream caused by the traditional mobile GIS when it needs to get vector data or tile data from the GIS server,and reducing the installation of GIS server. The results show that by the combination of ArcGIS for Android and Spatialite,not only help users save a lot of traffic,but also reduce the cost of installation of GIS server.
