| 摘 要： | 针对移动GIS应用商业开发组件难以进行自由定制与分发的问题,该文提出一种基于嵌入式Web服务器的Android移动端空间数据离线解决方法,该方法通过在Android设备中移植开源的NanoHTTPD服务器实现了地图瓦片服务和矢量要素服务,并通过编码读取bundle切片数据包和扩展Spatialite空间数据库的方式,解决了切片数据和矢量要素数据的存储,然后利用Webview控件内嵌HTML5页面加Leaflet地图库完成了前端功能实现,并进行了实际应用展示。该方案的实现可节省Android端移动GIS应用开发成本,具有推广意义。

| Abstract: | Aiming at the problem that the commercial application components of mobile GIS were difficult to be customized and distributed freely,this paper proposes an offline solution of Android mobile space data based on embedded Web server.The scheme realizes map tile service and vector elements service through the Android device porting open source Nano HTTPD server,and through encoding reading bundle slice data packets and extended spatial database solution slice data and vector data storage elements,and then use WebView controls embedded HTML5 pages and Leaflet map library to complete the front-end functions,and the actual application was showed.The implementation of this scheme can save the cost of Android mobile GIS application development,and has the promotion significance. |
