摘  要：
农田电子地图是实施精准农业的重要基础数据,但长期以来它的绘制都需要专业的测绘设备、制图软件和技术人员。因此,利用GPS,GPRS和服务器GIS等技术,设计和实现了基于面向服务的体系架构(SOA)的农田测绘成图系统。该系统包括数据层、构件层、服务层和应用层。前3层对外提供了一系列数据和功能服务,实现自动成图、影像底图和测绘成果下载等功能;而应用层作为这些服务的请求者,包括基于智能手机的农田测绘设备和地图数据管理系统,前者能够实现待测区域影像下载,测绘信息上传和成图结果预览等;后者为用户提供了浏览、查询和下载测绘数据的快捷途径。通过在北京小汤山国家精准农业示范基地的试用,该系统能完成大田、设施和果园等多种农田地物的快速测绘,形成农田电子地图。

摘  要：
Electronic map of farmland is very important for carrying out precision agriculture.However,professional mapping equipments,mapping software and tenchnicists were needed during the cartography.Therefore the surveying and mapping system for farmland using GPS,GPRS and Server GIS was designed and implemented based on service-oriented architecture(SOA).The system consisted of four parts:data layer,component layer,service layer and application layer.The first three parts provided necessary web services of data and function,such as electronic map automatic generation,remote sensing image and mapping results download.The application layer,as the requester to these services,consisted of two parts,the surveying and mapping equipment for farmland based on smartphone and the management system of map data.The former could download high-resolution remote sensing image based on the coordinates of surveying region,upload the data of surveying recorded and display the preliminary mapping results in order to check and correct the results at the scene.The latter provided rapid way to browse,query and download the electronic map of farmland by the web client.The system was applied at the State Precision Agriculture Demonstration Base in Beijing.The results showed that the system was able to achieve fast cartography of farmland which includes fields,facilities and orchards.
