基于SOA的实时动态专题地图服务生成方法

Real-time Dynamic Thematic Map Service Generation Method Based on SOA

针对用户不能在线实时获得个性化专题地图的问题,以ArcGIS的SOA架构为技术支撑,提出一种实时动态专题地图服务生成方法。采用契约优先的Document样式封装服务,利用支持OGC标准的Web服务发布地图数据,使用扩展的二维数据表的叠加操作策略,实现地图数据与第三方渲染数据的融合,以及渲染服务与地图数据发布服务的在线组合。以江苏省农林渔牧总产值为例在线制作系列专题地图,验证了该方法的有效性。

To solve the problem that the user can not obtain personalized real-time dynamic thematic map online,this paper proposes a generation method of Real-time Dynamic Thematic Map Service（RDTS）,which is based on ArcGIS server architecture.It uses the contract-first document style packaging service,distributes the map data by using the Web services which support the OGC standards,and realizes the map data and thirty-party rending data fusion by using extended two-dimensional data table overlay operations and the online combination of rending service and map data distribution service.The series thematic maps of the Jiangsu province total output values of agriculture,forestry,animal husbandry and fisheries are generated by RDTS.The effectiveness of generation method is verified.
