摘要
在B/S体系结构下,实现基于地图切片和Arc GIS Server地图服务的专题地图动态生成算法。分析了地图切片的组织特点及其像素与坐标的转换方法,运用标准的REST访问接口和GDI+技术,设计并实现了多尺度、多源数据的裁剪、拼接以及在特定位置渲染地图要素的算法。并以山东省测量标志动态监管信息系统为例,证明了该方法的可行性。
In the B/S mode,we designed an algorithm,which could generate dynamic thematic map based on map tiles and map services that published in ArcGIS Server platform.We analyzed the characteristics of map tiles and the conversion between the pixel location and the coordinate,utilized standard REST interface and GDI+ technology,designed the method that could cut and splice map data of multi-scale,multi-source and renders map elements in specific position of map.Finally,taking the dynamic supervision and management information system in Shandong Province for example,we demonstrated the feasibility of the method.
