Based on openlayers to achieve military plotting
2.5
Application background 1. In fact, the GIS, the network will provide the military plotting functions, such as ArcGIS, hypergraph, MAPGIS; but most of them are non open source, and fees.2. Here would like to thank the hypergraph hypergraph open source plotting expansion symbol library, I use here is the hypergraph of the library and slightly extended the openlayers can be used. No openlayers source code. Key Technology The extended hypergraph plotting symbol library in SuperMap change openlayers. Then the lib\EXT\Extend.js in can directly use, see the file compression package.
