基本上,我希望下面的示例http://openlayers.org/dev/examples/mapguide.html针对此WMS数据源“ http://gis.aarhus.dk/mapguide/mapagent/mapagent.fcgi?USERNAME=Anonymous&”进行操作;
到目前为止,我所做的只是更改网址。
var url = "http://gis.aarhus.dk/mapguide/mapagent/mapagent.fcgi?USERNAME=Anonymous&";
我找到了以下在线文档http://dev.openlayers.org/docs/files/OpenLayers/Layer/MapGuide-js.html,但我不知道从何处获取这些参数的正确值。
var metersPerUnit = 111319.4908; //value returned from mapguide
var inPerUnit = OpenLayers.INCHES_PER_UNIT.m * metersPerUnit;
OpenLayers.INCHES_PER_UNIT["dd"] = inPerUnit;
OpenLayers.INCHES_PER_UNIT["degrees"] = inPerUnit;
OpenLayers.DOTS_PER_INCH = 96;
var extent = new OpenLayers.Bounds(-87.764987, 43.691398, -87.695522, 43.797520);
var tempScales = [100000, 51794.74679, 26826.95795, 13894.95494, 7196.85673, 3727.59372, 1930.69773, 1000];
var params = {
mapdefinition: 'Library://Samples/Sheboygan/MapsTiled/Sheboygan.MapDefinition',
basemaplayergroupname: "Base Layer Group"
};
如何获得上述参数的正确值?
最佳答案
您应该能够从GetCapabilities请求中获取有关WMS的信息,您的情况应如下所示:
