最好的学习资料ArcGIS api fo silverlight官网:http://help.arcgis.com/en/webapi/silverlight/samples/start.htm
一、GeoServer环境搭建及数据发布
参考:http://www.cnblogs.com/beniao/archive/2011/01/08/1930822.html等
二、创建ArcGIS API for SilverLight应用
参考:http://blog.csdn.net/zdw_wym/article/details/7620962
1、创建SilverLight应用程序
2、添加ArcGIS API for SilverLight相关引用
3、往MainPage.xaml中添加地图控件代码
四、读取GeoServer后台发布的图层
参考出处:http://blog.csdn.net/xinruogis/article/details/5567103
1、创建类文件,实现自定义wms
public class WMSMapServiceLayer : DynamicMapServiceLayer //继承接口,实现GetUrl方法
{
List<string> _layers = new List<string>();
public WMSMapServiceLayer(Envelope extent, int KWID, string url, string[] layers)
{
this.FullExtent = extent; //地图范围
this.SpatialReference = new ESRI.ArcGIS.Client.Geometry.SpatialReference(KWID); //空间参考
this.Url = url; //wms地址
this.Version = "1.1.1"; //wms版本
this.Layers = layers; //请求的图层
// _layers.Add("topp:states");
}
public string Url { get; set; }
public string Version { get; set; }
//public Envelope Extent { get; set; }
public string[] Layers
{
get { return _layers.ToArray(); }
set { _layers = new List<string>(value); OnLayerChanged(); }
}
//public override void Initialize()
//{
// // this.FullExtent = Extent; //设置范围(不设置就无法实现)
// //this.SpatialReference = new SpatialReference(KWID);
// base.Initialize();
//}
//重写获取数据接口的方法
public override void GetUrl(ESRI.ArcGIS.Client.Geometry.Envelope extent, int width, int height, DynamicMapServiceLayer.OnUrlComplete onComplete)
{
int extentWKID = extent.SpatialReference.WKID;
StringBuilder mapURL = new StringBuilder();
mapURL.Append(Url);
mapURL.Append("?service=WMS");
mapURL.Append("&request=GetMap");
mapURL.AppendFormat("&width={0}", width);
mapURL.AppendFormat("&height={0}", height);
mapURL.AppendFormat("&format={0}", "image/png");
mapURL.AppendFormat("&layers={0}", String.Join(",", Layers));
mapURL.Append("&styles=");
mapURL.AppendFormat("&bgcolor={0}", "0xFFFFFF");
mapURL.AppendFormat("&transparent={0}", "true");
mapURL.AppendFormat("&version={0}", Version);
switch (Version)
{
case ("1.1.1"): mapURL.AppendFormat("&SRS=EPSG:{0}", extentWKID);
mapURL.AppendFormat(CultureInfo.InvariantCulture, "&bbox={0},{1},{2},{3}",
extent.XMin, extent.YMin, extent.XMax, extent.YMax); break;
}
//把那些字符串拼接起来,跟openlayer一样的
onComplete(mapURL.ToString(), width, height, new ESRI.ArcGIS.Client.Geometry.Envelope()
{
XMin = extent.XMin,
YMin = extent.YMin,
XMax = extent.XMax,
YMax = extent.YMax
});
}
}
2、调用代码(MainPage.xaml.cs)
int KWID = 4326;
Envelope extent = new Envelope(105.487843, 31.706997, 111.239656, 39.58577);
extent.SpatialReference = new SpatialReference(KWID);
string Url = "http://localhost:8080/geoserver/wms";
string[] layers = new string[] { "shanxi:piovrnce_region", "shanxi:city_region", "shanxi:county_region", "shanxi:capital_point", "shanxi:city_point", "shanxi:county_point" };
WMSMapServiceLayer wms = new WMSMapServiceLayer(extent, KWID, Url,layers);
this.myMap.Layers.Add(wms);
