ArcGIS API for Silverlight 加载BingMap,GoogleMap,WorldImageryMap,OpenStreetMap,BaiduMap方法

概述1.首先Silverlight前台加载esri:Map,示例代码如下： //添加引用xmlns:esri="http://schemas.esri.com/arcgis/client/2009"<pre name="code" class="html"> //添加esri:Map<esri:Map x:Name="TestMap" IsLogoVisible="False" Minimum

1.首先Silverlight前台加载esri:Map,示例代码如下：

//添加引用xmlns:esri="http://schemas.esri.com/arcgis/clIEnt/2009"<pre name="code" >

//添加esri:Map<esri:Map x:name="TestMap"  IslogoVisible="False"  MinimumResolution="0.01"  MouseMove="Subway_MouseMove"></span>            <esri:Map.Layers>                <esri:ArcGISDynamicMapServiceLayer ID="···" displayname="···" Initialized="···" Url="····" ></esri:ArcGISDynamicMapServiceLayer>                <esri:Graphicslayer ID="MyGraphicslayer"  Opacity="1"/>            </esri:Map.Layers>        </esri:Map>

2.后台添加地图

Map MyMap = this.LayoutRoot.Findname("TestMap") as Map;

A.BingMap

ESRI.ArcGIS.ClIEnt.Bing.TileLayer bingLayer = new TileLayer();bingLayer.ID = "BingMapLayer";bingLayer.displayname = "BingMap";bingLayer.LayerStyle = TileLayer.LayerType.AerialWithLabels;bingLayer.Visible = true;bingLayer.ServerType = ServerType.Production;bingLayer.Token = "AjXYD5KFgnm650vi1Q9VKNWFBORxoux7Y_UFrmuwqs0RvXSkVyfaNueRlPkLctKN";MyMap.Layers.Insert(0,bingLayer);

B.WordImagerMap

ArcGISTiledMapServiceLayer worldImageryLayer = new ArcGISTiledMapServiceLayer();worldImageryLayer.ID = "WorldImageryLayer";worldImageryLayer.displayname = "WorldImageryLayer";worldImageryLayer.Visible = true;worldImageryLayer.Url = "http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer";worldImageryLayer.Visible = false;MyMap.Layers.Insert(0,worldImageryLayer);

C.OpenStreetMap

OpenStreetMapLayer osLayer = new OpenStreetMapLayer();osLayer.ID = "OpenStreetLayer";osLayer.displayname = "OpenStreetLayer";osLayer.Style = OpenStreetMapLayer.MapStyle.Mapnik;osLayer.Visible = true;osLayer.Opacity = 1;MyMap.Layers.Insert(0,osLayer);

D.GoogleMap

首先添加一个类，命名为GoogletopographicLayer，类的代码如下：

using System;using System.Net;using System.windows;using System.windows.Controls;using System.windows.documents;using System.windows.Ink;using System.windows.input;using System.windows.Media;using System.windows.Media.Animation;using System.windows.Shapes;using ESRI.ArcGIS.ClIEnt;using ESRI.ArcGIS.ClIEnt.Geometry;namespace GoogleMap{    public class GoogletopographicLayer: TiledMapServiceLayer      {        private const double cornerCoordinate = 20037508.3427892;        private string _baseURL = "m@161000000"; //Google街道图        public overrIDe voID Initialize()        {            ESRI.ArcGIS.ClIEnt.Projection.WebMercator mercator = new ESRI.ArcGIS.ClIEnt.Projection.WebMercator();            this.FullExtent = new ESRI.ArcGIS.ClIEnt.Geometry.Envelope(-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892)            {                SpatialReference = new SpatialReference(102100)            };            //图层的空间坐标系              this.SpatialReference = new SpatialReference(102100);            // 建立切片信息，每个切片大小256*256px，共16级.              this.TileInfo = new TileInfo()            {                Height = 256,WIDth = 256,Origin = new MapPoint(-cornerCoordinate,cornerCoordinate) { SpatialReference = new ESRI.ArcGIS.ClIEnt.Geometry.SpatialReference(102100) },Lods = new Lod[16]            };            //为每级建立方案，每一级是前一级别的一半.              double resolution = cornerCoordinate * 2 / 256;            for (int i = 0; i < TileInfo.Lods.Length; i++)            {                TileInfo.Lods[i] = new Lod() { Resolution = resolution };                resolution /= 2;            }            // 调用初始化函数              base.Initialize();        }        public overrIDe string GetTileUrl(int level,int row,int col)        {            string url = "http://mt" + (col % 4) + ".Google.cn/vt/lyrs=" + _baseURL + "&v=w2.114&hl=zh-CN&gl=cn&" + "x=" + col + "&" + "y=" + row + "&" + "z=" + level + "&s=galil";            if (_baseURL == "s@92")            {                url = "http://mt" + (col % 4) + ".Google.cn/vt/lyrs=" + _baseURL + "&v=w2.114&hl=zh-CN&gl=cn&" + "x=" + col + "&" + "y=" + row + "&" + "z=" + level + "&s=galil"; //加载Google遥感图              }            if (_baseURL == "t@128")            {                url = "http://mt" + (col % 4) + ".Google.cn/vt/lyrs=" + _baseURL + ",r@169000000&v=w2.114&hl=zh-CN&gl=cn&" + "x=" + col + "&" + "y=" + row + "&" + "z=" + level + "&s=galil";//加载Google地形图              }            if (_baseURL == "m@161000000")            {                url = "http://mt" + (col % 4) + ".Google.cn/vt/lyrs=" + _baseURL + "&v=w2.114&hl=zh-CN&gl=cn&" + "x=" + col + "&" + "y=" + row + "&" + "z=" + level + "&s=galil"; //加载Google街道图              }            return string.Format(url);            //调用加载初始的Google街道地图              //string baseUrl = "http://mt2.Google.cn/vt/v=w2.116&hl=zh-CN&gl=cn&x={0}&y={1}&z={2}&s=G";              //return string.Format(baseUrl,col,row,level);          }      }}

        /// <summary>        /// Initialization BaIDuMap        /// </summary>        public voID InitGoogleMap()        {            GoogletopographicLayer GoogleMaplayer = new GoogletopographicLayer();            GoogleMaplayer.ID = "GoogleMapLayer";            GoogleMaplayer.displayname = "GoogleMap";            GoogleMaplayer.Visible = ture;            MyMap.Layers.Insert(0,GoogleMaplayer);        }

E.BaIDuMap

首先添加一个类，命名为BaIDutopographicLayer，类的代码如下:

using System;using System.Net;using System.windows;using System.windows.Controls;using System.windows.documents;using System.windows.Ink;using System.windows.input;using System.windows.Media;using System.windows.Media.Animation;using System.windows.Shapes;using ESRI.ArcGIS.ClIEnt;using ESRI.ArcGIS.ClIEnt.Geometry;namespace BaIDuMap{    public class BaIDuMapLayer : TiledMapServiceLayer      {        private const double cornerCoordinate = 20037508.3427892;        private string _baseURL = "POI"; //BaIDu地形图          public overrIDe voID Initialize()        {            ESRI.ArcGIS.ClIEnt.Projection.WebMercator mercator = new ESRI.ArcGIS.ClIEnt.Projection.WebMercator();            this.FullExtent = new ESRI.ArcGIS.ClIEnt.Geometry.Envelope(5916776.8,1877209.3,19242502.6,7620381.8)            {                SpatialReference = new SpatialReference(102100)            };            //图层的空间坐标系              this.SpatialReference = new SpatialReference(102100);            // 建立切片信息，每个切片大小256*256px，共16级.              this.TileInfo = new TileInfo()            {                Height = 256,int col)        {            int zoom = level - 1;            int offsetX =Convert.ToInt16(Math.Pow(2,zoom));            int offsetY = offsetX - 1;            int numX = col - offsetX;            int numY = (-row) + offsetX;            zoom = level + 1;            int num = (col + row) % 8 + 1;            string url = "";            if (_baseURL == "Vector")            {                url = "http://q" + num + ".baIDu.com/it/u=x=" + numX + ";y=" + numY + ";z=" + zoom + ";v=013;type=web&fm=44"; //加载BaIDu遥感图              }            if (_baseURL == "Image")            {                url = "http://q" + num + ".baIDu.com/it/u=x=" + numX + ";y=" + numY + ";z=" + zoom + ";v=009;type=sate&fm=46";//加载BaIDu地形图              }            if (_baseURL == "POI")            {                url = "http://online" + num + ".map.bdimg.com/tile/?qt=tile&x=" + numX + "&y=" + numY + "&z=" + zoom + "&styles=pl&udt=20140819";  //加载BaIDu街道图              }            return string.Format(url);        }      }}

/// <summary>        /// Initialization BaIDuMap        /// </summary>        public voID InitBaIDuMap()        {            BaIDuMapLayer BaIDulayer = new BaIDuMapLayer();            BaIDulayer.ID = "BaIDuMapLayer";            BaIDulayer.displayname = "BaIDu";            BaIDulayer.Visible = true;            MyMap.Layers.Insert(0,BaIDulayer);        }
