如何将天地图在基于OpenLayers的服务器端进行部署方法.doc

如何将天地图在基于OpenLayers的服务器端进行部署的方法一、准备工作1、 到OpenLayers的官方网站下载压缩包，如下图所示。2、到水经注软件官方网站下载天地图卫星地图下载器。二、下载示例数据这里以天地图卫星地图下载器为你说明如何下载天地图卫星地图。安装天地图卫星地图下载器以后，启动软件，如下图由于只是为了作演示说明如何在OpenLayers中使用离线卫星地图，这里我们只需要框选中国范围，即点击工具栏上的“框选下载区域”，然后在视图中绘制选择范围，如下图所示。在范围中双击鼠标左键，显示新建任务对话框，在该对话框中我们只选择3到7级进行下载即可，如下图所示。下载完成后，导出ArcGIS Server瓦片，如下图所示。点击“输出”按钮，开始导出。等待导出完毕，会在D盘Test目录看到“中国_ArcgisServerTiles”这个文件夹，如下图所示。然后将“中国_ArcgisServerTiles”文件夹重命名为“data”，如下图所示。三、服务器端地图引擎配置第一步：将下载的OpenLayers-2.13.1.zip解压到D盘Test目录。如下图所示。第二步：新建网站在IIS中新建网站，如下图所示。这里我们将网站命名为“TEST”，物理路径设置为“D:Test”，端口设置为“8080”，如下图所示。第三步：将以下代码复制并保存为html文件（如“Example_ArcGIS Server.html”），放到“D:TestOpenLayers-2.13.1examples”目录中。=代码开始= ArcGIS Server Map Cache Example (Direct Access) /* First 4 variables extracted from conf.xml file */ /* Tile layers & map MUST have same projection */ var proj = EPSG:4326; /* Layer can also accept serverResolutions array * to deal with situation in which layer resolution array & map resolution * array are out of sync*/ var mapResolutions = 1.40625, 0.703125, 0.3515625, 0.17578125, 0.087890625, 0.0439453125, 0.02197265625, 0.010986328125, 0.0054931640625, 0.00274658203125, 0.001373291015625, 0.0006866455078125, 0.00034332275390625, 0.000171661376953125, 0.0000858306884765625, 0.00004291534423828125, 0.000021457672119140625, 0.0000107288360595703125, 0.00000536441802978515625, 0.000002682209014892578125, 0.0000013411045074462890625, 0.00000067055225372314453125 ; /* For this example this next line is not really needed, 256x256 is default. * However, you would need to change this if your layer had different tile sizes */ var tileSize = new OpenLayers.Size(256, 256); /* Tile Origin is required unless it is the same as the implicit map origin * which can be affected by several variables including maxExtent for map or base layer */ var agsTileOrigin = new OpenLayers.LonLat(-180, 90); /* This can really be any valid bounds that the map would reasonably be within */ /* var mapExtent = new OpenLayers.Bounds(293449.454286,4307691.661132,314827.830376,4323381.484178); */ var mapExtent = new OpenLayers.Bounds(-180, -90, 180, 90); var aerialsUrl = http:/localhost:8080/data/_alllayers; var map; function init() map = new OpenLayers.Map(map, maxExtent: mapExtent, controls: new OpenLayers.Control.Navigation(), new OpenLayers.Control.LayerSwitcher(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.MousePosition() ); var baseLayer = new OpenLayers.Layer.ArcGISCache(Aerials, aerialsUrl, tileOrigin: agsTileOrigin, resolutions: mapResolutions, sphericalMercator: false, maxExtent: mapExtent, useArcGISServer: false, isBaseLayer: true, type: jpg, projection: proj ); map.addLayers(baseLayer); /map.zoomToExtent(new OpenLayers.Bounds(295892.34, 4308521.69, 312825.71, 4316988.37); map.setCenter(new OpenLayers.LonLat(103,31).transform(map.displayProjection, map.getProjectionObject(), 3); ArcGIS Server Map Cache Example (Direct Access) Demonstrates the basic initialization of the ArcGIS Cache layer using a prebuilt configuration, and direct tile access from a file store. This example demonstrates using the ArcGISCache layer for accessing ESRIs ArcGIS Server (AGS) Map Cache tiles directly via the folder structure and HTTP. Toggle the visibility of the AGS layer to demonstrate how the two maps are lined up correctly. Notes on this Layer Its important that you set the correct values in your layer, and these values will differ between tile sets. You can find these values for your layer in conf.xml at the root of your cache. (ie. /arcgiscache/dgaerials/Layers/conf.xml) For fused map caches this is often http:ServerName/arcgiscache/MapServiceName/Layers For individual layer caches this is often http:ServerName/arcgiscache/LayerName/Layers Other Examples This is one of three examples for this layer. You can also configure this layer to use prebuilt tiles from a live server. It is also possible to let this layer auto-configure itself using the capabilities json object from the server itself when using a live ArcGIS server. =代码结束=第四步：双击打开
