ArcGIS Server Map Cache Example (Direct Access)</h1>

<p id="shortdesc">
Demonstrates the basic initialization of the ArcGIS Cache layer using a prebuilt
configuration, and direct tile access from a file store.

<div id="docs">
<p>
This example demonstrates using the ArcGISCache layer for accessing ESRI's 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.</p>
<h2>
Notes on this Layer</h2>
<p>
It's 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. <a
href="http://serverx.esri.com/arcgiscache/dgaerials/Layers/conf.xml">
http://serverx.esri.com/arcgisca ... /conf.xml</a>)</p>
<p>
For fused map caches this is often
http:<i>ServerName</i>/arcgiscache/<i>MapServiceName</i>/Layers
<br>
For individual layer caches this is often
http:<i>ServerName</i>/arcgiscache/<i>LayerName</i>/Layers
</p>
<h2>
Other Examples
</h2>
<p>
This is one of three examples for this layer. You can also configure this layer
to use <a href="arcgiscache_ags.html">prebuilt tiles from a live server.</a> It
is also possible to let this <a href="arcgiscache_jsonp.html">layer 'auto-configure'
itself using the capabilities json object from the server itself when using a live
ArcGIS server.</a>

==============================代碼結(jié)束=============================
第四步：雙擊打開剛才保存的文件，如果部署正確，則將會(huì)顯示離線WGS84衛(wèi)星地圖的瀏覽結(jié)果，如下圖所示。
當(dāng)然，你也可以通過以下網(wǎng)址進(jìn)行訪問，效果也是一樣的。
http://localhost:8080/OpenLayers-2.13.1/examples/Example_ArcGIS%20Server.html
以上即是如何將天地圖基于OpenLayers在服務(wù)器端進(jìn)行部署的全部過程及示例源碼，你可以基于此平臺(tái)并根據(jù)自己的實(shí)際需求作進(jìn)一步開發(fā)了。
