<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/arcgiscache/dgaerials/Layers/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>
