- <p>This example demonstrates using the ArcGISCache layer for
- accessing ESRI's ArcGIS Server (AGS) Map Cache tiles through
- an AGS MapServer. 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>A few attempts have been made at this kind of layer before. See
- <a href="http://trac.osgeo.org/openlayers/ticket/1967">here</a> and
- <a href="http://trac.osgeo.org/openlayers/browser/sandbox/tschaub/arcgiscache/lib/OpenLayers/Layer/ArcGISCache.js">here</a>.
- A problem the users encounter is that the tiles seem to "jump around".
- This is due to the fact that the max extent for the cached layer actually
- changes at each zoom level due to the way these caches are constructed.
- We have attempted to use the resolutions, tile size, and tile origin
- from the cache meta data to make the appropriate changes to the max extent
- of the tile to compensate for this behavior.</p>
- You will need to know:
- <ul>
- <li>Max Extent: The max extent of the layer</li>
- <li>Resolutions: An array of resolutions, one for each zoom level</li>
- <li>Tile Origin: The location of the tile origin for the cache in the upper left.</li>
- <li>Tile Size: The size of each tile in the cache. Commonly 256 x 256</li>
- </ul>
- <p>It's important that you set the correct values in your layer, and these
- values will differ from layer to layer. You can find these values for your
- layer in a metadata page in ArcGIS Server.
- (ie. <a href="http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer">http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer</a>)</p>
- <ul>
- <li>Max Extent: Full Extent</li>
- <li>Resolutions: Tile Info -> Levels of Detail -> Resolution</li>
- <li>Tile Origin: Origin -> X,Y</li>
- <li>Tile Size: Tile Info -> Height,Width</li>
- </ul>
-
- <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_direct.html">prebuilt tiles in a file store
- (not 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>
