Once you have generated your tiles from a map services, you can move these tiles to
Amazon S3. I used the
S3Fox Firefox extension to move the files from my local system to S3. In addition, make sure to copy the JSON map service metadata to a file named "MapServer" (without quotes of course :-). You can access these tiles using the Flex API for ArcGIS server as follows:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns:esri="http://www.esri.com/2008/ags"
xmlns:s3="com.esri.s3.*"
layout="absolute"
>
<esri:Map>
<s3:S3ArcGISTiledMapServiceLayer
url="http://s3.amazonaws.com/your_map_service/MapServer"/>
</esri:Map>
</mx:Application>
And here is the implements of
S3ArcGISTiledMapServiceLayer class:
package com.esri.s3
{
import com.esri.ags.layers.ArcGISTiledMapServiceLayer;
import flash.net.URLRequest;
public class S3ArcGISTiledMapServiceLayer extends ArcGISTiledMapServiceLayer
{
private var m_baseURL : String;
public function S3ArcGISTiledMapServiceLayer(url:String=null)
{
super(url);
}
override public function set url(value:String):void
{
super.url = value;
if( value )
{
var index : int = value.lastIndexOf( "/" );
m_baseURL = value.substr( 0, index );
}
else
{
m_baseURL = "";
}
}
override protected function getTileURL(
level:Number,
row:Number,
col:Number
):URLRequest
{
return new URLRequest( m_baseURL + "/l" + level + "r" + row + "c" + col + ".jpg" );
}
}
}
Note that I simplified the storage retrieval in the
getTileURL function. ArcGIS places the tiles on the file system as a set of sub-directories of the form level/row/column.jpg. I decided (out of laziness :-) to keep it flat and have a set of files in the form lXrXcX.jpg.
