Check out Andrew Trice's post on AWX usage. Pretty cool !

We use Flex logging capabilities to report debug, info and error information: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:framework="com.esri.aws.osgi.framework.*" layout="absolute" > <mx:TraceTarget/> <framework:Framework username="foo" password="bar" authenticationError="trace(event.getError())"/> </mx:Application>

If you are using Flex Builder , make sure that you set the output folder of the project to a web application folder. Remember, your api key is tied to a URL. To get to this setting, use File -> Properties -> Flex Build Path.

You can subclass BaseMapLayer to create a WMS basemap layer: package com.esri.aws.awx.map.layers { import com.esri.aws.awx.geom.Extent; import flash.geom.Point; import flash.utils.getTimer; public class WMSGroupLayer extends BaseMapLayer { public var service : String = "WMS"; public var version : String = "1.1.1"; public var request : String = "GetMap"; public var format : String = "image/png"; public var wmsLayers : String; public var serviceName : String; public var wmtVersion : String; public var styles : String; public var srs : String; public var dataSource:String; public var proxyURL : String; public function WMSGroupLayer() { super(); mapOversizeBuffer = 0; } override protected function getMap():void { m_lastMap = buildGeoLoader(); var scalarPt:Point = getScalar(); var width:Number = Math.floor(map.rotatedWidth * scalarPt.x); var height:Number = Math.floor(map.rotatedHeight * scalar...

Will be in Chicago at Adobe MAX 2007 , and presenting on: Monday, October 1 4:30 pm - 5:30 pm Tuesday, October 2 9:15 am - 10:15 am Hope to see you there.

You can take advantage of AWS data sources, in this case Precipitation.US , to view dynamic data. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:framework="com.esri.aws.osgi.framework.*" xmlns:map="com.esri.aws.awx.map.*" xmlns:layers="com.esri.aws.awx.map.layers.*" xmlns:services="com.esri.aws.services.*" layout="absolute" > <framework:Framework apiKey="19640523"> <services:MapImageActivator/> </framework:Framework> <map:Map centerLat="35" centerLon="-93" scale="20000000"> <map:basemaps> <layers:MapImageGroupLayer dataSource="ArcWeb:MX.Precipitation.US"> <layers:layerVisibilities> <layers:LayerVisibility name="U.S. States" visible="false"/> </layers:layerVisibilities> </layers:MapImageGroupLayer>...

As of today, the number of AWX2 beta users have reached a cool 883 !

Mapperz posted comments about AWX2 . Thanks.

You can use an ArcIMS datasource as a basemap, as follows: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:framework="com.esri.aws.osgi.framework.*" xmlns:map="com.esri.aws.awx.map.*" xmlns:layers="com.esri.aws.awx.map.layers.*" layout="absolute" > <framework:Framework apiKey="19640523"/> <map:Map> <map:basemaps> <layers:ArcIMSGroupLayer id="world" serviceHost="http://www.geographynetwork.com" serviceName="ESRI_World" /> </map:basemaps> </map:Map> </mx:Application> Don't forget to place a crossdomain.xml file at the base of your ArcIMS host. Check out the Geography Network cross domain file as a sample.

This code is based on the great work from Eli . You can download all the source code from here . So... in mxml it will look like this: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:map="com.esri.aws.awx.map.*" xmlns:framework="com.esri.aws.osgi.framework.*" xmlns:layers="com.esri.aws.awx.map.layers.*" xmlns:style="com.esri.aws.awx.map.layers.overlays.style.*" xmlns:overlays="com.esri.aws.awx.map.layers.overlays.*" xmlns:geom="flash.geom.*" > <framework:Framework/> <map:Map> <map:basemaps> <layers:PolylineLayer> <layers:style> <style:StrokeStyle> <style:stroke> <mx:Stroke color="0xFF0000" alpha="0.5" weight="5" caps="round"/> </style:stroke> <style:pattern...

Following the previous post, here is an example on how you will be able to use in the upcoming beta3 the polyline mouse handler to create a distance measuring tool. & lt ;? xml version="1.0" encoding=" utf -8"?> & lt ; mx :Application xmlns : mx ="http://www.adobe.com/2006/mxml" xmlns : utils ="com.esri.aws.awx.utils.*" xmlns :framework="com.esri.aws.osgi.framework.*" xmlns :map="com.esri.aws.awx.map.*" layout="absolute" > & lt ; mx :Script> & lt ;![ CDATA [ import com.esri.aws.awx.utils.Utils; import com.esri.aws.awx.map.layers.overlays.Polyline; import com.esri.aws.awx.events.OverlayEvent; import com.esri.aws.awx.map.handlers.PolylineMouseHandler; import com.esri.aws.awx.map.handlers.IMouseHandler; private var m_ mouseHandler : IMouseHandler ; private function doMeasure () : void { m_ mouseHandler = map. mouseHandler ; var mouseHandler : Polyl...

So when I asked my friend Kerry (who BTW is the king when it comes to map projections) how to calculate the distance between two lat/ lon points ? he pointed me to this link . He followed by saying "This is a good start, but what I have implemented in Java, takes care of all the 'weird' conditions!". This is why he is the king :-). So you can find the AS3 implementation here . And here is a simple MXML calculator. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import com.esri.aws.awx.utils.Utils; private function onClick() : void { var lat1n : Number = Utils.parseDeg(lat1.text); var lon1n : Number = Utils.parseDeg(lon1.text); var lat2n : Number = Utils.parseDeg(lat2.text); var lon2n : Number = Utils.parseDeg(lon2.text); var dist : Number = Util...

Following the last post, AWX can connect directly to a resource such as ArcIMS or even ArcGIS to get maps. The best way that I found out to see what crossdomain.xml the player is requesting, is to run the application in Firefox and watch the HTTP traffic using LiveHTTPHeaders.

Make sure that you have a crossdomain.xml file at the base of you web server that is hosting ArcIMS, ArcGIS or any host that you are trying to access data from that is not the host from which the swf was downloaded from. In such a way, that if you type http://your-host-name-info/crossdomain.xml in a web browser, you should get: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"> <cross-domain-policy> <allow-access-from domain="*" secure="false"/> </cross-domain-policy> If you cannot create that file on that host, then use/create a proxy with a crossdomain file.

In the current beta-2 version of AWX, you can create geographical circles using the Circle and CircleShape classes. In the beta-3 version, you will be able to do: <map:Map> <map:basemaps> <layers:PolygonLayer> <overlays:Circle centerLat="0" centerLon="0" radius="500000" units="meters"/> <overlays:Circle centerLat="45" centerLon="-80" radius="500" units="kilometers"/> <overlays:Circle centerLat="60" centerLon="80" radius="500" units="miles"/> </layers:PolygonLayer> </map:basemaps> </map:Map>
