Yahoo Maps for ActionScript 3
Yahoo has released their Yahoo Maps API for AS3 which allows web developers to add mapping capabilities to Flash. Cool now we can use either Google Maps or Yahoo Maps in our Flash or Flex applications. Initiate the map simply by:
var yahooMap:YahooMap = new YahooMap("YOUR-APPID", stage.stageWidth, stage.stageHeight);
Ted Patrick has posted some of its features here.
