Apple’s DashCode has a GeoRSS Widget template
I was pleasantly amazed to find out that Apple’s DashCode includes a Project Template for building a “Maps Widget” that handles GeoRSS feeds and KML documents.
If you’re not familiar with them, Apple Mac OS X provides Dashboard Widgets - which are small HTML and Javascript enabled windows that can quickly display information such as sports scores, travel information, stocks, and thousands of other applications. Apple’s recently released update to their operating system, Mac OS 10.5, aka Leopard, includes the final version of DashCode. DashCode is a development environment for building these widgets.
Building a Map Widget is simple: select the project, add a GeoRSS or KML URL, get a GoogleMaps API Key (confusing because Google requests a URL, which isn’t actually used by the widget), Save it and you’re done - near instant Map Widget.
