GeoFeeder

GeoFeeder is a GeoRSS viewer in Adobe AIR.
It focuses on the map (in all flavors: Virtual Earth, Google Maps, Yahoo Maps, OpenStreetMap …) and on the data.

An advanced, html-capable tooltip window displays the feed-entries’ information. A list allows for simple sorting by title. It’s feed “database” is shared between all installations to aggregate as many interesting sources as possible.
