that provides a great level of geo-location search. in the authors' own words:
"Map2Explore.com is a merge between Google Maps and Google Earth withGeonames.org, Wikipedia and Microsoft Flight Simulator databases. TheGeoNames database contains over 8,000,000 geographical namescorresponding to over 6,500,000 unique features and Wikipedia.orgcontains up to 230,000 articles. With a special marker from GoogleMaps (Magic Menu) you can drag it at a location in order to searchinformation about the region like the nearest Wikipedia articles,airports, photos and local geographical features that you can exporttowards Google Earth."
this site really makes world browsing for place names quite easy, and the linkage between that ability and ICAO designators ( which pop up in their own scrollbox ) makes airfield location a breeze. and that is just part of what it offers.
