For the UK at least, Multimap has overhead photos and Ordinance Survey 1:50,000 mapping for airfields that you know are there. Since the runways etc. are usually all marked accurately on the OS map. Straight measurement (plus a UK National Grid to Lat/Long conversion) should do it accurately enough for a 'first cut'. For example, here is the deactivated USAF base at RAF Alconbury http://www.multimap.com/map/browse.cgi?client=europe&; X=522500&Y=277500&scale=50000&width=700&height=400 &gride=&gridn=&coordsys=gb&db=&overviewmap= &scale=50000&multimap.x=251&multimap.y=271 Its worth checking the photo though: the OS missed a length of taxiway. Interestingly the main runway 'X' is placed in the centre, not at the thresholds. The taxiways have an 'X' at each end however.
