it better should, because people are mapping based on the semantics of the tags, which in many cases are asumed to be the meaning of the word, and often do not look up wiki definitions, nor are those definitions "perfect" (they are constantly being clarified, refined) and more seldomly redefined or deprecated. If the meaning of the word is different to the > > Famous cases: > A National Forest is not necessarily landuse=forest. > A National Park is likely never leisure=park. > these are not so good examples to make your point, as the terms are not "forest" and "park", but "national forest" and "national park". If you'd tag these with boundary=national_park or protection_title=National Forest, nobody will probably complain (if you live in areas with "National Forests" and "National Parks", you'd know that these are not landuses anyway).

Under this definition, you could at most map those airstrips as runways that are _on an airport_ (if these exist). Note that it says "airport", not "aerodrome". Cheers, Martin
