detailed map of the secure areas that are off-limits to the general public,
but they are unlikely to place that information into a publicly-accessible
database. As you say, the public map will show (1) areas available to
everyone, (2) areas available only to passengers who have cleared security
checkpoints, and (3) areas accessible only to authorized personnel, shown
on the public map only as an amorphous block. Even for internal use,
different versions of the secure-areas map are likely to exist.</p><div class=""><br class=""></div></div></div></div></div></blockquote><span class=""><br class=""></span><span class=""><br class=""></span><span class=""><a href="http://sanmap.san.org/Html5Viewer/Index.html?viewer=sanmap" class="">http://sanmap.san.org/Html5Viewer/Index.html?viewer=sanmap</a></span></div><div><br class=""></div><div><br class=""></div><div>Zoom in on the terminals. the official airport map shows where the checkpoints are, what is considered secure, and other areas of the terminal. </div><div><br class=""></div><div>Becuase this is OSM, we also map the outside of the airport too. </div><div><br class=""></div><div>Having a bit more detailed maps, maybe using some industry terms - but not revealing anything that isn’t publicly viewable or knowable - isn’t a big deal. </div><span class=""><div class=""><br class=""></div><a href="https://en.wikipedia.org/wiki/San_Diego_International_Airport#/media/File:SAN_-_FAA_airport_diagram.gif" class="">https://en.wikipedia.org/wiki/San_Diego_International_Airport#/media/File:SAN_-_FAA_airport_diagram.gif</a></span><div class=""><br class=""></div><div class="">Mapping where hundreds of thousands of gallons of Jet fuel is stored at Narita (all those storage tanks!) seems like a “bigger risk” to me. <br class=""><div class=""><span class=""><br class=""></span></div></div><div class=""><span class=""><br class=""></span></div><div class=""><span class="">Javbw</span></div></body></html>
