I’ve created vector art silhouettes of the terminals and concourses of airports I’ve visited.
In each full-size image (SVG at default scale, or PNG), one pixel equals one meter. (The thumbnails each show a square 1.33 km or 0.83 miles on each side.) True north is always up.
I’ve also drawn silhouettes of some other buildings.
I draw these silhouettes as SVG vector images with Inkscape, an open source vector graphics editor.
My primary references are Google Earth and Bing Maps satellite imagery, supplemented by other satellite imagery, terminal maps on airport websites, airport photos and videos, and my own memory of each airport.
