you need the terragear toolchain , elevation data and shapefiles.
Shapefiles you can draw with Qgis or maybe obtain from OpenStreetMap.
And why can't random structures populate airports? I realize the last two questions are a bit off topic, probably.
I would not like random placed objects on airports.
There are 2 better options for auto-generation:
1.) use osm2city to generate buildings from OSM data
2.) I made a program that reads the building footprint from gateway scenery packages(.dsf files) and writes buildings.osm(OpenStreetMap XML) file to be used with osm2city:
https://github.com/mherweg/d-laser-fgto ... 2aptdat.pyThose buildings fit better to Project3000 objects.
test case: Unalakleet. - no village buildings mapped in OSM. So let's try this tool:
https://gitlab.com/vanosten/owbbOWBB stands for OpenStreetMap Would-Be Buildings. OWBB is a Python 3.x5+ based library to enhance OpenStreetMap (OSM) data with plausible buildings, where the density of the contributed map data for Building is not sufficient
The nicest result you'll get if you model the building yourself with sketchup, ac3d or blender.
here are some osm2city screenshots:
(roads.py is making roads, it is included in the osm2city package)
