Autogen Scenery
Started in	11/2013
Description	Improved autogen support for FlightGear using OSM data
Contributor(s)	radi, vanosten, Soitanen, portreekid

Note A worldbuild of OSM2City output is automatically downloaded as you fly in FlightGear 2020.3.7+. To download OSM2City output separately for some regions and countries see Areas populated with OSM2City scenery.

Note If you are a scenery developer and want to use osm2city to generate scenery, then you need to download both the development repository and the texture data from GitLab.

Note Please use the osm2city.py development topic on the forum

for discussion and support.

osm2city is a set of procedural programs, which create plausible FlightGear scenery objects (buildings, roads, power lines, piers, platforms etc.) based on OpenStreetMap (OSM) data. FlightGear 2020.3.7 added the 1st worldbuild of OSM2City.py output to scenery automatically downloaded through TerraSync.

Documentation regarding installation and usage can be found on osm2citiy's Read The Docs site.
Written in Python 3.5, developed on Linux. It should also run on Windows and Mac OSX, however most testing is done on Linux.

Programs and feature areas

osm2city contains the following programs to generate scenery objects based on OSM data:

buildings.py: Generates buildings honoring OSM height and level tags as well as reads relations ('buildings with holes'). Includes lightmaps, complex sloped roofs (using Olivier Teboul's implementation of the straight skeleton algorithm), obstruction lights on tall buildings. Texturing of roofs and facades based on a texture manager, which find matching texture for given building (number of levels, modern/old building, etc).

roads.py: Generates different types of roads and railways incl. texturing and automatically calculated bridges.

pylons.py: Generates pylons and cables between them for power lines, aerial ways, railway overhead lines as well as street-lamps, wind turbines and storage tanks.

piers.py: Generates piers and boats.

platforms.py: Generates railway platforms.

All generated objects are added as static or shared objects to FlightGear scenery with correct elevation read on the fly from existing FlightGear scenery. Tagging and topology in OSM are respected as far as possible and complemented with some heuristics (given the developer team's origin mostly inspired by how stuff looks in Europe).
