Switch to {{gitlab source}} to fix the broken Gitorious link and point to the current project, and removed the Gitorious scenery-france-850 link, replacing it with <s> tags as the repository no longer exists.

Dresden, Germany ([http://flightgear.org/forums/viewtopic.php?f=5&t=18851 EDDC]) and Innsbruck, Austria ([http://flightgear.org/forums/viewtopic.php?f=5&t=19625 LOWI]) have recently been populated with about 50,000 buildings derived from openstreetmap data. The buildings are textured with hi-res facade and roof images. While this certainly improves visual impression over the current random buildings, rendering a huge number of individual models in a scene is quite demanding. The FG process eats ~3GB RAM when flying in those areas, you might see a severe fps hit, and the download is ~50 MB each. However, the buildings respect LOD settings, and there's work underway to also reduce the memory footprint. | Dresden, Germany ([http://flightgear.org/forums/viewtopic.php?f=5&t=18851 EDDC]) and Innsbruck, Austria ([http://flightgear.org/forums/viewtopic.php?f=5&t=19625 LOWI]) have recently been populated with about 50,000 buildings derived from openstreetmap data.

The approach is similar to [[OpenStreetMap_buildings#Tools|bob.pl]] or forum user Soitanen's scripts, (or osm2xp for X-Plane), both of which have been [http://www.flightgear.org/forums/viewtopic.php?f=5&t=17598 discussed] in the forums. Being at a rather early stage of development, osm2city.py is currently not very user-friendly. You probably should know some python if you want to use it yourself. | ||
If you want to help out anyway: take pictures of buildings where you live! Radi is especially interested in south-east asian style architecture, as he's planning to populate Hong Kong Kai Tak (VHXX) in the future. But any other areas are welcome, too. There's a [[Howto:Create_textures_from_photos|howto]] on taking pictures ready for texture extraction. | If you want to help out anyway: take pictures of buildings where you live!

For people who like VFR flight it's a really nice scenery with lot of roads and rivers. Also this it give a good idea of the upcoming official scenery. | For people who like VFR flight it's a really nice scenery with lot of roads and rivers.
