Hello, Here is the area of Seattle in osm database, http://www.openstreetmap.org/?lat=47.642&lon=-122.237&zoom=9&layers=M The building coverage is poor, but the forests seems fine, how the map coverage compare to your xplane scenery? By the way there is a way to have Seattle fully covered with buildings, using a public state shapefile with osm2xp. It's a bit more hard to do than the "usual" but it's possible. here are a few screens of what you can get with this file (before/after - skycrappers are from a third party addon, seems it's from XsimReviews' Simmon) : http://images.osm2xp.com/seattle/1before.jpg http://images.osm2xp.com/seattle/1after.jpg http://images.osm2xp.com/seattle/2before.jpg http://images.osm2xp.com/seattle/2after.jpg I Think that the file i used is here : http://files.osm2xp.com/shapefiles/ Please note that i'm currently building a website that will distribute generated xplane scenery , and this kind of file will be available on it, but i can't give a release date. Regards Ben
