Thanks for letting me try out version 0.7.1. I processed the North America .pbf from geofabrik.de and all the landmarks are there. I live just south of San Francisco and it's nice to have realistic topography that I recognize.
Just getting back into Xplane 10 and World2Xplane looks fantastic. A big improvement over where Osm2Xp left off. I went to http://world2xplane.com/downloads/ , but the download is unavailable. Maybe a new version is going to be released or bandwidth limitations were reached?
