Actual OSM sceneries base on OSM data from geofabrik.de dated Sep 2012. Actual data – 5 months later – contains 10 – 20 percent more objects and corrected data.
If you update OSM data now you’ll see it in the next OSM scenery. Add your house, shopping center, school, whatever building you are missing and correct wrong data, forests, roads etc. on openstreetmap.org . I’ts easy and you help getting more and better OSM data. 🙂
