Temecula, California is well known for its climate, hot-air ballons, numerous golf courses, popular wineries within the eastern countryside, an active historic downtown, and gateway to "Little Las Vegas" (aka Pechanga Resort) at the Pechanga Indian Reservation.
Between last summer 'til now, portions of the OSM map of Temecula have turned from a simple collection of white TIGER street imports into one of the most detailed free maps of Temecula. OSM perhaps now has the most current map layout of the road network within the massive Pechanga Resort and Casino. Much work still needs to be done!
The developing detailed map is and will be done mainly through tracing the Yahoo imagery combined with local knowledge, recording data while riding the roads as a passenger, and conducting detailed surveys.
