A user in Japan reported me that bug markers always shift about 50 meters west or east after submitting it. It does not depend on Browsers. From a sources, create-database.sql, OSB deals longitudes and latitudes as float value. Obviously, significant figures of them are small for areas of which longitude is over 100 degrees. The significant figure of float type is 6 digits, which means that the minimum unit of latitude is 0.001 degrees (about 100 m) in areas over 100 degree. It is useless to point a map feature. Could you increase precisions of latitude and longitude on database, to double type or int(10) type?
