The code is here: http://svn.openstreetmap.org/sites/rails_port/lib/geo_record.rb Seven fractional digits are saved. That should be somewhere in the 1-3 centimeter range depending on where you are and I believe that'll be enough for indoor mapping :) Lars _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
