Thanks Andreas, for posting this, especially the picture here can illustrate how this works in Germany (and probably other areas): http://commons.wikimedia.org/wiki/File:Hinweisschilder_für_Hydrant_Wasser_und_Gas_102_2002.jpg For those of you not fluent in German here a short description: The white one with the red border is the sign interesting here (underfloor hydrant for the fire department, 100 is the diameter in mm, 13,7 is the horizontal distance in meters, 3,4 is the orthogonal distance in meters, measured from the sign position, "MVV Energie" is the operator (supposedly)). The blue and yellow sign are similarly describing the positions of the water and gas valve access points. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
