Thanks Andreas, for posting this, especially the picture here can
illustrate how this works in Germany (and probably other areas):
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.
