That sign should indicate where the hydrant really is, so it's
easier to locate.  I see no point in mapping where the sign is
and we should just map where the hydrant is instead.

For a proper meaning of the sign, in Dutch, see:
http://blog.seniorennet.be/westendseblik/archief.php?catID=1637

In short:
It has 2 numbers, indicating an x and y offset in meters
There is a letter, B for below ground, H for above ground
The B or H might be followed by a number indicting the
diameter
