Norbert,
I think I didn't make myself clear enough... I already have a
(JavaScript) function to measure distance in meters, feet, degrees, etc.
The problem is that I don't know in advance which units I should use. At
this moment I've hard-coded the correct units in my template file, but
I'd like the application to be general, so if I change the mapfile, or
the data, I shouldn't have to change anything else.
