[Mapserver-users] Measure tool

[Palle Due Larsen]

Hi,

You can easily achieve that with javascript. Use the cellsize template
parameter like this:

var cellsize= [cellsize];

Compute the distance between the two points in pixels, and multiply by
the cellsize.

As for how to get a mouse click from dbox, I'm not quite sure, but that
should be fairly easy.

Best regards
