[Chameleon] Query and LegendTemplate Questions

[Robin Brown]

if I understand correctly, the first problem has a quick solution.  If you add the lines
as I have below, the layer will now be queryable.  The template is not used but that
allows the layer to be queried.  You don't have to have that file anywhere.  I believe
the tolerance and tolerance units are optional parameters.  Hope this helps.

As for the second problem, I do not know of any simple way to modify the output of the
query results.  Sorry.
