[Chameleon] Querying Layers

[Darren.Cope@statcan.ca]

Hello Tracy,

Thanks for the help!  I finally got the query to work, after ensuring that
the DUMP, and TOLERANCE lines where set, and that each layer had a TEMPLATE.
However, it is also necessary, as I found out eventually, that the LAYER
NAME not have a space in it, as this will cause the queries to not work.
Even though I had everything right, and your "park" example worked fine for
me, my "provincial boundary" layer did not.  Replacing the space with an
underscore solved the problem though! Hopefully this will help out others
who may be having this problem.

Any way I can still use a space in the name (with an escape character of
some sort?)

Thanks!

Darren

Hi Darren, 

I had a similar problem..make sure you've got your tolerance units set as
well.

This is an example of one of my query layers.

LAYER
  NAME "Park"
  TYPE POLYGON
  DUMP TRUE
  TEMPLATE "blank.html"
  TOLERANCE 10
  TOLERANCEUNITS PIXELS
  STATUS ON
  GROUP "Municipal Park"
  DATA "Park"
  CLASS
  COLOR 150 231 138
  END
  METADATA
     WMS_TITLE "Park"
     WMS_ABSTRACT "Park"
  END
END

I've been trying to modify the output of the query results myself.  Right
now each record returns the Shape and ID items as well as the useful
attribute data.  I'm trying to suppress these fields.  If you happen to
figure it out would you mind letting me know!

Thanks, 

Tracy

Thanks for the suggestion Eric.  However, this does not seem to solve my
problem.

I'm new to this too, but I happen to have a guess.
You also need DUMP TRUE in your layer.
