[Chameleon] Query Results

[Rene Teniere]

Hi Tracy, here is an example map file. You have to set the tolerance on
it so that the query will pick up the features:

  LAYER
    NAME "Forest"
    GROUP "Forest Type"
    STATUS ON
    TEMPLATE "c:/chameleon11a/websites/template/blank.html"
    TYPE POLYGON
    MAXSCALE 500000
    TILEINDEX "D:/GIS_Data/coindex/coindex"
    TILEITEM "loforest"
    CLASSITEM "COVER_TYPE"
    TOLERANCE 10
    TOLERANCEUNITS PIXELS
    CLASS
      NAME "Softwood"
      EXPRESSION "2"
      STYLE
        SYMBOL 0
        COLOR 33 66 0
        SIZE 1
        MINSIZE 1
        MAXSIZE 100
      END
    END
    CLASS
      NAME "Mixwood"
      EXPRESSION "5"
      STYLE
        SYMBOL 0
        COLOR 33 99 33
        SIZE 1
        MINSIZE 1
        MAXSIZE 100
      END
    END
    CLASS
      NAME "Hardwood"
      EXPRESSION "8"
      STYLE
        SYMBOL 0
        COLOR 100 50 0
        SIZE 1
        MINSIZE 1
        MAXSIZE 100
      END
    END
  END

Good Luck!

Hello,

I have my Query Tool working in principle but I can't actually get it
to
return any information.  I have put the DUMP, TEMPLATE and STATUS (on)
variables in my mapfile and all shapefiles have an attribute table. 
When I
click on any one of them using my Information tool I just get 'no
results
returned for...'.  How can I tell Chameleon which fields to return?  

Also, what if I have a URL that I'd like to link to in the results
table -
can I have a field which is displayed and then another field which
actually
contains the link without having to show it?  For example I want the
query
results to say 'click here for more info' and then link to a url which
is
stored in the associated dbf of the shapefile.

As always your thoughts are much appreciated.

Tracy

Jeff,

The demo uses a map that is in a non standard EPSG projection.

Find your PROJ's "epsg" file (Most likely in /usr/local/share/proj/),
and
add the following at the bottom:

# WGS84 Canada LCC (WARNING: FAKE EPSG CODE, NON STANDARD) 
<42101> +proj=lcc +ellps=WGS84 +lat_0=0 +lon_0=-95 +lat_1=49 +lat_2=77
+x_0=0 +y_0=-8000000 +datum=WGS84 +units=m no_defs <>
# NAD83 Canada LCC (WARNING: FAKE EPSG CODE, NON STANDARD) (This is
the
standard Atlas of Canada data's projection)
<42304> +proj=lcc +ellps=GRS80 +lat_0=49 +lon_0=-95 +lat_1=49
+lat_2=77
+datum=NAD83 +units=m no_defs <>

(There's 2 common canadian projections here, forget exactly which one
the
demo uses)

I've installed Chameleon 1.1 on Redhat 8.0, running MapServer 4.0.1. 
I'm
having real trouble getting the demo app to work.  I have chameleon
installedin /opt/cwc2.  I've installed all the demo documents within
the
appropriate directories under /opt/cwc2, and have edited the config,
index.phtml and map document to refelct paths correctly.  However, when
I
try to open the index.phtml I get the following error:

Warning: [MapServer Error]: msProcessProjection(): no options found in
'init' file in /opt/cwc2/htdocs/common/wrapper/map_session.php on line
215

Warning: Failed to open map file /opt/cwc2/map/chameleon.map in
/opt/cwc2/htdocs/common/wrapper/map_session.php on line 215
ERROR: Invalid map file file (/opt/cwc2/map/chameleon.map).
Fatal error: Call to a member function on a non-object in
/opt/cwc2/htdocs/widgets/KeyMap.widget.php on line 190

Any suggestions?
