[mapserver-users] RE: querying to getting bounding box coordinates

[David Hildebrand]

I wanted to retain WMS compatibility but the WMS protocol does not seem
to support attribute queries.  I know I can use GetFeatureInfo to get
attributes including the bounding box of the feature because these are
CGI variables.  However, GetFeatureInfo uses a spatial query (an image
point).  If I use MapServer's mode=itemquery what would be the URL
syntax and the requirements on the server side?  Would I be able to
specify or determine the projection?

Thanks for your help.

Are you limited to WMS/WFS or can you use stock MapServer queries?
Passing in
a parcel id and returning it's bounding box is trivial using
mode=itemquery and
a template.

I am running a WMS service with Mapserver in a Windows environment.  I
want to be able to run a non-spatial query on a parcel layer to return
the bounding box (in re-projected coordinates) for a particular parcel.
The bounding box and projection will then be used in a WMS query to
return a map image.

I've never coded server-side functionality with Mapserver so any
suggestions would be welcome.

Thanks to all.
