[Geomoose-users] GM 1.6 Identify subset of layer features

[Brian Welch]

Some bug-checking did catch a white space in my layer name in the XML file. That's now been fixed with an underscore so all the layer references match: XML file, layer map file and Identify.map file. I get the appropriate Identify results to appear, but they appear for ALL parcels, not just the college parcels. The attempt to add an expression that I pasted in my previous post had no effect on the results: the college data appears for Identify queries of ANY parcel.
 
Is there a way to get the Identify query to mirror the expression used to create the layer?
 
Thanks.

Brian,

  Couldn't you just use the same layer definition in your identify.map as you use in your display layer?

I have a layer in my application that shows a subset of parcels (local college-owned land). The mapping layer in GM uses a simple expression based on the property owner's name to map just those properties owned by the colleges.
 
I'd like to create an appropriate layer in the Identify.map file that will act only on that subset in order to display specific information related to the colleges. However, I don't want the college information to show up for all parcels in town. Is there some way to replicate the expression that I use in the CLASS call of the mapping file to get the LAYER in the Identify.map file to act only the college-owned parcels? I can't figure out whether the qstring_validation_pattern is where I should focus, and if so, what is the appropriate query syntax? The field name is [DEEDHOLD] and the query value would be "*COLLEGE" (note the need for a wildcard to pick up both colleges in town).
 
I'd like to know if this is possible by modifying the Identify.map layer with an appropriate query or whether I should just take the easy way out and create a separate shapefile of college-owned parcels.
 
Thanks.
