Query in multiple layers

[Steve Lime]

How you do something like this depends on how you want the end product to look and what technologies you're willing to use to get there. There is no way to do this with a single query. Using MapScript will certainly work and allows everything to be done on the server-side. Alternatively you could use AJAX to get at the properties of the points, stuffing the subsequent results into a div below the line information. Could perhaps even IFRAMEs in the template to display the sites where the source of each IFRAME is a MapServer query. I would think the MapScript approach would be the most straight forward.
