I stumbled across MapServer in my search for a tool to use in a website. I want to develop a website that will use a coordinate (lat & long), which is easily obtained from a user on the client side by clicking on a Google map, and then transferring this coordinate to the server side where it will be used to sequentially query many (500+) shapefile polygon layers, extracting the values from 2 fields from each layer at this coordinate, saving these values in a list (Excel, textfile?), and then using this list to return values to the user on the client side. This sounds simple in concept, but is MapServer a tool that can accomplish this and, if so, are there any examples showing the code to use for such a query?
