Google Map - MapServer and WMS II

Sep4

Written by:Steve White
Monday, September 04, 2006 

After a few tests with WFS and parsing the GML it looked like it put too much load on the client, so we tried a different approach. We loaded the WMS as normal and then captured the point where a user clicks and sent this point and other paramters back to MapServer as a GetFeatureInfo request.

This returns HTML back to the map which I then load into the InfoWindow.

Here's the outcome of the GetFeatureInfo test:

Click on 'Military Roads', wait for the layer to load, then click on any polyline.
