To better understand what I am doing, consider this as an example (perhaps not very realistic, but close enough):
Let’s assume you have a site that allows the user to analyze cell phone coverage. Your database has the location of all the towers. Each tower contains various antenna types, each antenna type with a different range. Occasionally, new towers are added to the database, old towers are removed, and antenna types are changed. The user selects the antenna type, submits the request to the server, and the server generates the ellipses that represent each antenna’s coverage. Those ellipses are overlaid on the map and the image is returned to the user. The map image processing is all done server side via cgi requests. Sounds like the best way to do this might be to write out a unique shapefile for each user session. Certain user inputs (like a change in antenna type) will require their shapefile to be updated (rewritten), while other inputs (like zooming, panning, etc.) will not. Thanks again. If anyone knows of a better way to accomplish this, I'm all ears. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Dynamically-draw-different-sized-ellipses-on-map-tp5508425p5514639.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
