When serving up large data sets such as mobile coverage maps (custom tile) mashed up with MapQuest maps and MapQuest POIs, is there any performance benefit to using shapefile vs WMS image PNGs?

The controls on the map appear to be OpenLayers.

Here's how you can find out yourself what kind of data it's using in the client in Chrome or Firefox:

  • In Chrome, go to Menu > Tools > Developer Tools and switch to the Network tab.
  • In Firefox, go to Menu > Developer > Network
  • Refresh the page, pan around the map a few times, see what resources load.
  • Hint: it's not sending any vector data to the client at all. – Jason Scheirer Jul 2 '14 at 14:04
