The terrain server approach is a good way of providing a regular geo- matrix of small, interpol-able scalar values.
Returning lists of hotspot coords and link URLs is of course quite possible and I imagine how the Panoramio and Wikipedia GMaps layers clicking works. Another way of using the terrain server would be to fetch all the tiles along a Polyline / Route so that its terrain profile could be obtained. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
