That way you can handle bigger sets of data and dramatically boost load times. It should be out in a couple of days or so. But considering how much data you have you could probably remove a lot of the coordinates before even starting to encode it. P.S I had to look up lakh in Wikipedia, I didn't know that it means 100.000 :-) /Gabriel @Venkat: Keep your eyes open for my upcoming article about how to encode a polyline on the server.

I had completely missed that. It's now corrected in the example. Apparently there's some extra space at the bottom of the map in IE6, so using bottom as a reference in the CSS wasn't that good. On the other hand it was easily fixed by changing the position to be relative to the top instead. Using a sprite seems like a smart thing to do. I'm looking forward to see what you come up with! /Gabriel I’m glad that you found the article useful! :-)
