Next time you want to quickly and easily throw a heatmap over a Google Map, you might want to check out “heatMAP” from Differential Enterprises. A simple tool that can pull lat/long and value data from any HTTP Post request (and many other sources), it makes the entire process trivial.
The user (or web developer) has control over
- blending level (local vs. large-region smoothing)
- granularity of the color cells
- other useful display parameters.
It’s still in it’s infancy but pretty functional. Works best in FireFox, but they’re working on better IE support.
