Thanks for looking at my "everybody heatmap" folks. I know it is not perfect by any means: 1) you have to make your rides fully public so that I can see what tiles you have been to. Then after you've done that 2) I have to do an offline process to download everyone's data and merge into one map, so you don't get instant gratification of getting the map filled in. Then 3) the number of squares filled in is so massive that web browsers start to creak with the amount of memory needed to display it.
On the other hand, it is quite a fun map to look at.
I'm hopeful that Ben will provide an API that will fix some/all of these issues, but if you have other ideas on where to go with it, I'd be interested to hear.
Also, are there any other "impossible" squares that should be coloured in red?
Thanks,
Pete
