Background information: we'd rather not publish the exact geo-coordinates the hosts put in, because of privacy concerns. So what we do now is that whenever we display probes on a map, we round the geo-coordinates to two digits. This introduces a "random" error of up to 1000 meters or so. (If you zoom in on Amsterdam, where we have enough probes, you'll see that all probes are aligned into a neat, sparse matrix; it's because of this.)
It seems to be relatively easy to round the geo-coordinates to two digits (as you do it right now) and then add some random number from 0.00000 to 0.00999 to it.
Yes, but it would also make the probes dance around at each page load. I'm sure it would be entertaining, but not so sure about the usefulness :-)
I was rather thinking about some random, but fixed (put into database) number for each probe. OTOH it would be nice to see a movie from such a dance. ;-) Piotr -- gucio -> Piotr Strzyżewski E-mail: Piotr.Strzyzewski@polsl.pl
