comment Store GPS trace with timestamps, then interpolate location by time
@JohnBarça, yeah I'm not sure about that column. I suspect it's a seconds-since-epoch that matches the faulty 1970-01-01 date in the other table. So 011806.0 (not 118806) is about 3am UTC, or around 2pm local time (Victoria, Australia). (The two fragments I quoted don't correspond exactly.)

Thanks! Yeah, pre-processing the image would almost certainly require server-side processing, which just makes everything a bit more complicated.

Ha! Yes, that looks exactly right. I didn't think of looking in Leaflet itself - thought it would require something more. Make your comment an answer and you win the prize..

Thiessen polygons also seem to be the same thing as Voronoi Polygons? They make an assumption that all places are equal, of course. Can see lots of cases where they wouldn't be. There's this great visualisation of nearest coffee shops in some US city (I can't find it), which would be exactly what I want if it had an additional factor of attractiveness of each coffee shop.

Thanks @martinf. If you make that an answer, I can accept it...

I tried doing a sketch, but it was actually pretty hard to make anything that looked at all right.

@Vince, really? I've explained in quite a lot of detail exactly how the visualisation would work. Are you asking for a hand drawn sketch or something? What extra information would you like?
