A while back i saw a map of london, made using data of people's daily journeys. Anyone know what I'm talking about?

Could it be this twitter-based map?

Any idea what kind of journeys?

Is it the UrbanDiary project?

Best answer: Do you mean http://www.openstreetmap.org/ ? It's made from GPS traces. Quite a remarkable project; but worldwide not just London.

Some people are doing interesting stuff with the data - e.g. analysing route choice by motorcycle couriers http://eprints.ucl.ac.uk/16229/1/16229.pdf

Best answer: I think I know what you're talking about. A guy did a trace of photos on Flickr and whether they were taken by locals or tourists and you could see in the result I think it was yellow for natives and red for tourists. Made for interesting viewing. Unfortunately I can't for the life of me remember where exactly I saw it, but that might give you something to go on.

Best answer: Biru is talking about Eric Fischer's maps made of geotagged Flickr photos.

Response by poster: These are interesting, but it wasn't any of these, it had a faint black line on a white background for every journey (i can remember what kind) and the lines built up to thicker darker lines where many journeys shared common routes. The combined effect was to create a map of london, which was darkest where there was the most activity
