Blue pictures are by locals. Red pictures are by tourists. Yellow pictures might be by either.

    These are true works of art. I mean that so much that I printed 3' squares of SF, NYC, and London (all cities that my wife and I have personal ties to) and hung them in my living room last night.

    I'm a few of those blue dots myself, I'll be more now that I have a camera with GPS.

    It would be interesting to do this for a city like New York City. As someone who lives in SF but has also lived in NYC my sense is that your algorithm would be more distinct in NYC. We get plenty of visitors in SF and end up taking them to the touristy places because it's easy, and we enjoy it. But I would not say the same about NYC. As a rule, we would avoid places like Times Square, The Statue of Liberty, McSorley's, etc... even if we had friends visiting from out of town. Tourists visiting a friend in NYC are much more likely to be absorbed into the local scene than the other way around.

    Oops. After I posted, I realized you had already done it. Hard to tell for sure but clearly statue of liberty is a red zone.

    WOW, it looks like most cities' East and West side. NICELY done

    Some food-for-thought:
    How about being a tourist in your own city?
    How about having "a local's mindset" when traveling?

    This is very cool.

    I can't tell how the colors are layered--only that they are opaque. It would be really cool to see this composed additively--so that each dot is maybe 10% R, G B--and let them add up. You would see more of the mixture/gradients of tourist/local... The really hot spots would just end up white... This would all need to happen over a black BG...

    How can you tell locals from tourists? I'm a photographer and wander around different parts of the city.

    @Galomorro3

    locals take photos over several months since they live there. tourists take photos just during a few days or a week while they are in town.

    you can download the large size from here and make a print yourself:

    ok, now, instead of diffing between locals and tourists, maybe you could parse out the dominant colors of all those photos, and color the map with the colors of the locations? maybe it'd just be all brown, but i'd wager the pics near water would be generally blue, and the mission would be very colorful, and the beach would be grey

    I've thought about trying to make one like that. The hardest part is that it takes a lot longer to download the images than it does just the location data, but it would ebe worth doing it for a small area and seeing what it looks like.

    That really interesting visually.

    Eric Fischer - are the lines links between the same photographer? (BTW, this is awesome stuff)
    magsatellite - I lived in the Bay Area for 35 years, and the only time I visited Alcatraz was when I was about 10, and my cousins came to visit.

  13. Eric Fischer 42 months ago | reply

    Yes, the lines are where the same photographer took multiple pictures near each other in space and time.

    I have made framed artworks out of these wonderful maps. If you can give me an email address, I am happy to share some photos of those.

    The use of yellow on white for "either" makes those points harder to see.
