[...] 在细读 flickr 的 post 三遍之后我还是不能理解Eric这些基于flickr照片的矢量图是如何制作出来的，本着求真务实的态度，我开始搜索 Eric 的信息，功夫不负有心人，终于大概知道这些矢量图的制作原理了 [...]

Thanks! It was done pretty much as you say — the pictures are all sorted by photographer and then by time, and for any two sequential pictures taken by the same person within 10 minutes and 3 miles of each other, there is a line drawn between the locations, with speed calculated from the distance and time deltas.

The API querying gets a little complicated because of the limits on the number of results you can receive at one time. With Flickr you can ask for a list for the whole world as long as you ask for a sufficiently short time range. Picasa does not let you limit queries by time, so you have to query for small areas to get any older results.

Yet again Eric Fischer kicks geospatial and urbanism ass and has his robotic assistant take names. I am curious about how this was done — is it just pairs of photos from the same source that are then strung together in a linestring and colored by distance between points divided by time apart they were taken? That is extremely elegant and clever. Do these photo site api’s let you query huge areas or do you have to do it in pieces?

Also agree that the representations of bodies of water are particularly cool, especially the Thames at its most trafficked part.

Thanks! I was surprised too how well it worked for the ferry routes.

these are awesome!! i love how boats show up on the map and play into the whole idea of mapping routes (even off the roads – really obvious to me on the SF one)!
