Alex Jarrett started the Degree Confluence Project project in February 1996 because he liked the idea of visiting a location represented by a round number such as 43°00'00"N 72°00'00"W. What would be there? Would other people have recognized this as a unique spot?
The Degree Confluence Project aims to visit each of the latitude and longitude integer degree intersections in the world, and to take pictures at each location. The pictures, along with a narrative describing the adventures it took to get there are then posted on this web site. This creates an organized sampling of the world.
Geoproject USA aims to to visit and photograph every spot in the U.S. where a whole-numbered minute of latitude intersects with a whole-numbered minute of longitude (e.g., 38°14'00"N, 109°55'00"W), in what is better known as a confluence point
