Degree Confluence Project The goal of this volunteer-run project is to post a photograph on this Web site of each of the 13,584 latitude and longitude degree intersections in the world (whole-number values only!). Confluences in the oceans and some near the poles have been excluded. There is a confluence point within 49 miles of wherever you're standing. You can join the fun with a camera and GPS receiver. Participants must create an account or log a plan Here's my question -- is this just a 21st Century collaborative learning oportunity, or is it pbl? Did I tag it right?
