A degree confluence is the intersection of longitude and latitude lines. For example, the closest confluence to Vancouver, B.C. is 49°N 123°W (in Boundary Bay) and the closest land-based confluence is 49°N 122°W (on the Canada-U.S. border near Abbotsford). The project to document them all on the web is big enough of a deal to have its own Wikipedia page. Since confluences of latitude and longitude have mostly been documented, Charlie Loyd set out to document microconfluences, which he defines as the intersections of hundredths of latitude and longitude points. I found this out after stumbling on his tweet late 2013. An example in Toronto, Canada is the microconfluence of 43.6700°N -79.3800°W at St. Charles E. and Mt. Pleasant Rd. The trailing zeroes are important because they show the precision of the hundredth of a latitude and longitude point.

To find microconfluences, Charlie built a web page you can load up in your phone pointing out your current location and how far away from and which direction to find the nearest microconfluence. I found my first microconfluence in my hometown of Courtenay, British Columbia over the Christmas holidays. I could only get as close as the front door of a new housing development on Piercy Ave., taking a photo of my iPhone's screen with my iPad mini. I take screenshots of Charlie's web page (indicating the GPS coordinates) with a photograph of something notable next to the screenshot.
