Pi Day on Planet Earth


The best way to celebrate Pi day is to take a little tour of some of the many natural and human-made circles which can be found on planet Earth. Luckily Esri has created a World of Circles interactive map to help you find these beautiful landmarks of striking symmetry.

This Esri map contains aerial imagery of natural and human-made circles of various sizes, locations and origins. These circles include circular crop fields, thousand year old human earthworks, dormant volcanoes and even a defunct particle accelerator. If you would like to create a similar tour of interesting shapes then you can get started at Esri's Story Maps website.
