My friends and collegues at International Center for Free and Open Source Software in Kerala, India have done a pretty interesting and massive mapping initiative over Thrissur Kole Wetlands. The wetlands are a massive 30,000+ acre area that are both important to wildlife and provide rice production.

Suman Rajan, Asish Abraham, and Deepthi Patric (left to right in image below) mapped 9000 acres of it.

Given the massive scale of the project, they ran it across multiple nodes using a cluster of computers coordinated by ClusterODM.

What a beautiful cluster, and an important and interesting project.
