UN Mashups

Google has teamed with United Nations High Commissioner for Refugees (UNHCR) to create a Google Earth layer that shows refugees and displaced people located in Chad, Iraq, Colombia, and Darfur. There is a ComputerWorld article that links to this page at the UNHCR website.

The ComputerWorld article mentions three layers, a global layer, showing the various regions, a more geographic-specific layer discussing things like "refugee health, education, water and sanitation" and a local third layer about "schools and other infrastructure".
