ERDAS is providing access to datasets that illustrate the devastation in Japan after the 9.0 magnitude earthquake and the subsequent tsunami of March 11, 2011. This data is being supplied as a free web service that enables users to access various data. ERDAS will add new imagery, maps and vectors as they become available.
We now have pre- and post-earthquake images for Fukushima, which is the location of the compromised nuclear reactors, and Minamisanrikucho. The pre-earthquake imagery consists of GeoEye-1, half-meter resolution data collected on November 15, 2009. The post-earthquake imagery consists of IKONOS one-meter resolution data collected on March 12, 2011.
