ImageCat uses remote sensing technology to identify impacted areas in South Asian Tsunami

January 2005 - A 9.0 earthquake off the coast of Sumatra triggered a massive Tsunami, killing over 100,000 people in Sri Lanka, India, Indonesia, Thailand and Malaysia. Because thousands of linear kilometers of remote beaches and villages were affected, response teams are relying heavily on remote sensing and GIS data.

In the image to the left, areas of potential devastation have been identified by cross referencing population data from NOAA's DMSP sensor (in yellow and orange) with wave height modeled by Vasily Titov at NOAA and proximity to the coastline. The resulting areas (in red) are being used to prioritize the acquisition of high-resolution images from DigitalGlobe.
