TerraLook Version 2.0 (beta) software released

Press Release. 24 January 2011

TerraLook provides easy access to new and historical satellite images for users that lack experience with satellite images, or for anyone looking for a convenient way to obtain and work with these images. Formerly known as the Protected Area Archive, TerraLook combines collections of georeferenced JPEG images with simple visualization and analysis tools to help users explore and utilize the data, and all data are free. The US Agency for International Development (USAID) funded this latest TerraLook upgrade through SERVIR— the Regional Visualization and Monitoring System— an initiative representing a partnership between USAID, the US National Aeronautics and Space Administration (NASA), and numerous other organizations. You are invited to test the newest beta version of TerraLook software, Version 2.0 (beta), and to report on your experiences.
