New Satellite Network to Provide High-definition Colored Videos of Earth
A network of satellites that can take high-resolution photos and colored videos of earth is planned. The images could be used in many ways. Videos could track moving vehicles and observe mining sites, while photos would make it possible for the construction of 3D models of the ground. The idea is to provide businesses and other groups with data to help them monitor certain activities or predict future events. VOA's Deborah Block reports.
