Satellites designed to document our planet over time provide us with valuable information about the impact of human activity, natural disasters and climate change. The Landsat Program has changed the way we look at our planet. An entire new field for scientific study and practical applications had emerged: remote sensing.
Today, the Landsat program has accumulated over 1.7 million scenes and over 630 terabytes of data (one terabyte is equivalent to 109 DVD movies). The archive grows by over 320 gigabytes every day.
The Future of Operational Land Imaging Working Group is leading an effort to develop a long-term plan to achieve technical, financial, and managerial stability for operational land imaging in accord with the goals and objectives of the U.S. Integrated Earth Observation System.
