Operational Land Imager (OLI)

The Operational Land Imager (OLI) is a sophisticated camera on NASA’s Landsat 8 satellite that captures detailed images of Earth's surface. It uses special sensors to detect sunlight reflected by land, water, and vegetation across various wavelengths, including those invisible to the human eye. This enables it to monitor environmental changes, such as deforestation, urban growth, and water quality, with high precision and resolution. OLI provides crucial data for scientists and policymakers to understand and manage natural resources, support agriculture, and study climate impacts.
