Landsat represents the world’s longest continuously acquired collection of space-based moderate-resolution land remote sensing data.
“Landsat sensing is the science and art of obtaining information about an object, area, or phenomenon through the data acquired by a device that is not in contact with the object, area, or phenomenon under investigation.”
Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. On May 30, 2013, data from the Landsat 8 satellite became available. As with previous partnerships, this mission continues the 40 year acquisition of high-quality data the meet both NASA and ASGS scientific and operational requirements for observing land use and land change.
