Landsat data is available for download from EarthExplorer for the conterminous United States, Alaska, and Hawaii referenced using the WGS84 datum and provided as GeoTIFF data
3.1-Trillion Pixel Landsat 8 Mosaic of the World
Descartes Labs has compiled some of the massive amount of data sent back from the satellites orbiting Earth into a 3.1-trillion pixel composite image of Earth’s surface.
Advances in Landsat Sensors
Since those first images in 1972, multiple Landsat satellites have been launched with the ability to take increasingly detailed pictures of our world.
Landsat 9 Will Launch in 2020
The Landsat series of satellites has been imaging the Earth’s surface for nearly 50 years, providing vital imagery for a range of purposes from the natural sciences to civil administration and conflict monitoring. NASA and the USGS recently announced that the next iteration of the program, Landsat 9, is due to launch in 2020.
Use of Earth Observation Data for Oil and Gas
Andrew Cutts, owner of ACGeospatial, discusses the role of GIS and earth observation data in the oil and gas industry in this guest article.
Using Landsat Imagery to Find Shipwrecks
Satellite imagery from Landsat 8 has been used by a Belgian marine research institute to detect shallow water shipwrecks. Satellite imagery from Landsat 8 can detect the concentration of sand and silt particles in the ocean, which can then be used to pinpoint a potential shipwreck location.
Cloud Computing Used to Analyze Landsat Imagery and Detect Deforestation
Landsat, NASA’s longest running initiative for the acquisition of Earth imagery, has generated nearly 50 trillion pixels of data by capturing one image per season, of every place on Earth, for the past 43 years, providing a treasure trove of data for researchers.
River Width GIS Data Created from 1,756 Landsat Images
Researchers used 1,756 Landsat images to develop a GIS database of river widths for the entire North American continent.
