Geostationary imagery layers are also now available. View current natural hazards and events using the Events tab which reveals a list of natural events, including wildfires, tropical storms, and volcanic eruptions. This supports time-critical application areas such as wildfire management, air quality measurements, and flood monitoring. Many of the imagery layers are updated daily and are available within three hours of observation - essentially showing the entire Earth as it looks "right now". Landsat 9, like Landsat 8, is both radiometrically and geometrically better than earlier generation Landsats.The Worldview tool from NASA's Earth Observing System Data and Information System ( EOSDIS) provides the capability to interactively browse over 1000 global, full-resolution satellite imagery layers and then download the underlying data. Landsat 9, like Landsat 8, has a higher imaging capacity than past Landsats, allowing more valuable data to be added to the Landsat global land archive-around 1,400 scenes per day. The combined Landsat 8 + Landsat 9 revisit time for data collection with be every 8 days, like it currently is for Landsat 8 + Landsat 7. Landsat 9 replaces Landsat 7 (launched in 1999), taking its place in orbit (8 days out of phase with Landsat 8). Landsat 9, launched September 27, 2021, joins Landsat 8 in orbit the satellite orbits are 8 days out of phase. Landsat 9 will collect data at the same rate as Landsat 8. Landsat 8 has added more data per year than any proceeding satellite. archive contributed by each Landsat satellite as of Sept.
Sustainable Land Imaging Program, Landsat 9 has a design very similar to Landsat 8’s which allowed the Landsat 9 build and launch to be expedited. Since reducing the risk of a Landsat data gap is a high priority of the U.S. Image credit: USGS/NASA More data | Better data Landsat 9 now collects data at the same rate as Landsat 8.
