Since then AWS has added all newly collected Landsat 8 images—some 700 images per day—within hours of their collection and processing by USGS. On Nov. 9 at the #SatSummit meeting in Washington, D.C., AWS’s Jed Sundwall shared that in the first 150 days of Landsat being on AWS over 500 million Landsat data requests had been made from around the globe.
AWS agreed to host up to one petabyte of Landsat data on its servers in support of the White House’s Climate Data Initiative. This allows researchers, scientists, cartographers, and data hobbyists to use cloud-computing to easily access and process large quantities of Landsat data.
Sundwall, writing for the Amazon Web Services Official Blog in March, stated “We hope to accelerate innovation in climate research, humanitarian relief, and disaster preparedness efforts around the world by making Landsat data readily available near our flexible computing resources.”
He added, “Because of Landsat’s global purview and long history, it has become a reference point for all Earth observation work and is considered the gold standard of natural resource satellite imagery.”
Note: The Landsat data requests include requests for imagery as well as imagery metadata.
+ More Ways to Get Landsat Data
More frequent satellite observations, such as those of the Harmonized Landsat Sentinel-2 (HLS) dataset, are needed to fully capture flood dynamics in regions experiencing short-lived, ephemeral flooding.
