Revision History for FS 2021-3035 U.S. Geological Survey South Dakota and Landsat ----------------------------------------------------- Posted online June 16, 2021 ----------------------------------------------------- Revised and reposted February 22, 2023, version 1.1 The text version was modified. In the second paragraph on p. 1, text was modified from "Tens of thousands of visitors each year descend upon its rolling fields and grasslands to seek a shotgun audience with the State bird, the Phasianus colchicus (Linnaeus, 1758) (ring-necked pheasant), or with the waterfowl of northeastern South Dakota’s prairie pothole region." to "Tens of thousands of visitors each year descend upon its rolling fields and grasslands to hunt the State bird, the Phasianus colchicus (Linnaeus, 1758) (ring-necked pheasant), or the waterfowl of northeastern South Dakota’s prairie pothole region. In the "Mapping South Dakota Croplands" section, an in-text citation was changed from "Savoka and others, 2013" to "Savoca and others, 2013." Another in-text citation was changed from "FSA, 2019" to "Farm Service Agency, 2020." In the "Watching South Dakota's Wetlands" section, "nearly" was removed from "nearly 50 years." In the "Protecting South Dakota Forests" section, an in-text citation was changed from "USDA, 2020" to "Forest Service, 2020." In that same section, "though" was changed to "through" in "scenic drives though Custer State Park." In the "Landsat--Critical Information Infrastructure for the Nation" section, the first three paragraphs were modified from "Landsat is the most widely used land remote sensing data source within Federal civilian agencies. Local, State, and Federal agencies use Landsat to monitor and forecast a wide range of land surface phenomena. Information from Landsat contributes to day-to-day decisions on land, water, and resource use that protect life and property; safeguard the environment; advance science, technology, and education; and grow the U.S. economy. Landsat’s imagery provides a landscape-level view of land surface, inland lake, and coastal processes, both natural and humaninduced. Landsat enables us to better understand the scope, nature, and speed of change to the natural and built environment. Businesses draw upon Landsat data to provide customer-specific applications to improve logistics, resource allocation, and investment decisions. Commercial space imaging firms leverage Landsat data to refine product offerings and support new information services. A 2017 USGS study determined the total annual economic benefit of Landsat data in the United States to be $2.06 billion, far surpassing its development and operating costs. Landsat 7 and Landsat 8 provide 8-day repeat coverage of the Earth’s land surfaces. Landsat 9, which will replace the aging Landsat 7, is under development for launch in 2021. The National Aeronautics and Space Administration (NASA) and the USGS are currently reviewing the findings from a joint Architecture Study Team, which will inform the design and implementation approach for Landsat Next, the follow-on mission to Landsat 9. Landsat 9 and its successors will provide a sustainable, space-based system to extend the nearly 50-year Landsat series of high-quality global land imaging measurements--the world’s longest time series of the Earth’s land surface." to "Landsat is the most widely used land remote sensing data source within Federal civilian agencies.
