Revision History for FS 2020-3065 U.S. Geological Survey Ohio and Landsat ----------------------------------------------------- Posted online December 21, 2020 ----------------------------------------------------- Revised and reposted September 19, 2022, version 1.1 The State image on p. 1 was changed from a Landsat 7 image to a Landsat 8 image. In the first paragraph, "gypsy moth" was changed to "spongy moth" and the Latin name and authorship were moved to this first mention. In the "Flooding Events" section, the text was modified to be one paragraph instead of bullet points, "enables" was changed to "enable," and the in-text citation "Patel, 2014" was added. In the "Monitoring Dangerous Algal Blooms" section, the in-text citation "Carnegie Institution for Science, 2017" was added. In the "Spongy Moth Defoliation" section, all instances of "gypsy moth" were changed to "spongy moth." "Defoliation" was changed to "wide-scale defoliation" in the first sentence. "Dramatically" was changed to "drastically." The final sentence in the section was changed from "Using Landsat to help identify where wide-scale defoliation was taking place, Ohio developed a plan in 1998 to stem the moths’ movement westward and continues using it today (2020)." to "Ohio developed a plan in 1998 to stem the moths’ movement westward, and researchers demonstrated Landsat’s ability to locate areas of defoliation across the State for targeted treatment (Hurley and others, 2004)." The final figure on p. 2 was modified so that an image of a tree behind a string of power lines was removed. The caption was updated to change "credits" to "credit" and to change "gypsy moth" to "spongy moth." In the "Landsat--Critical Information Infrastructure for the Nation" section, the sentence "Local, State, and Federal agencies use Landsat to monitor and forecast a wide range of land surface phenomena." was changed to "Local, State, Tribal, and Federal agencies use Landsat to monitor and forecast a wide range of land surface phenomena." In the second paragraph of this section, "space imaging" was hyphenated and the in-text citation "Straub and others, 2019" was added. The third paragraph was changed from "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 8 and Landsat 9 provide 8-day repeat coverage of the Earth’s land surfaces. 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 are planned to provide a sustainable, space-based system to extend the 50-year Landsat series of high-quality global land imaging measurements—the world’s longest time series of the Earth’s land surface." A "References Cited" section was added.
