However, it can be time-consuming and costly to maintain. This study introduces automated algorithms and methods to support NWI maintenance. Through a wall-to-wall comparison between NWI and Coastal Change Analysis Program (C-CAP) datasets, a pixel-level difference product was generated at 1 m resolution. Building upon this, supplementary attributes describing wetland changes were incorporated into each NWI polygon. Additionally, new water polygons were extracted from C-CAP data, and regional statistics regarding wetland changes were computed for HUC12 watersheds. The 1 m difference product can indicate specific wetland change locations, such as wetland loss to impervious surfaces, the gain of open water bodies from uplands, and the conversion of drier vegetated wetlands to open water. The supplementary attributes can indicate the amount and percentage of wetland loss or water regime change for NWI polygons. Extracted new water polygons can serve as preliminary materials for generating NWI standard-compliant products, expediating NWI maintenance processes while reducing costs. Regional statistics of wetland change can help target watersheds with the most significant changes for maintenance, thereby reducing work areas. The approaches we present hold significant value in supporting NWI maintenance.<\/jats:p>","DOI":"10.3390\/rs15164075","type":"journal-article","created":{"date-parts":[[2023,8,18]],"date-time":"2023-08-18T09:13:44Z","timestamp":1692350024000},"page":"4075","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Use of High-Resolution Land Cover Maps to Support the Maintenance of the NWI Geospatial Dataset: A Case Study in a Coastal New Orleans Region"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1682-0893","authenticated-orcid":false,"given":"Zhenhua","family":"Zou","sequence":"first","affiliation":[{"name":"Department of Geographical Sciences, University of Maryland, College Park, MD 20742, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengquan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Geographical Sciences, University of Maryland, College Park, MD 20742, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Megan W.","family":"Lang","sequence":"additional","affiliation":[{"name":"U.S. Fish and Wildlife Service, National Wetlands Inventory, Falls Church, VA 22041, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2628-9557","authenticated-orcid":false,"given":"Ling","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Environmental Science & Technology, University of Maryland, College Park, MD 20742, USA"},{"name":"U.S. Department of Agriculture, Agricultural Research Service, Beltsville, MD 20705, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Greg","family":"McCarty","sequence":"additional","affiliation":[{"name":"U.S. Department of Agriculture, Agricultural Research Service, Beltsville, MD 20705, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey C.","family":"Ingebritsen","sequence":"additional","affiliation":[{"name":"U.S. Fish and Wildlife Service, National Wetlands Inventory, Madison, WI 53711, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nate","family":"Herold","sequence":"additional","affiliation":[{"name":"U.S. National Oceanic and Atmospheric Administration, North Charleston, SC 29405, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rusty","family":"Griffin","sequence":"additional","affiliation":[{"name":"U.S. Fish and Wildlife Service, National Wetlands Inventory, Madison, WI 53711, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weishu","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Geographical Sciences, University of Maryland, College Park, MD 20742, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaming","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Geographical Sciences, University of Maryland, College Park, MD 20742, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1080\/21513732.2015.1006250","article-title":"Ecosystem Services of Wetlands","volume":"11","author":"Mitsch","year":"2015","journal-title":"Int.
