Data inputs include Light Detection and Ranging Data, State and Federal Wetland Inventories, soils, and field data. Because the map was conservative in its wetland predictions, NYC Parks staff improved the map through a series of desktop and field verification efforts beginning in 2020.The map will be opportunistically updated depending on available information.\n\nThis dataset was developed to increase awareness regarding the location and extent of wetlands to promote restoration and conservation in New York City. This map does not supersede U.S. Fish and Wildlife Service National Wetlands Inventory (NWI) and New York State Department of Environmental Conservation (NYSDEC) wetlands maps and has no jurisdictional authority. It should be used alongside NWI and NYSDEC datasets as a resource for identifying likely locations of wetlands in New York City. Mapped features vary in the confidence of their verification status, ranging from \"Unverified\" (meaning the feature exists in its original remotely mapped form and has not been ground truthed) to \"Verified - Wetland Delineation\" (meaning the boundaries and type of wetland have been verified during an official wetland delineation). Because of the rapid nature of the protocol and the scale of data collection, this product is not a substitute for on-site investigations and field delineations. The dataset also includes broad classifications for each wetland type, e.g. estuarine, emergent wetland, forested wetland, shrub/scrub wetland, or water. Cowardin classifications were not used given rapid verification methods.\n\nThe accuracy of the wetlands map has improved over time as a result of the verification process. Fields were modified over time as necessitated by the workflow and values were updated with information, either from the field verifications, delineation reports, construction designs, or desktop reviews.\n\nHttps://www.nycgovparks.org/greening/natural-resources-group \n\nData Dictionary:\nHttps://docs.google.com/spreadsheets/d/1UyJssBTcWSOzfOpP2r45ok_s3wZlc6RQ/edit?usp=sharing&ouid=100172030647057411202&rtpof=true&sd=true \n\nMap:\nhttps://data.cityofnewyork.us/dataset/NYC-Wetlands/7piy-bhr9", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://data.cityofnewyork.us/api/views/p48c-iqtu/rows.csv?accessType=DOWNLOAD", "mediaType": "text/csv"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofnewyork.us/api/views/p48c-iqtu/columns.rdf", "describedByType": "application/rdf+xml", "downloadURL": "https://data.cityofnewyork.us/api/views/p48c-iqtu/rows.rdf?accessType=DOWNLOAD", "mediaType": "application/rdf+xml"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofnewyork.us/api/views/p48c-iqtu/columns.json", "describedByType": "application/json", "downloadURL": "https://data.cityofnewyork.us/api/views/p48c-iqtu/rows.json?accessType=DOWNLOAD", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofnewyork.us/api/views/p48c-iqtu/columns.xml", "describedByType": "application/xml", "downloadURL": "https://data.cityofnewyork.us/api/views/p48c-iqtu/rows.xml?accessType=DOWNLOAD", "mediaType": "application/xml"}], "identifier": "https://data.cityofnewyork.us/api/views/p48c-iqtu", "issued": "2024-12-06", "landingPage": "https://data.cityofnewyork.us/d/p48c-iqtu", "modified": "2026-01-06", "publisher": {"@type": "org:Organization", "name": "data.cityofnewyork.us"}, "title": "NYC Wetlands"}
