Historically, NHD flow lines were created by digitizing surface water information from aerial photography and paper maps. Using these same methods to update nationwide NHD flow lines is costly and inefficient; furthermore, these methods result in hydrography that lacks the horizontal and vertical accuracy needed for fully integrated datasets useful for mapping and scientific investigations. Effective methods for improving mapped hydrography employ change detection analysis of surface channels derived from light detection and ranging (LiDAR) digital elevation models (DEMs) and NHD flow lines. In this article, we describe the usefulness of surface channels derived from LiDAR DEMs for hydrography change detection to derive spatially accurate and time-relevant mapped hydrography. The methods employ analyses of horizontal and vertical differences between LiDAR-derived surface channels and NHD flow lines to define candidate locations of hydrography change. These methods alleviate the need to analyze and update the nationwide NHD for time relevant hydrography, and provide an avenue for updating the dataset where change has occurred.", "description": "19 p.", "publisher": { "@type": "Organization", "name": "American Water Resources Association" }, "author": [ { "@type": "Person", "name": "Worstell, Bruce B. worstell@usgs.gov", "givenName": "Bruce B.", "familyName": "Worstell", "email": "worstell@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-8927-3336", "url": "https://orcid.org/0000-0001-8927-3336" }, "affiliation": [ { "@type": "Organization", "name": "Earth Resources Observation and Science (EROS) Center (Geography)", "url": "https://www.usgs.gov/centers/eros" } ] }, { "@type": "Person", "name": "Gesch, Dean B. gesch@usgs.gov", "givenName": "Dean B.", "familyName": "Gesch", "email": "gesch@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-8992-4933", "url": "https://orcid.org/0000-0002-8992-4933" }, "affiliation": [ { "@type": "Organization", "name": "St. Petersburg Coastal and Marine Science Center", "url": "https://www.usgs.gov/centers/spcmsc" }, { "@type": "Organization", "name": "Earth Resources Observation and Science (EROS) Center (Geography)", "url": "https://www.usgs.gov/centers/eros" }, { "@type": "Organization", "name": "Earth Resources Observation and Science (EROS) Center", "url": "https://www.usgs.gov/centers/eros" } ] }, { "@type": "Person", "name": "Poppenga, Sandra K.", "givenName": "Sandra K.", "familyName": "Poppenga", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2846-6836", "url": "https://orcid.org/0000-0002-2846-6836" } } ], "funder": [ { "@type": "Organization", "name": "Earth Resources Observation and Science (EROS) Center", "url": "https://www.usgs.gov/centers/eros" } ] }, "OpenAlex": { "abstract_inverted_index": { "Abstract:": [ 0 ], "The": [ 1, 136 ], "1:24,000\u2010scale": [ 2 ], "high\u2010resolution": [ 3 ], "National": [ 4 ], "Hydrography": [ 5 ], "Dataset": [ 6 ], "(NHD)": [ 7 ], "mapped": [ 8, 86, 134 ], "hydrography": [ 9, 63, 87, 125, 158 ], "flow": [ 10, 29, 52, 108, 151 ], "lines": [ 11, 30, 53, 152 ], "require": [ 12 ], "regular": [ 13 ], "updating": [ 14, 181 ], "because": [ 15 ], "land": [ 16 ], "surface": [ 17, 21, 35, 93, 118, 147 ], "conditions": [ 18 ], "that": [ 19, 64 ], "affect": [ 20 ], "channel": [ 22 ], "drainage": [ 23 ], "change": [ 24, 89, 126, 185 ], "over": [ 25 ], "time.": [ 26 ], "Historically,": [ 27 ], "NHD": [ 28, 51, 107, 150, 171 ], "were": [ 31 ], "created": [ 32 ], "by": [ 33 ], "digitizing": [ 34 ], "water": [ 36 ], "information": [ 37 ], "from": [ 38, 96, 121 ], "aerial": [ 39 ], "photography": [ 40 ], "and": [ 41, 56, 68, 79, 99, 106, 132, 142, 149, 167, 176 ], "paper": [ 42 ], "maps.": [ 43 ], "Using": [ 44 ], "these": [ 45, 59 ], "same": [ 46 ], "methods": [ 47, 60, 83, 137, 161 ], "to": [ 48, 128, 153, 165 ], "update": [ 49, 168 ], "nationwide": [ 50, 170 ], "is": [ 54 ], "costly": [ 55 ], "inefficient;": [ 57 ], "furthermore,": [ 58 ], "result": [ 61 ], "in": [ 62 ], "lacks": [ 65 ], "the": [ 66, 115, 163, 169, 182 ], "horizontal": [ 67, 141 ], "vertical": [ 69, 143 ], "accuracy": [ 70 ], "needed": [ 71 ], "for": [ 72, 77, 84, 124, 172, 180 ], "fully": [ 73 ], "integrated": [ 74 ], "datasets": [ 75 ], "useful": [ 76 ], "mapping": [ 78 ], "scientific": [ 80 ], "investigations.": [ 81 ], "Effective": [ 82 ], "improving": [ 85 ], "employ": [ 88, 138 ], "detection": [ 90, 98, 127 ], "analysis": [ 91 ], "of": [ 92, 117, 140, 157 ], "channels": [ 94, 119, 148 ], "derived": [ 95, 120 ], "light": [ 97 ], "ranging": [ 100 ], "(LiDAR)": [ 101 ], "digital": [ 102 ], "elevation": [ 103 ], "models": [ 104 ], "(DEMs)": [ 105 ], "lines.": [ 109 ], "In": [ 110 ], "this": [ 111 ], "article,": [ 112 ], "we": [ 113 ], "describe": [ 114 ], "usefulness": [ 116 ], "LiDAR": [ 122 ], "DEMs": [ 123 ], "derive": [ 129 ], "spatially": [ 130 ], "accurate": [ 131 ], "time\u2010relevant": [ 133 ], "hydrography.": [ 135 ], "analyses": [ 139 ], "differences": [ 144 ], "between": [ 145 ], "LiDAR\u2010derived": [ 146 ], "define": [ 154 ], "candidate": [ 155 ], "locations": [ 156 ], "change.": [ 159 ], "These": [ 160 ], "alleviate": [ 162 ], "need": [ 164 ], "analyze": [ 166 ], "time": [ 173 ], "relevant": [ 174 ], "hydrography,": [ 175 ], "provide": [ 177 ], "an": [ 178 ], "avenue": [ 179 ], "dataset": [ 183 ], "where": [ 184 ], "has": [ 186 ], "occurred.": [ 187 ] }, "apc_list": { "value": 3000, "currency": "USD", "value_usd": 3000, "provenance": "doaj" }, "apc_paid": { "value": 3000, "currency": "USD", "value_usd": 3000, "provenance": "doaj" }, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5069753971", "display_name": "Sandra K.
