NOAA Office for Coastal Management coastal bend Texas Benthic Habitat Mapping, 2006-2007 (NODC Accession 0070784)

In 2006 and 2007 the NOAA Office for Coastal Management (formerly the Coastal Services Center) purchased services to process existing digital multi-spectral imagery (ADS-40) and create digital benthic habitat data from this imagery for selected Texas coastal bend bays. The Center worked cooperatively with the Texas Parks and Wildlife Department (TPWD) and the Texas A and M University Center for Coastal Studies to develop benthic habitat data, primarily Submerged Aquatic Vegetation (SAV) for several coastal bays. This data will support the state's recently adopted Seagrass Monitoring Program which calls for regional mapping of SAV for status and trends assessment. The Center, Texas A and M, and TPWD have coordinated on the requirements of this project. Benthic habitat vector data was generated over eight Texas Coast study areas. The geographic extent of these regions is Corpus Christi Bay - app. 356 mi2, Redfish Bay - app. 62 mi2, Aransas Bay - app. 285 mi2, Copano Bay - app. 158 mi2, Lower Laguna Madre - app. 800 mi2, Upper Laguna Madre - app. 313 mi2, Baffin Bay - app. 232 mi2, and San Antonio Bay - app. 370 mi2. Benthic habitat data was generated for all estuarine lands below mean high water within the study area. No benthic data was required for the marine side of the barrier beaches. Data are GIS shapefiles with associated .dbf attribute tables and specific Federal Geographic Data Committee metadata for each study region. A generalized browse graphic was generated at the NODC for each region and included with these data.2006年至2007年，美国国家海洋和大气管理局（NOAA）海岸管理办公室（前身为海岸服务中心）采购服务，用于处理现有数字多光谱影像（ADS-40），并针对选定的得克萨斯州海岸湾域，从该类影像中提取生成数字底栖生境数据。该办公室与得克萨斯州公园与野生动物部（Texas Parks and Wildlife Department, TPWD）、得克萨斯农工大学海岸研究中心开展合作，为多个海岸湾域开发底栖生境数据，核心内容为沉水水生植被（Submerged Aquatic Vegetation, SAV）。本数据集将支持该州新近推行的海草监测计划，该计划要求开展沉水水生植被的区域制图，以进行现状与趋势评估。该中心、得克萨斯农工大学与得克萨斯州公园与野生动物部已就本项目的各项要求完成协调。 底栖生境矢量数据覆盖了得克萨斯州海岸的8个研究区域，各区域的地理范围分别为：科珀斯克里斯蒂湾（约356平方英里）、雷德菲什湾（约62平方英里）、阿兰瑟斯湾（约285平方英里）、科帕诺湾（约158平方英里）、下拉古纳马德雷湾（约800平方英里）、上拉古纳马德雷湾（约313平方英里）、巴芬湾（约232平方英里）以及圣安东尼奥湾（约370平方英里）。本数据集为研究区域内平均高潮线以下的所有河口陆地区域生成了底栖生境数据，屏障海滩的海洋一侧无需生成底栖数据。 本数据集采用地理信息系统（GIS）形状文件格式，附带.dbf属性表，且每个研究区域均配有专属的联邦地理数据委员会（FGDC）元数据。美国国家海洋数据中心（NODC）为每个区域生成了概览浏览图，并随本数据集一并提供。
