NODC Standard Product: C-CAP Coastal Change Analysis Project - St. Croix estuary region (1985 - 1992) (NODC Accession 0090142)

The Coastal Change Analysis Project St. Croix Estuary Region CD-ROM data set uses Landsat Thematic Mapper (TM) imagery from 1985 to 1992 to provide a regional change analysis of the St. Croix Estuary and Passamaquoddy Bay in Maine and Canada. This project was a cooperative effort involving the U.S. Fish and Wildlife Service, the Gulf of Maine Program and Environment Canada. The CD-ROM was produced with the cooperation of the NOAA Coastal Ocean Program's Estuarine Habitat Studies Program, the National Marine Fisheries Service, the National Oceanographic Data Center, and the National Geophysical Data Center.

Steady increases in coastal development bring with it non-point source pollution, erosion and other environmental threats. In an effort to improve our understanding of these changes, the C-CAP program has strive to develop a nationally accepted standard protocol for monitoring land cover and habitat changes for coastal regions of the U.S. The St. Croix Estuary is the second release in this series of CD-ROM datasets. Historically valuable as a habitat for salmon, this area is now threatened by changes from the large Maine and Canadian forestry industries. Understanding where and how these changes are occurring is important for sound resource management decisions.

The St. Croix Estuary product consists of three parts: (1) a 1985 land cover analysis, (2) a 1992 land cover analysis, and (3) a land cover change detection analysis, all in binary raster format. These data are in Universal Transverse Mercator (UTM) coordinate system and are not explicitly georeferenced, but can be by using a Geographical Information System (GIS). Each of the three components has 4212 pixels per row, and 3821 rows, for a total of nearly 16 megabytes in each data file. Brief documentation for each product is in separate files, for example, STCRX85.HED, and in the appendices; the geospatial metadata are contained in files *.MTA; and a TIFF copy of the images are in files *.TIF. The generic binary raster data are in files *.BIN.

Copies of this CD-ROM are no longer available from the NODC Online Store.

圣克罗伊河口区域海岸变化分析项目光盘数据集，采用1985年至1992年的陆地卫星专题制图仪（Landsat Thematic Mapper, TM）影像，对美国缅因州与加拿大境内的圣克罗伊河口及帕萨马科迪湾开展区域变化分析。本项目由美国鱼类及野生动物管理局、缅因湾项目与加拿大环境部合作实施。该光盘由美国国家海洋和大气管理局（NOAA）海岸海洋项目的河口栖息地研究项目、国家海洋渔业局、国家海洋学数据中心以及国家地球物理数据中心合作制作。

海岸开发的稳步推进伴随而来的是非点源污染、海岸侵蚀与其他环境威胁。为增进对这类变化的认知，海岸变化分析项目（Coastal Change Analysis Program, C-CAP）致力于制定一套全美通用的标准规程，用于监测美国沿海区域的土地覆盖与栖息地变化。圣克罗伊河口数据集是该系列光盘数据集的第二版。该区域历史上作为鲑鱼栖息地极具价值，如今却面临缅因州与加拿大大型林业产业活动带来的变化威胁。明晰此类变化发生的位置与方式，对制定合理的资源管理决策至关重要。

圣克罗伊河口数据集产品包含三部分：(1) 1985年土地覆盖分析结果，(2) 1992年土地覆盖分析结果，以及(3) 土地覆盖变化检测结果，全部采用二进制栅格格式存储。这些数据采用通用横轴墨卡托（Universal Transverse Mercator, UTM）坐标系，未显式进行地理配准，但可通过地理信息系统（Geographical Information System, GIS）完成配准。三个组件的每一行均包含4212个像素，共3821行，每个数据文件总大小近16兆字节。各产品的简要说明存储于单独的文件中，例如STCRX85.HED，同时也收录于附录中；地理空间元数据存储于*.MTA格式文件中；影像的TIFF副本存储于*.TIF格式文件中；通用二进制栅格数据存储于*.BIN格式文件中。

该光盘的副本已不再通过国家海洋学数据中心在线商店提供。
