Brady Canal Hydrologic Restoration TE-28 2008 Habitat Data Conservation Treatment Unit (CTU 1)

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create, and enhance Louisiana's coastal wetlands. The restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetland restoration project in achieving long-term solutions to arresting coastal wetland loss. This data set consists of digital data describing wetland and upland habitats for the Brady Canal for the year 2008. The habitat data were derived from interpretation of color infrared photography flown at 1:12000. Wetlands were classified according to the Cowardin, et al., classification scheme, to the level of salinity modifiers. Uplands were classified according to the Anderson, et al., classification scheme. The interpreted habitat data were then scanned, and on-screen clean up was conducted to ensure quality of the digital data.

路易斯安那州议会制定了《沿海湿地规划、保护与修复法案》（Coastal Wetlands Planning, Protection and Restoration Act，缩写CWPPRA），旨在保护、修复、营造并改善路易斯安那州的沿海湿地。依据该法案制定的修复计划明确要求，对每一项沿海湿地修复项目的有效性开展评估，以验证其能否通过长效方案遏制沿海湿地流失。本数据集包含2008年布雷迪运河（Brady Canal）的湿地与陆地生境数字数据。该生境数据源自比例尺为1:12000的彩色红外航空摄影解译成果。其中，湿地按照考瓦尔丁等人（Cowardin, et al.）的分类体系进行分类，细分至盐度修饰符层级；陆地则按照安德森等人（Anderson, et al.）的分类体系完成分类。随后，研究人员对解译得到的生境数据进行扫描，并开展屏幕清绘操作以保障数字数据的质量。
