Little Vermilion Bay Sediment Trapping TV-12 2009 Land-Water Data

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 land-water classification for the Little Vermilion Bay Sediment Trapping for the year 2009. The land-water data were derived from interpretation of color infrared photography flown at 1:12000. All areas characterized by emergent vegetation, wetland forest, scrub-shrub, or uplands are classified as land, while open water, aquatics, and mud flats were classified as water.

路易斯安那州立法机构制定了《海岸湿地规划、保护与修复法案》（Coastal Wetlands Planning, Protection and Restoration Act，CWPPRA），旨在保护、修复、创建并改善路易斯安那州的海岸湿地生态。依据该法案编制的修复计划明确要求，需对每一项海岸湿地修复项目在长期遏制海岸湿地流失方面的实施成效进行评估。本数据集包含2009年度小弗米利恩湾沉积物截留项目的湿地水陆分类数字数据，该数据源自对1:12000比例尺彩色红外航空摄影照片的解译分析。其中，所有覆盖挺水植被、湿地森林、灌丛或高地的区域均被归类为陆地，而开阔水域、水生植被及潮滩则被归类为水体。
