Whiskey Island Caillou Lake Headlands restoration area 2016?2019 shorelines, Louisiana Barrier Island Comprehensive Monitoring Program

This data package includes a high-water shoreline position map and a structures map for each year from 2016?2019 for the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish using material dredged from Ship Shoal. For more information on this restoration project, see the project page on Louisiana Coastal Protection and Restoration Authority?s (CPRA) Coastal Information Management System (http://cims.coastal.la.gov/outreach/projects/ProjectView?projID=TE-0100). Together with previous shoreline products developed for CPRA's Barrier Island Comprehensive Monitoring (BICM) Program Phase 2, this suite of Whiskey Island shoreline position maps spans the time period before, during, and after the restoration project was conducted. The shorelines were delineated primarily using linework from existing habitat classifications of Whiskey Island. Please see the Processing Steps sections of the individual metadata files for information on methodology for map development. The BICM Program, for which these maps were developed, uses both historical data and contemporary data collections to assess and monitor changes to barrier islands, and develops data products, including shoreline position maps. For more information about the BICM Program, see Kindinger and others (2013).

本数据包涵盖了2016年至2019年期间，针对自然资源损害评估（Natural Resource Damage Assessment, NRDA）凯尤湖岬角（Caillou Lake Headlands）项目区（编号TE-0100，又称威士忌岛）的逐年高水位岸线位置图与地物结构图。本项目通过疏浚自希普浅滩（Ship Shoal）的物料，在特雷邦堂区的威士忌岛营造了170英亩的沼泽栖息地与917英亩的沙丘及海滩栖息地。如需了解该修复项目的更多详情，请访问路易斯安那州海岸保护与恢复管理局（Louisiana Coastal Protection and Restoration Authority, CPRA）海岸信息管理系统（Coastal Information Management System, CIMS）的项目页面：http://cims.coastal.la.gov/outreach/projects/ProjectView?projID=TE-0100。结合CPRA障壁岛综合监测（Barrier Island Comprehensive Monitoring, BICM）计划第二阶段此前生成的岸线产品，本套威士忌岛岸线位置图覆盖了该修复项目实施前、实施期间及实施后的完整时段。本次岸线的勾绘主要基于威士忌岛现有栖息地分类的矢量线划数据。如需了解制图方法的详细信息，请查阅各元数据文件中的“处理步骤”章节。本套岸线图所依托的BICM计划，通过整合历史数据与当代采集数据，对障壁岛的变化进行评估与监测，并生成包括岸线位置图在内的各类数据产品。如需了解BICM计划的更多内容，请参阅Kindinger等人（2013）的相关文献。
