Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2016, 2018, and 2021 Site 3617 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of six land-water products (2005, 2008, 2012, 2016, 2018, and 2021). The resulting matrix has 64 possible classes defined by the combination of land and water categories on those six dates.

美国路易斯安那州由《海岸湿地规划、保护与修复法案》（Coastal Wetlands Planning, Protection and Restoration Act，缩写CWPPRA）推进的湿地修复工程，需通过监测工作判定此类项目的实施成效。全海岸参考监测系统（Coastwide Reference Monitoring System，缩写CRMS）正是为支撑该多参考点监测方法而开发，该方法融合了水文地貌功能评估与概率抽样技术以开展监测工作。CRMS项目共包含约390个监测点位，覆盖各层级的水文与生态条件范围。作为CRMS的组成部分，科研人员约每三年会利用数字正射影像四分之一幅图（Digital Orthophoto Quarter Quadrangles，缩写DOQQs），在所有CRMS点位生成土地与水体分类数据。本数据集包含6份陆-水分类产品的矩阵数据，对应年份分别为2005、2008、2012、2016、2018与2021年。该矩阵共包含64种可区分的分类类别，由上述6个时间节点的土地与水体类别组合定义得到。
