These raster and vector datasets were developed for the Sea Grant South Coast MPA Baseline Program as part of the project “Nearshore Substrate Mapping and Change Analysis using Historical and Concurrent Multispectral Imagery” (#R/MPA 30 10-049). The study region is the South Coast Region (SCR). Ocean Imaging acquired this imagery on 12/07/2011 using the Digital Multispectral Camera (DMSC). Details on this system and the data processing are below in the Lineage section of this document. Details on this system and the data processing are below in the Lineage section of this document. Individual DMSC image tiles were mosaicked into sections based on the islands covered and local coastal regions as well as the SCR MPA zones in order to generate this multispectral image product. These imagery were subsequently used to generate habitat classification thematic maps of the SCR's kelp beds from Point Conception to Imperial Beach, CA. The imagery files deliverd are in GeoTIFF format.This raster dataset contains a habitat classification of either offshore giant kelp beds along the California South Coast Region (SCR) from from Point Conception, CA down to Imperial beach, CA. This specific raster classification includes the Long Point SMR, Blue Cavern SMCA and Arrow Point to Lion Head SMCA.This dataset was originally uploaded to Oceanspaces (http://oceanspaces.org/) and the Knowledge Network for Biocomplexity (KNB, https://knb.ecoinformatics.org/data) in 2013 as part of the South Coast baseline monitoring program. In 2022 this dataset was moved to the California Ocean Protection Council Data Repository (https://opc.dataone.org/) by Mike Esgro ([e-mail]) and Rani Gaddam ([e-mail]). At that time the GIS analysis products were added to the dataset.The long-term California MPA boundary and project info tables can be found as a separate dataset here: https://opc.dataone.org/view/doi:10.25494/P64S3W.

本栅格与矢量数据集由海洋赠地计划（Sea Grant）南海岸海洋保护区（Marine Protected Area，简称MPA）基线项目研发，隶属于项目"基于历史与同期多光谱影像的近岸底质制图与变化分析"（项目编号：#R/MPA 30 10-049）。本研究区域为南海岸区域（South Coast Region，简称SCR）。Ocean Imaging公司于2011年12月7日采用数字多光谱相机（Digital Multispectral Camera，简称DMSC）完成本次影像采集。有关该采集系统与数据处理流程的详细说明，请参见本文档的数据溯源章节。为生成本多光谱影像产品，研发团队依据覆盖的岛屿、沿岸区域及SCR MPA分区，对单张DMSC影像瓦片进行镶嵌拼接，形成分区影像成果。后续基于该影像数据，研发人员为加利福尼亚州康塞普西翁角至帝国海滩范围内的SCR海带床生成了生境分类专题地图。本次交付的影像文件采用GeoTIFF格式。本栅格数据集涵盖加利福尼亚州南海岸区域（SCR）从康塞普西翁点到帝国海滩的近岸巨藻床生境分类数据，本次栅格分类数据包含长点州立海洋保护区（Long Point SMR）、蓝洞州立海洋保护保育区（Blue Cavern SMCA）以及箭点至狮头海洋保护保育区（Arrow Point to Lion Head SMCA）。本数据集最初于2013年作为南海岸基线监测项目的组成部分，上传至Oceanspaces平台（http://oceanspaces.org/）与生物复杂性知识网络（Knowledge Network for Biocomplexity，简称KNB，https://knb.ecoinformatics.org/data）。2022年，Mike Esgro（[e-mail]）与Rani Gaddam（[e-mail]）将本数据集迁移至加利福尼亚海洋保护委员会数据仓储平台（https://opc.dataone.org/），并于同期将地理信息系统（Geographic Information System，简称GIS）分析产品纳入本数据集。长期加州MPA边界与项目信息表格可通过以下链接获取独立数据集：https://opc.dataone.org/view/doi:10.25494/P64S3W。
