This raster dataset was developed for the Sea Grant South Coast MPA Baseline Program as part of the project “Nearshore Substrate Mapping and Change Analysis using This raster dataset was 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). Imagery was acquired on October 14, 2012 at a spatial resolution of 0.3 meters using a Microsoft UltraCam-X digital camera acquiring in the red, green, blue and near-infrared bands. Information on the UltraCam-X camera system and wavelengths for each ban can be found in the file "The Microsoft Vexcel UltraCam X.pdf" included in the Support folder on the image data delivery media and on the OceanSpaces.org server. This image mosaic product is a result of the resampling of the 0.3 meter data to 1 meter GSD. Details on this system and the data processing are below in the Lineage section of this document. Individual UCX 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 intertidal region and kelp beds from Point Conception to Imperial Beach, CA. The imagery files deliverd are in GeoTIFF format. More information on the classes resolved and processing methods are in the Lineage section of this document. This raster dataset contains a habitat classification of either offshore giant kelp beds and/or the intertidal zone along the California South Coast Region (SCR) from from Point Conception, CA down to Imperial beach, CA. This specific raster classification includes the Painted Cove 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.

本栅格数据集是为海洋资助计划（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，作为“利用历史与同期多光谱影像开展近岸底质制图与变化分析”（项目编号：#R/MPA 30 10-049）研究项目的一部分。本研究的覆盖区域为南海岸区域（South Coast Region, SCR）。影像采集于2012年10月14日，空间分辨率为0.3米，采用微软UltraCam-X数码相机完成红、绿、蓝及近红外波段的影像采集。有关UltraCam-X相机系统及各波段波长的详细信息，可在影像数据交付介质支持文件夹内的"The Microsoft Vexcel UltraCam X.pdf"文件，以及OceanSpaces.org服务器中查阅。本影像镶嵌产品是将0.3米分辨率数据重采样至1米地面采样距离（Ground Sample Distance, GSD）的成果。有关该相机系统与数据处理的详细说明，详见本文档的“数据溯源（Lineage）”章节。各UltraCam-X影像瓦片依据覆盖的岛屿、当地沿海区域以及南海岸区域海洋保护区分区进行镶嵌拼接，最终生成本多光谱影像产品。后续利用该影像制作了从加利福尼亚州康塞普西翁角到帝国海滩的南海岸区域潮间带与海藻床生境分类专题地图。交付的影像文件采用GeoTIFF格式。有关解译分类类别与处理方法的更多细节，详见本文档的数据溯源章节。本栅格数据集包含从加利福尼亚州康塞普西翁角至帝国海滩的加州南海岸区域近海巨型海藻床及/或潮间带的生境分类数据。本栅格分类数据涵盖了彩绘湾海洋保护区（State Marine Conservation Area, SMCA）。本数据集最初于2013年作为南海岸基线监测项目的一部分，上传至Oceanspaces平台（http://oceanspaces.org/）与生物复杂性知识网络（Knowledge Network for Biocomplexity, KNB, https://knb.ecoinformatics.org/data）。2022年，由Mike Esgro（[e-mail]）与Rani Gaddam（[e-mail]）将本数据集迁移至加州海洋保护委员会数据仓储（https://opc.dataone.org/）。同期，本数据集新增了GIS分析成果。加州长期海洋保护区边界与项目信息表格可通过以下链接的独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
