These raster and vector dataset 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). Imagery was acquired on October 15, 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 2 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 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 along the California South Coast Region (SCR) from from Point Conception, CA down to Imperial beach, CA. This specific raster classification includes the Lover's Cove SMCA and Casino Point 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.

本栅格数据集与矢量数据集是为海洋赠款计划（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，作为项目“基于历史与同期多光谱影像的近岸底质制图与变化分析”（编号#R/MPA 30 10-049）的组成部分。本研究的研究区域为南海岸区域（South Coast Region，简称SCR）。
影像采集于2012年10月15日，空间分辨率为0.3米，采用微软UltraCam-X数码相机（Microsoft UltraCam-X）采集红、绿、蓝及近红外波段的影像数据。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及OceanSpaces.org服务器的Support文件夹内的《Microsoft Vexcel UltraCam X.pdf》文件中查阅。
本影像镶嵌产品是将0.3米分辨率数据重采样至2米地面采样距离（Ground Sample Distance, GSD）后的成果。该相机系统与数据处理的详细说明详见本文档的谱系（Lineage）章节。为生成该多光谱影像产品，所有UCX影像分幅均依据所覆盖的岛屿、当地沿海区域及SCR海洋保护区分区进行镶嵌拼接。
后续利用该批影像制作了覆盖加利福尼亚州康塞普西翁角（Point Conception）至帝国海滩（Imperial Beach）的SCR海域海带床生境分类专题图。本次交付的影像文件采用GeoTIFF格式。有关分类体系与处理方法的详细信息详见本文档的谱系章节。
本栅格数据集包含加利福尼亚州南海岸区域（SCR）从康塞普西翁角至帝国海滩的近岸巨藻床生境分类结果。本次栅格分类结果涵盖洛夫斯湾州立海洋保护区（State Marine Conservation Area, SMCA）与卡西诺角州立海洋保护区（Casino Point 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，Mike Esgro（邮箱：[e-mail]）与Rani Gaddam（邮箱：[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库（https://opc.dataone.org/），并于同期将地理信息系统（Geographic Information System, GIS）分析产品添加至本数据集。
