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 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 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 ALong Point SMR, Blue Cavern SMCA and Arrow point to Lion Head Point SMCA.本栅格与矢量数据集为海洋推广计划（Sea Grant）南海岸海洋保护区基线项目开发，属于“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”（#R/MPA 30 10-049）项目的组成部分。本研究覆盖区域为南海岸区域（South Coast Region，简称SCR）。影像采集于2012年10月14日，空间分辨率0.3米，采用微软UltraCam-X数码相机获取红、绿、蓝及近红外波段数据。关于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《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2米地面采样距离（GSD）后的成果。本系统及数据处理的详细说明见本文档的数据溯源（Lineage）章节。为生成该多光谱影像产品，研究人员根据覆盖的岛屿、当地沿海区域及SCR海洋保护区分区，将单张UltraCam-X（UCX）影像瓦片拼接为若干分区。后续利用该影像生成了从加利福尼亚州康塞普西翁角到帝国海滩的SCR海带床生境分类专题图。交付的影像文件采用GeoTIFF格式。关于分类体系及处理方法的更多细节，同样见于本文档的数据溯源章节。本栅格数据集包含加利福尼亚州南海岸区域（SCR）从康塞普西翁点至帝国海滩的近海巨藻床生境分类数据。本次特定的栅格分类数据涵盖了阿朗角海洋保护区（ALong Point SMR）、蓝洞海洋保护区（Blue Cavern SMCA）以及从箭头角到狮头角的海洋保护区（Arrow Point to Lion Head Point SMCA）。
