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 December 09, 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 Naples SMCA and Campus Point SMCA.

本栅格与矢量数据集为美国海洋赠款（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线计划开发，隶属于项目“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）。本研究覆盖区域为南海岸区域（SCR）。影像采集于2012年12月9日，空间分辨率为0.3米，采用微软UltraCam-X数码相机采集红、绿、蓝及近红外波段数据。有关UltraCam-X相机系统及各波段波长的详细信息，可查阅影像数据交付介质及OceanSpaces.org服务器的Support文件夹内的"The Microsoft Vexcel UltraCam X.pdf"文件。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）的成果。有关该系统及数据处理的详细说明，请参见本文档的溯源章节。为生成本多光谱影像产品，研究人员根据覆盖的岛屿、当地沿海区域以及SCR海洋保护区范围，将单张UCX影像瓦片拼接为若干分区。后续利用该影像生成了覆盖从加州康塞普西翁角至帝国海滩的SCR海域海带床生境分类专题图。交付的影像文件采用地理标记图像文件格式（GeoTIFF）。有关解译地物类别及处理方法的更多信息，请参见本文档的溯源章节。本栅格数据集包含加州南海岸区域（SCR）从康塞普西翁角至帝国海滩的近岸巨藻床生境分类数据。本次特定的栅格分类数据涵盖那不勒斯SMCA及校园点SMCA。
