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 16, 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 Carrington Point SMR and Skunk Point SMR.

本栅格与矢量数据集为海洋资助计划（Sea Grant）南海岸海洋保护区基线项目开发，系课题“基于历史与同步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）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16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，可参阅影像数据交付介质支持文件夹及OceanSpaces.org服务器中的《The Microsoft Vexcel UltraCam X.pdf》文件。

本影像镶嵌产品系将0.3米分辨率数据重采样至2米地面采样距离（Ground Sample Distance，简称GSD）后的成果。本系统与数据处理的详细说明，请参阅本文档的数据溯源（Lineage）章节。

单张UCX影像瓦片根据其所覆盖的岛屿、当地沿海区域及SCR海洋保护区（Marine Protected Area，简称MPA）分区进行镶嵌，以生成本多光谱影像产品。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海域海带床生境分类专题图。所交付的影像文件采用GeoTIFF格式。有关分类体系与处理方法的更多细节，请参阅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）从康塞普西翁角至帝国海滩的近海巨藻床生境分类数据。本特定栅格分类数据集涵盖了卡林顿角州立海洋保护区（Carrington Point SMR）与斯康克角州立海洋保护区（Skunk Point SMR）的相关数据。
