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 05, 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 Long Point SMR, Blue Cavern SMCA, and the Arrow Point to Lion Head Point SMCA.

本栅格数据集为海洋资助计划（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，系“利用历史及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）项目的组成部分。研究区域为南海岸区域（South Coast Region, SCR）。
影像采集于2012年10月5日，空间分辨率为0.3米，采用微软UltraCam-X（Microsoft 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支持文件夹及OceanSpaces.org服务器中附带的《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1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，请见本文档的谱系（Lineage）章节。
本次采集的单张UCX（UltraCam-X）影像瓦片依据覆盖的岛屿、当地沿海区域以及SCR的MPA分区进行镶嵌，以生成该多光谱影像产品。后续利用该影像生成了从加利福尼亚州康塞普西翁角至帝王海滩的SCR潮间带及海带床生境分类专题图。
交付的影像文件采用GeoTIFF格式。有关解译地物类别及处理方法的更多信息，请见本文档的谱系章节。
本栅格数据集包含了从加利福尼亚州康塞普西翁角至帝王海滩的南海岸区域（SCR）近海巨型海带床及/或潮间带的生境分类数据。本次特定的栅格分类数据涵盖了长点SMR（Long Point SMR）、蓝洞SMCA（Blue Cavern SMCA）以及箭点至狮头角SMCA（Arrow Point to Lion Head Point SMCA）。
