SCR_Aerial_SantaBarbaraIsland_06072012_IntClass

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 June 7, 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 Santa Barbara Island SMR. 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.

本栅格数据集是为海洋赠地南海岸海洋保护区（Marine Protected Area，简称MPA）基线计划开发，作为“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”（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，简称SCR）。
影像采集于2012年6月7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，简称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“数据谱系（Lineage）”章节。
各UltraCam-X（UCX）影像瓦片将依据覆盖的岛屿、当地沿海区域及SCR 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潮间带及海藻床生境分类专题图。
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，请参见本文档的数据谱系章节。
本栅格数据集包含从加利福尼亚州康塞普西翁点至帝国海滩的南海岸区域（SCR）沿岸近海巨型海藻床及/或潮间带生境分类数据。本次栅格分类覆盖圣巴巴拉岛海洋州立保护区（Santa Barbara Island SMR）。
本数据集最初于2013年作为南海岸基线监测计划的一部分，上传至Oceanspaces平台（http://oceanspaces.org/）及生物复杂性知识网络（Knowledge Network for Biocomplexity，简称KNB，https://knb.ecoinformatics.org/data）。2022年，由Mike Esgro（[e-mail]）与Rani Gaddam（[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库（https://opc.dataone.org/），同期为数据集新增了GIS分析产品。长期加利福尼亚MPA边界及项目信息表可通过以下链接的独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
