SCR_Aerial_CoalOilPoint_12092012_KelpClass

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. 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.本栅格与矢量数据集是为海洋资助计划（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，作为“利用历史与同期多光谱影像开展近岸底质制图及变化分析”（项目编号：#R/MPA 30 10-049）的组成部分。研究区域为南海岸区域（South Coast Region, SCR）。影像于2012年12月9日采集，空间分辨率为0.3米，采用微软UltraCam-X数码相机完成红、绿、蓝及近红外四个波段的影像数据采集。关于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2米地面采样距离（Ground Sample Distance, GSD）的成果，该系统及数据处理的详细说明见本文档“谱系（Lineage）”章节。原始UCX影像瓦片根据覆盖的岛屿、沿海局部区域及SCR海洋保护区分区进行镶嵌，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孔塞普申角到帝国海滩的SCR海带床生境分类专题图。交付的影像文件采用GeoTIFF格式，关于分类体系与处理方法的更多信息，详见本文档的谱系章节。本栅格数据集包含加利福尼亚南海岸区域（SCR）从孔塞普申角到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州立海洋保护区（State Marine Conservation Area, SMCA）与校园点州立海洋保护区（State Marine Conservation Area, SMCA）。本数据集最初于2013年作为南海岸基线监测项目的一部分上传至Oceanspaces（http://oceanspaces.org/）与生物复杂性知识网络（Knowledge Network for Biocomplexity, KNB, https://knb.ecoinformatics.org/data）。2022年，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/），并同期将GIS分析产品添加至数据集。长期加州MPA边界与项目信息表格可通过以下独立数据集获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
