SCR_Aerial_SantaCatalinaIslandNorth_10052012_Imagery

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 15, 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. This raster image dataset represents mosaicked, multi-spectral imagery in the red, green, blue and near-infrared (RGB,NIR) spectral bands, targeting giant kelp beds and the intertidal zone along the Southern California Coast region from Point Conception, CA down to Imperial beach, CA. This raster dataset includes the Long Point SMR, Blue Cavern SMCA, and the Arrow Point to Lion Head 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.

本栅格数据集为海洋资助局（Sea Grant）南海岸海洋保护区（Marine Protected Area，MPA）基线项目开发，是项目"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"（编号#R/MPA 30 10-049）的成果之一。研究区域为南海岸区域（South Coast Region，SCR）。影像于2012年10月15日采集，空间分辨率0.3米，采用微软UltraCam-X数码相机获取红、绿、蓝及近红外波段数据。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《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。关于该系统及数据处理的详细说明见本文档"数据谱系"（Lineage）章节。原始UCX影像瓦片依据覆盖的岛屿、沿海区域及SCR MPA区划进行镶嵌，以生成该多光谱影像产品。后续利用该影像完成了从加利福尼亚州孔塞普申角（Point Conception）至帝国海滩（Imperial Beach）的SCR潮间带及巨藻床生境分类专题图制作。本次交付的影像文件采用GeoTIFF格式。
本栅格影像数据集为镶嵌后的多光谱影像，包含红、绿、蓝及近红外（RGB、NIR）光谱波段，针对加利福尼亚州南部沿海孔塞普申角至帝国海滩区域的巨藻床与潮间带开展采集。本栅格数据集涵盖长点州立海洋生物保护区（Long Point SMR）、蓝洞州立海洋保护区（Blue Cavern SMCA）以及箭点至狮头点州立海洋保护区（Arrow Point to Lion Head Point 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平台（http://oceanspaces.org/）及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/），并同期添加了地理信息系统（GIS）分析产品。加州长期MPA边界及项目信息表格可通过以下链接获取为独立数据集：https://opc.dataone.org/view/doi:10.25494/P64S3W。
