SCR_Aerial_SantaCruzIslandNorthEast_10142012_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 14, 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 Scorpion 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.

本栅格数据集为南海岸海洋保护区（Marine Protected Area, MPA）基线计划所开发，作为项目“利用历史及同期多光谱影像进行近岸底质制图与变化分析”（#R/MPA 30 10-049）的组成部分。本研究区域为南海岸区域（South Coast Region, SCR）。影像于2012年10月14日获取，空间分辨率为0.3米，采用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内的《The Microsoft Vexcel UltraCam X.pdf》文件，以及OceanSpaces.org服务器中的相关内容。本次影像镶嵌产品是将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，请参见本文档的数据谱系章节。研发团队依据覆盖的岛屿、当地沿海区域及SCR海洋保护区（MPA）分区，将单幅UCX影像瓦片拼接为若干分区，最终生成该多光谱影像产品。后续该影像被用于绘制从加利福尼亚州康塞普西翁角至帝王海滩的SCR潮间带区域与海藻床栖息地分类专题图。本次交付的影像文件采用GeoTIFF格式。本栅格影像数据集为拼接后的多光谱影像，覆盖红、绿、蓝及近红外（RGB、NIR）光谱波段，研究覆盖范围为加利福尼亚州从康塞普西翁角至帝王海滩的南加州沿海区域，目标对象为该区域的巨藻床与潮间带。本栅格数据集包含蝎子州立海洋保护区（State Marine Reserve, SMR）范围数据。2013年，作为南海岸基线监测计划的一部分，本数据集最初上传至Oceanspaces平台（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州海洋保护委员会数据仓储库（https://opc.dataone.org/），并于同期向数据集补充了GIS分析产品。有关加利福尼亚州长期海洋保护区（MPA）边界与项目信息表的独立数据集，可通过以下链接获取：https://opc.dataone.org/view/doi:10.25494/P64S3W。
