SCR_Aerial_Matlahuayl_SMR_2002_2012_IntertidalChange

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 in 2002 using the OI DMSC MKII multispectral instrument and in 2012 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. The goal of this analysis was to characterize and analyze the decadal-long change in several sub/intertidal, general substrate/vegetation classes. The classes were identified in habitat classifications created as part of 2001-2002 work completed for the San Diego Association of Governments (SANDAG), and compared to the same classes identified and mapped during 2012 as part of this project. 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 change detection analysis of the intertidal zone along the California South Coast Region (SCR) from from Dana Point, CA down to Imperial beach, CA. This specific dataset covers the Matlahuayl 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资助计划（Sea Grant）下属的南海岸海洋保护区（Marine Protected Area, MPA）基线项目开发，作为项目“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”（编号#R/MPA 30 10-049）的组成部分。本研究的区域为南海岸区域（South Coast Region, SCR）。影像数据分别于2002年采用OI DMSC MKII多光谱仪器采集，及2012年使用Microsoft UltraCam-X数码相机采集，该相机的波段覆盖红、绿、蓝及近红外波段。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，以及OceanSpaces.org服务器上的《The Microsoft Vexcel UltraCam X.pdf》文件。本分析的核心目标为表征并剖析多个潮下带、潮间带及通用底质/植被类别的十年尺度变化。上述类别源自2001-2002年为圣迭戈政府联合会（San Diego Association of Governments, SANDAG）完成的栖息地分类工作，本项目将其与2012年期间识别并制图的同类别进行对比分析。本次交付的影像文件采用GeoTIFF格式。有关所解析类别及处理方法的更多细节，可参见本文档的“谱系（Lineage）”章节。本栅格数据集包含了加利福尼亚州南海岸区域（SCR）从加州达纳点至帝国海滩的潮间带区域变化检测分析成果，本特定数据集覆盖Matlahuayl海洋保护区（State Marine Reserve, SMR）。本数据集最初于2013年作为南海岸基线监测项目的组成部分，上传至Oceanspaces（http://oceanspaces.org/）及生物多样性知识网络（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/），并于同期将地理信息系统（Geographic Information System, GIS）分析产品添加至本数据集。可通过以下链接获取包含长期加州海洋保护区边界及项目信息表格的独立数据集：https://opc.dataone.org/view/doi:10.25494/P64S3W。
