North Central Coast: Aerial surveys and classification of San Rafael Intertidal Habitats, 2010

This intertidal habitat classification dataset was developed for the Sea Grant MPA Baseline Program as part of the project “High Resolution Nearshore Substrate Mapping and Persistence with Multispectral Aerial Imagery” (#R/MPA17 09-015). The study region is the California North Central Coast (NCC). This particular file shows coverage of the USGS San Rafael orthoquad region. Ocean Imaging acquired the imagery used for this analysis using the Digital Multispectral Camera (DMSC). Fugro EarthData acquired the imagery used for this project between 09/22/2010 – 09/23/2010 and delivered fully georeferenced and orthorectified, 12-bit imagery with a spatial resolution of 0.30 meters to OI in 2011. Details on these systems and the data processing are below in the Lineage section of this document. Individual DMSC and ADS40 image tiles were mosaicked into sections based on the USGS orthoquads for the California North Central Coast in order to generate the multispectral imagery required to produce the habitat classification thematic maps of the California North Central Coast’s intertidal region and kelp beds from Pigeon Point up to Point Arena, including select bays and river mouths designated as MPAs. Additional information on the classification procedures used are outlined in the Methods and Sampling section of this document. This dataset was originally uploaded to Oceanspaces (http://oceanspaces.org/) in 2013 as part of the North Central Coast baseline monitoring program. In 2022 this dataset was uploaded to the California Ocean Protection Council Data Repository by Mike Esgro ([e-mail]) and Rani Gaddam ([e-mail]). The imagery and habitat classification products have been included in the dataset as ERDAS Imagine (.img), GeoTif (.tif) and ESRI shapefile formats. Every attempt has been made to include all of the original data and metadata, submitted in 2013, but please contact the Data Set Contacts with any questions. The long-term California MPA boundary and project info tables referenced in this dataset can be found as a separate dataset here: https://opc.dataone.org/view/doi:10.25494/P64S3W.

本潮间带生境分类数据集是为海洋拨款（Sea Grant）保护区基线计划开发，作为项目“基于多光谱航空影像的近岸高分辨率底质制图与持久性分析”（High Resolution Nearshore Substrate Mapping and Persistence with Multispectral Aerial Imagery，项目编号#R/MPA17 09-015）的组成部分。研究区域为加利福尼亚中北海岸（California North Central Coast，简称NCC）。本文件覆盖美国地质调查局（United States Geological Survey，USGS）圣拉斐尔正射影像图幅区域。
本次分析所用影像由海洋成像公司（Ocean Imaging，OI）通过数字多光谱相机（Digital Multispectral Camera，DMSC）采集。富固地球数据（Fugro EarthData）于2010年9月22日至2010年9月23日采集本项目所需影像，并于2011年将经过完全地理配准与正射校正、空间分辨率为0.30米的12位影像交付给OI。有关这些采集系统与数据处理的详细信息，请参见本文档的“数据谱系（Lineage）”章节。
为生成加利福尼亚中北海岸潮间带与海带床的生境分类专题图，研究人员将单幅DMSC与ADS40影像瓦片按照美国地质调查局正射影像图幅拼接为分区块影像，覆盖范围从鸽子角（Pigeon Point）至阿雷纳角（Point Arena），包含被指定为海洋保护区（Marine Protected Area，MPA）的部分海湾与河口。本数据集所用分类流程的额外细节，请参见本文档的“方法与采样（Methods and Sampling）”章节。
本数据集最初于2013年作为中北海岸基线监测计划的一部分上传至Oceanspaces平台（http://oceanspaces.org/）。2022年，Mike Esgro（[e-mail]）与Rani Gaddam（[e-mail]）将本数据集上传至加利福尼亚海洋保护委员会数据仓库。
本数据集包含的影像与生境分类产品采用ERDAS Imagine（.img）、GeoTif（.tif）与ESRI形状文件（ESRI shapefile）格式。我们已尽可能完整保留2013年提交的原始数据与元数据，如有任何疑问，请联系数据集联系人。
