SCR_Aerial_PointDume_06252012_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 June 25, 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 Point Dume SMCA and the Point Dume SMR.

本栅格数据集为美国海洋资助计划（Sea Grant）南海岸海洋保护区（Marine Protected Area，MPA）基线项目开发，系“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”（项目编号#R/MPA 30 10-049）项目的组成部分。研究区域为南海岸区域（South Coast Region，SCR）。该影像于2012年6月25日采用微软（Microsoft）UltraCam-X数码相机采集，空间分辨率为0.3米，覆盖红、绿、蓝及近红外四个波段。有关UltraCam-X相机系统及各波段波长的详细信息，可于影像数据交付介质的支持文件夹内的"The Microsoft Vexcel UltraCam X.pdf"文件，以及OceanSpaces.org服务器中查询。本影像镶嵌产品系将0.3米分辨率数据重采样至1米地面采样距离（Ground Sample Distance，GSD）后的最终产物。该系统及数据处理的详细说明见本文档的“谱系（Lineage）”章节。原始UCX影像瓦片依据覆盖岛屿、当地沿海区域及SCR海洋保护区分区进行镶嵌，最终生成本多光谱影像产品。后续利用该影像生成了加利福尼亚州康塞普西翁角至帝国海滩范围内的SCR潮间带与巨藻床生境分类专题图。本次交付的影像文件均采用GeoTIFF格式存储。本栅格影像数据集为镶嵌完成的多光谱影像，涵盖红、绿、蓝及近红外（RGB、NIR）光谱波段，覆盖加利福尼亚州南海岸区域，北起康塞普西翁角、南至帝国海滩，主要针对该区域的巨藻床与潮间带进行采集。本栅格数据集包含杜梅角州立海洋保护管理区（SMCA）与杜梅角州立海洋保护区（SMR）。
