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.

本栅格数据集系为海岸资助南海岸海洋保护区基线计划开发，作为项目“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）的组成部分。研究区域为南海岸区域（South Coast Region，SCR）。影像采集于2012年10月15日，空间分辨率达0.3米，由微软（Microsoft）UltraCam-X数码相机采集红、绿、蓝与近红外波段的影像数据。关于UltraCam-X相机系统与各波段波长的相关信息，可在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服务器中查阅。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）的成果，该系统与数据处理的详细信息见本文档的数据谱系（Lineage）章节。原始UltraCam-X影像瓦片依据所覆盖的岛屿、当地沿海区域及SCR海洋保护区（Marine Protected Area，MPA）分区进行镶嵌，进而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从康塞普西翁角（Point Conception）至帝王海滩（Imperial Beach）的南海岸区域潮间带与海带床生境分类专题地图。本次交付的影像文件采用GeoTIFF格式。本栅格影像数据集为经镶嵌的多光谱影像，涵盖红、绿、蓝与近红外（RGB、NIR）光谱波段，研究目标覆盖加利福尼亚州从康塞普西翁角至帝王海滩的南加州海岸带巨型海带床与潮间带区域。本栅格数据集包含长点海洋保护区（Long Point SMR）、蓝洞海洋保护区（Blue Cavern SMCA）以及箭头角至狮头角海洋保护区（Arrow Point to Lion Head Point SMCA）。
