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.

本栅格数据集由海洋赠款（Sea Grant）南海岸海洋保护区（Marine Protected Area, MPA）基线计划开发，作为项目“基于历史与同期多光谱影像的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）。
该影像采集于2012年10月14日，空间分辨率为0.3米，采用微软UltraCam-X数码相机（Microsoft UltraCam-X）进行采集，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，可在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服务器中查阅。
本影像镶嵌产品是将0.3米分辨率数据重采样至1米地面采样距离（Ground Sampling Distance, GSD）后的成果。本系统及数据处理的详细说明详见本文档的谱系章节。
为生成该多光谱影像产品，研究人员根据覆盖的岛屿、当地沿海区域及SCR海洋保护区区域，将各UCX影像分幅镶嵌为若干分区。后续该影像被用于绘制从加利福尼亚州孔塞普申角至帝国海滩的SCR潮间带及海藻床生境分类专题图。
交付的影像文件采用GeoTIFF格式。本栅格影像数据集为镶嵌后的多光谱影像，覆盖红、绿、蓝及近红外（RGB、NIR）光谱波段，研究目标为加利福尼亚州孔塞普申角至帝国海滩沿线的南加州海岸巨型海藻床及潮间带区域。本栅格数据集涵盖蝎子海洋保护区（Scorpion SMR）。
