NOAA Integrated Ocean and Coastal Mapping (IOCM) true color (RGB) orthorectified mosaic image tiles, Baton Rouge to LaPlace, Louisiana 2010 (NODC Accession 0074374)

This data set contains ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative of the Mississippi River (Baton Rouge to LaPlace, the Louisiana shoreline, the Lake Charles area, and LaPlace to Venice). The true color images were acquired with an Applanix Digital Sensor System (DSS). The original images were acquired at a higher resolution than the final ortho-rectified mosaic. Ortho-rectified mosaic tiles are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data.

For the Louisiana shoreline, the purpose of the imagery was to provide digital shoreline and orthophotos for NOAA nautical charts. The shoreline area covers the Barrier Islands of Terrebonne and Timbalier Bays on the coast of the State of Louisiana.

For Baton Rouge, source imagery was acquired on March 13, 2010, March 14, 2010 and March 15, 2010. The ground sample distance (GSD) for each pixel is 0.5 m. These data are in .his, .tif, and .jpg formats with associated metadata. Additional orthoimagery for this region (Baton Rouge to Southwest Pass) are filed under NODC accession numbers 0103945 and 0104414. Additional ortho-mosaic data is available at the NODC under individual accession numbers.

Ortho-rectified mosaic tiles are not intended for mapping, charting or navigation.

本数据集包含经正射校正的镶嵌瓦片，该产品由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）综合海洋与海岸测绘（Integrated Ocean and Coastal Mapping, IOCM）项目针对密西西比河（巴吞鲁日至拉普拉斯段、路易斯安那州岸线、查尔斯湖区域以及拉普拉斯至威尼斯段）生成。本数据集的真彩色影像采用Applanix数字传感器系统（Digital Sensor System, DSS）采集，原始影像的分辨率高于最终生成的正射校正镶嵌影像。正射校正镶嵌瓦片是NOAA海岸测绘项目（Coastal Mapping Program, CMP）的配套衍生产品，由更广泛的综合海洋与海岸测绘项目开发，旨在提升该数据的多用途支撑能力。

针对路易斯安那州岸线区域，该影像的用途是为NOAA海图提供数字岸线数据与正射影像产品。该岸线区域覆盖路易斯安那州沿岸特雷邦湾（Terrebonne Bay）与廷巴利耶湾（Timbalier Bay）的障壁岛。

巴吞鲁日区域的源影像采集于2010年3月13日、2010年3月14日及2010年3月15日。每个像素的地面采样距离（Ground Sample Distance, GSD）为0.5米。此类数据包含.his、.tif及.jpg三种格式，并附带关联元数据。该区域（巴吞鲁日至西南航道）的额外正射影像已按国家海洋数据中心（National Oceanographic Data Center, NODC）入库编号0103945和0104414归档。其他正射镶嵌数据可在国家海洋数据中心通过单独入库编号获取。

正射校正镶嵌瓦片不适用于测绘、海图绘制或导航用途。
