The images were acquired from a nominal altitude of 5,000 feet above ground level (AGL), using an Applanix Digital Sensor System (DSS). Imagery products are true color (RGB) and infrared (IR) images. The IR images were acquired with a 850 nm cut on filter. Images have been orthorectified and mosaiced to produce a seamless data set. This imagery was acquired by the NOAA Remote Sensing Division to support NOAA's IOCM requirements. It is not intended for mapping, charting or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne digital imagery. Clouds may be present in the imagery. Mosaic data have not been histogram stretched and only minimal color balancing has been performed. The ground sample distance (GSD) for each pixel is 0.5 m.2008年新罕布什尔州美国国家海洋和大气管理局（NOAA）航空摄影影像分幅下载链接：综合海洋与海岸测绘（IOCM）产品。本数据集隶属于综合海洋与海岸测绘（Integrated Ocean and Coastal Mapping, IOCM）产品体系。影像采集于标称地面以上高度5000英尺（AGL），采用Applanix数字传感器系统（DSS）完成采集。本数据集包含真彩色（RGB）与红外（IR）两类影像产品，其中红外影像采用850nm截止滤光片采集。所有影像均经过正射校正与镶嵌拼接处理，生成无缝数据集。该套影像由NOAA遥感分部采集，旨在满足NOAA的IOCM业务需求，不可用于测绘、海图编制或导航作业。此外，本数据集还将用于持续开展的机载数字影像标准测试与开发研究。影像中可能存在云覆盖区域。镶嵌拼接后的影像数据未进行直方图拉伸处理，仅执行了极少量的色彩平衡操作。每个像素对应的地面采样距离（GSD）为0.5米。
