2008 NOAA NGS MHW Near-Infrared Mosaic of Portsmouth, NH
Integrated Ocean and Coastal Mapping Product (IOCM). The images were acquired from a nominal altitude of 7,500 feet above ground level (AGL), using an Applanix Digital Sensor System (DSS). Imagery products are true color (RGB) and infrared (IR) images. Images have been orthorectified and mosaiced to produce a seamless data set. For information about combining the IR image and the RGB image into a 4 band NIR image, please download the IOCM Band Stack Guide document at this link: ftp://coast.noaa.gov/temp/metadata_supp
