    • NOAA Integrated Ocean and Coastal Mapping (IOCM) orthorectified mosaic image tiles, Merrimack River and Plum Island Sound, Massachusetts, June 2011 (NCEI Accession 0103944)

    Metadata Updated: March 17, 2023

    This dataset contains both true color (RGB) and infrared (IR) ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative for the Merrimack River - Plum Island Sound region of Massachusetts. The source imagery was acquired on 20110619. The 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.

    Data for this region are in two subdirectories, which hold RGB and IR imagery for both mean high water (MHW) and mean lower low water (MLLW) periods. (MLLW, i.e., the average of the lower low water height of each tidal day observed over the National Tidal Datum Epoch. For stations with shorter series, comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the National Tidal Datum Epoch).

    Imagery is in TIFF format with associated browse graphic (JPEG), .omd, .his, and metadata files in Federal Geographic Data Committee (FGDC) format.

    The ground sample distance (GSD) for each pixel is 0.50 m.
