2018 USACE NCMP Phase One Natural Color 8 Bit Imagery: Lake Ontario, NY

The mosaic image contained in this file is comprised of multiple Natural Color (RGB) images that were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system along the shoreline of Lake Ontario, New York. CZMIL integrates a lidar sensor with topographic and bathymetric capabilities, a Phase One iXU1000RS Digital camera, and a Itres' CASI-1500 hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. The PhaseOne camera imagery was collected at an altitude of 400m with a ground swath of 400m and delivered with a resolution of 5cm ground sample distance (GSD). Native PhaseOne imagery data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages process the imagery data into GIS-compatible products for visualization and further analysis. Horizontal positions, projected in Universal Transverse Mercator (UTM), are referenced to the North American Datum of 1983 (NAD83 2011). Vertical positions are referenced to the NAD83 ellipsoid. Individual image frames have been rectified and mosaicked into blocks commensurate with the collection blocks. Delivered data has been clipped to boundaries of Military Grid Reference System (MGRS). The data file naming convention is based on the year, project, area name, clip boundary, and product type. These file have been separated and delivered by JALBTCX collection blocks. An example file name is "2018_NCMP_NY_19TCF6388_RGB.tif", where 2018 is the year of data collection, NCMP is the Effort under which data were collected, MA is the area of data collection, the associated MGRS grid, and "RGB" is the product type. In rare cases file names may include whether data was collected at a nominal range of high tide (HT) or low tide (LT). The supplementary files are of the same name.

These data were collected as a part of the National Coastal Mapping Program (NCMP) to obtain imagery of conditions of the beach and near shore

The data positions were obtained using post processed Direct Georeference PPK methods. The horizontal accuracy of the true color imagery operation is 12.2cm at 95% Confidence Level with typical RMSE is 7.1cm. Gross offsets in imagery data may be due to DEM affects or unforseen timing offsets caused by missed or unknown camera trigger times.
