2018-2019 NOAA NGS 4-band Ortho-rectified Mosaic of Chesapeake Bay (Wilson to Airedele, MD)

Description

This orthoimagery data set includes 0.3 meter digital orthoimages in 8-bit 4-band (RGB-IR) GeoTIFF tiles. Geographic Extent: 3 counties in Maryland, covering approximately 535 total square miles. Dataset Description: The Chesapeake Bay NOAA Option 1 project called for the planning, acquisition, processing, and derivative products of imagery data to be collected at a ground sample distance (GSD) of 0.3 meter. Project specifications are based on the American Society of Photogrammetry and Remote Sensing (ASPRS) standards. The data were developed based on a horizontal projection/datum of NAD 1983 2011 UTM Zone 18N, Meter. Imagery data were delivered as 0.3 meter 8-bit 4-band (RGB-IR) GeoTIFF tiles. Tiled deliverables contained 154 individual 3000 m x 3000 m tiles. Ground Conditions: Imagery was collected in fall 2018 and spring 2019, while no snow was on the ground and rivers were at or below normal levels. In order to post process the imagery data to meet task order specifications and meet ASPRS horizontal accuracy guidelines, Quantum Spatial, Inc. utilized a total of 3 ground control points to assess the horizontal accuracy of the data.
