Dataset Description: The PEMA 2020-2021 0.5-Foot Orthoimagery project called for the planning, acquisition, processing, and derivative products of imagery data to be collected at a ground sample distance (GSD) of 0.5 foot. 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 HARN StatePlane Pennsylvania Feet, Foot US.. Ground Conditions: Imagery was collected in winter 2020 and 2021, 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, NV5 Geospatial utilized a total of 496 ground control points to assess the horizontal accuracy of the data.<o:p></o:p>
