Description:

This orthoimagery data set includes 0.5 foot 8-bit 4-band (RGBN) digital orthoimage tiles in GeoTIFF, Mr. SID, and JPEG 2000 (JP2) format. Dataset Description: The PEMA 0.5-Foot Orthoimagery Delivery (US Survey Feet) 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 North FIPS 3701 Feet, Foot US. Ground Conditions: Imagery was collected in spring 2022, 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 119 ground control points to assess the horizontal accuracy of the data.
