PEMA 2018 0.5-foot Orthoimagery (US Survey Feet); Orthophoto MrSID (25:1 compression); File: Erie-1

Metadata Updated: August 15, 2019

Product: This orthoimagery data set includes 0.5-foot (15-centimeter) 8-bit 4-band (RGBN) digital orthoimage mosaics in MrSID format (25:1 compression). Geographic Extent: The Erie County AOI covers approximately 810 total square miles (2,098 total square kilometers) in the vicinity of the City of Erie in the Commonwealth of Pennsylvania. Dataset Description: The PEMA 2018 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 (15 centimeters). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Ortho Specification, Version 1.0. The data were developed based on a horizontal projection/datum of NAD83 (2011) State Plane Pennsylvania North FIPS 3701, US Survey Feet. Orthoimagery data were delivered as 4 MrSID [4-band (RGBN)] mosaics (25:1 compression). Ground Conditions: Aerial photography was captured during the spring of 2018, 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 horizontal accuracy guidelines, Quantum Spatial, Inc. utilized a total of 496 QC points throughout the Commonwealth of Pennsylvania to assess the horizontal accuracy of the data. These checkpoints were not used to calibrate or post process the data.
