PCI Geomatics announced the completion of a project to process historical airphotos for the GIS department of Fairfax County, VA. In 2017, the county GIS team contacted PCI Geomatics to help correct its remaining historical airphotos from 1960 and 1976. The 1976 imagery was particularly unique as it was the first color imagery collected of the entire county. The experts at PCI Geomatics used its Geomatica Historical Airphoto Processing software to produce accurate, complete, high-quality ortho mosaics of the data. The county had recognized the long-term value of historical imagery and invested in preserving the information contained in older images through systematic scanning and ortho mosaicking. The county GIS team also created Historical Image Viewer, an innovative and easy-to-use app, available through its web portal, to showcase historical ortho mosaics. Tom Conry, GIS Manager at Fairfax County said, “We have added the 1960 and 1976 imagery to the existing 12 years of historic imagery in Historical Image Viewer.”
