Parcel Viewer's aerial imagery is updated

2012 aerial imagery sampleA new countywide set of aerial photographs is now available to users of Parcel Viewer (2.0). Thousands of images were captured during a coordinated series of flyovers in early spring of 2012, and have been processed into a seamless mosaic for use in a wide variety of mapping applications. Users of Parcel Viewer can now view contemporary property information against aerial photo backgrounds that represent four different years: 2012, 2009, 2007, and 1936 (western King County only). Read on here for more information about the 2012 aerial imagery acquisition project, which featured collaborative participation by dozens of jurisdictions and agencies throughout the central Puget Sound area.
