Service Description:

2006 3" pixel resolution orthoimagery of the city of Portland ME. Provided by the Maine Office of GIS and the Maine GeoLibrary Board. Portland 2006 3" orthoimagery - As the prime contractor, Bradstreet Consultants, Inc. used the aerial photography flown in one session on April 26th, 2006, by Richard Crouse & Associates, Inc. of Frederick, MD who acquired approximately 1335 photos @ 1"=600' with airborne GPS using a Wild RC-30 (#13261) aerial camera. Bradstreet Consultants, Inc. painted and repainted ground targets for photo survey control points (~200) to support full analytical aerotriangulation. The aerotriangulation solution was used to set up each stereopair of photos for orthorectification and DTM compilation. The ortho imagery was created by scanning (14 microns (um) per pixel or 1815 dpi) the original 1"=600' scale film and employing a digital terrain model (DTM) from updating some town's original DTM and some town's from scratch using the 1"=600' scale negatives or diapositives using both analytical and softcopy (digital) stereoplotter in the Kork KDMS format.
