Project Information
http://alaska.usgs.gov/portal/project.php?project_id=350
This dataset is comprised of 36 black and white 9x9 inch aerial images of four different study areas on Alaska's Arctic Coastal Plain taken between 1948-1949 and obtained from the Alaska Satellite Facility in 2013. The images represent an historical snapshot of the landscape from that time.
The images were scanned and geo-referenced to various contemporary (2002-2010) satellite imagery using tie-point methods and splines for interpolation.
The purpose of this data set is to assess changes in vegetation or landforms during the 20th century that may be related to climate change and impacts on critical wildlife habitat.
Contact John Pearce, USGS Alaska Science Center, with questions about these images and associated data.

Coordinate values were obtained by geo-referencing the images to various contemporary (2002-2010) satellite imagery using tie-point methods and splines for interpolation.

The data are complete
The 37 black and white 9 x 9 inch vertical aerial photographs from 1948 and 1949 with sub-meter native resolution were scanned at higher resolution than the grain of the film; these were georeferenced in ArcMap 10.1 using >20 distributed tie-points per image and splines to modern 2.5-m scale satellite imagery. The geo-referenced photos created contiguous coverage for each of the blocked study areas. A color-infrared aerial photo mosaic from July 18, 2002, and a SPOT mosaic from the growing season (green period) of 2009-10, served as baseline imagery for geo-referencing and for the qualitative landscape change detection.
Lab
Historical imagery (1948-1949) was obtained for four main study areas on the Arctic Coastal Plain of Alaska, where a portion of on-going USGS Changing Arctic Ecosystems (CAE) research is focused. These areas were (1) the Smith River and Garry Creek drainages in the coastal zone of the Teshekpuk Lake Special Area (TLSA Coast), (2) an interior lake area west of Teshekpuk Lake (Chipp River), (3) coastal areas of the Colville River Delta (Colville Delta), and (4) 10 locations along the Dalton Highway between the Brooks Range and Deadhorse, Alaska (Dalton Highway Corridor). Images were black and white 9 x 9 inch photographic prints from 1948 and 1949 and obtained from the Alaska Satellite Facility (ASF) at the University of Alaska Fairbanks (https://www.asf.alaska.edu/).
