      Title: White River orthophotos - 1936
      Geospatial_Data_Presentation_Form: raster digital data
  Description:
    Abstract:
      This dataset is part of a large collection of historical aerial photographs that were orthorectified. This set of photos was acquired from Terry Butler of King County Department of Natural Resources and Parks, Water and Land Resources Division, Seattle, WA. This image dataset was created from 33 individual photos (stored in TIFF format) which were orthorectified, mosaicked, and tiled into rectangular sections approximately 4900+ meters by 7000+ meters. (Sections are roughly the extents of slightly overlapping USGS Digital Ortho Quarter-quads found at <http://duff.ess.washington.edu/data/raster/doqs/>). Data does not necessarily fill each section completely.

      Scale: approx. 1:10,000

    Supplemental_Information:
      Black and white photographs (approx 9" X 7" prints) were scanned at 600 pixels per inch, grayscale, and saved as TIFF files. Performed "Auto Levels" in Photoshop and used Photoshop to change all pixels of value 0,0,0 to 1,1,1 (to avoid dropout of 0,0,0 pixels when turning off display of background value 0 in ArcMap). Resulting TIFF images were then orthorectified using ERDAS Imagine's OrthoBASE module. Registration sources were USGS Digital Ortho Quarter-quads (<http://duff.ess.washington.edu/data/raster/doqs/>) and a USGS 10-meter DEM (<http://duff.ess.washington.edu/data/raster/tenmeter/byquad/>).
