This image dataset was created from 14 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. 1:20,000

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/>).

Attribute_Accuracy:

Quantitative_Attribute_Accuracy_Assessment:

Logical_Consistency_Report:

Photos received from Geoengineers were georeferenced at their offices, and have somewhat lower accuracy and image quality. Those photos (the minority) were mosaicked with the orthophotos produced by the River History Project.

Completeness_Report:

Images cover the river bottoms and some of the adjacent uplands for the White River from approximately RM 0 to RM 17.
