Title: Nooksack River orthophotos - 1938

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 the Army Corps of Engineers, 4735 East Marginal Way South, Seattle, Washington 98134-2329. This image dataset was created from 133 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.

Date: Photo 286 says "(M286-21M-91) (10-19-38-IP) (12-12000) NOOKSAK RIVER WASHINGTON"

Scale: approx. 1:12,000

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/>).
