Title: Dungeness River orthophotos - 04-11-2001

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:

Byron Rot Habitat Program Manager Jamestown S'Klallam Tribe 1033 Old Blyn Hwy. Sequim, WA 98382 ph (360) 681-4615 fax (360) 681-4643

(Photos shot by the now defunct Sound Aerial Surveys, Inc., 7777 Perimeter Road South #8, Seattle WA 98108, 206.763.1603, project 01-1011, date 4-11-01)

This image dataset was created from 17 individual color 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. 1:5900

Supplemental_Information:

Color photographs (approx 9" X 9" prints) were scanned at 600 pixels per inch, RGB, 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 Leica Photogrameetry Suite module (formerly OrthoBASE). Registration sources were USGS Digital Ortho Quarter-quads (<http://duff.ess.washington.edu/data/raster/doqs/>) and a 2-meter Lidar DEM from Ralph Haugerud and the Puget Sound Lidar Consortium (<http://duff.geology.washington.edu/data/raster/lidar/>), with some limited reference to a USGS 10-meter DEM (<http://duff.ess.washington.edu/data/raster/tenmeter/byquad/>) where the Lidar coverage did not exist.
