Frequently-anticipated questions:


What does this data set describe?

Title: Stream (streams)
Abstract:
This layer is composed of the streams on the Siuslaw National Forest. The layer has line data associated with it. The original data for the stream layer was obtained from the geometronics service center as 1:24000 quad maps of digital data. The layer was updated in 1992 and 1993 with data obtained under contract with Jim Kiser at Oregon State University who used a digital stereoscope to interpret controlled 1989 B/W 1:40,000 scale photos. Many additional class 3 and 4 streams were added. Locations of some of the GSC original GSC streams were adjusted where clearcuts in the more recent photography allowed more accurate placement. Where discrepancies occurred between the original GSC streams and Kiser's streams based on differences in photo interpretation, the stream lines which best fit the 1:24,000 base photos were selected. Lines were later added through the centers of lakes and rivers for continuity.
Supplemental_Information:
Additional streams, existing stream locations, and stream attributes will be updated from project-level surveys as they occur.
