Abstract: Streams is available for channel process study, evolution, and geomorphic change over time as well as for general reference and display

Procedure: The coverage streams was created by hand drawing channel features onto mylar sheets off of 1:5000 aerial photos (ortho-rectifited). Polygons and lines were then subsequently digitized and attributed. The coverages streams was created with the projection and coordinate system of UTM 12N, NAD27, and Clarke1866. This coverage was updated to UTM 12N, NAD83, and GRS1980 in February 2004. Projectdefine command in ArcINFO used to establish original projection in coverage. Project command in ArcINFO used to change datum.
