This dataset has been updated to include locations that were previously not included. The source data for this updated in the "Heads of Tide for Coastal Streams in Oregon", March 1989.
This dataset was originally generated by R. Sounhein (2000) from the Heads of Tide for Coastal Streams in Oregon study conducted by DSL in the late 1980, and reviewed by G. Willnow. The digitization of the report’s tidal data was conducted against 1:24,000 USGS Quads and 1:24,000 Digital Ortho Quads dating from 1995 and reviewed and QA/QCed by the original DSL staff (Greg Willnow and Perry Lumley) that generated the original report and also verified in the field by R. Sounhein and G. Willnow during the Waterway Inventory Project of 1997-2000.
All digitization was conducted against 1:24,000 USGS Quads and 1:24,000 Digitial Ortho Quads of 1995 vintage. The data integrety is determined from High (visual onsite) to Low (nonvisual) with the recorded Date and Personnel name. |
