Proposal to Oregon Geographic Information Council (OGIC)Framework Data Development Program
for the 2015 – 2017 Biennium
OverviewWhat is the Shoreline Working Group effort all about?
o Workgroup of the Coastal Marine Data Network FITo A Team that reviews shoreline datasets, agrees upon appropriate use, and
documents those findings.
• What is the overall goal of this project? To develop/adopt a set of standardized datasets that can be shared and exchanged with the Oregon GIS community.
From NOAA FAQ: What is the legal U.S. shoreline?There is no legal reference that designates one specific shoreline as the legal shoreline. Furthermore, there is no simple answer to this question as there are many legal, technical, and general uses of the terms related to shoreline (shoreline, coastline, baseline, mean high
water line, mean low water line, etc.).
Working Group Approach:
3 meetings (with online components) 2012-2014o Communications handled through announcements to the Oregon Coastal and Marine Data
Network (OCMDN) listserv ([email protected] )

Discussion surrounding NOAA CUSP Shoreline and uses in Oregon
To match application/intent of data use to the appropriate resource
NOAA has released a new Shoreline Product (CUSP)
Thanks to : Stephen White and Doug Graham from the Remote Sensing Division of NOAA’s National Geodetic Survey, for a great overview of NOAA shoreline products and activities.

NOAA Continually Updated Shoreline Product (CUSP)
OCMP has created an “Oregon-enhanced” CUSP
New Data Set generated using similar methods to the NOAA CUSP, focused on making the best shoreline for Oregon, including estuaries

Benefits of CUSP• Authoritative source
(NOAA)
• Known vintage
• Known datum
• In Oregon, virtually all of the outer CUSP coast is derived from lidar
• In Oregon, OCMP has generated compatible estuarine shorelines from lidar (using CUSP methods)
NHD-CUSP Comparisons
Issues with NHD Coastline• The origin of “Coastline”
geometry in NHD is largely unknown (probably DLG)
• The south coast is particularly poor
• Same for the shoreline portions of “NHDWaterbody” and “NHDArea”
• The NHD Standard specifies Mean High Water (MHW) for the coastline
• CUSP is a great opportunity to meet the NHD standard with authoritative geometry
What will it take?• The process will require the existing NHD
coastline to be stripped out of the NHDFlowline Feature layer, and edge-matched to the new NOAA shoreline.
• Existing NHD flowlines will need to be reconnected to the coastline to maintain the NHD flow network,
• Water areas represented in the NHDArea and NHDWaterbody feature classes will be updated accordingly.
• Finally, the watershed boundaries at the HUC8 level (WBDHU8) will also need to be updated to be made compatible with the new line work.
What will it take?• The work will be done on a watershed by
watershed basis, as dictated by NHD editing practices and tools.
• Overall 13 HUC8 watersheds will be touched, approx 3-4 per quarter
Deliverable Timeframe
Phase I: Work Plan coordination, and development of Edit Methods work flows
6 months
Phase II: Mechanical NHD-CUSP integration work (by HUC8)
Quarter I: Chetco, Lower Rogue, Sixes 9 months
Quarter II: Coquille, Coos, Umpqua 12 months
Quarter III: Siltcoos, Siuslaw , Alsea, Siletz-Yaquina 15 months
Quarter IV: Wilson-Trask-Nestucca, Nehalem, Necanicum 18 months
Phase III: Review loop built in for any data clean up required by USGS 18-22 months
*Note: Elapsed time from project start date.
Process• Phase I: work with USGS and NRCS and
members of PNW Hydro to establish a preferred data integration workflow
• Phase II: DOGAMI NHD editor to edit coastal NHD watershed by watershed, with quarterly frequent check-ins to ensure progress and verify results
• Phase III: Reserved for feedback loop with NHD stewards and any needed editing clean-up
