The Interagency Working Groupon Ocean and Coastal Mapping (IWG-OCM)
• Co-chaired by NOAA, USGS, and USACE
• Charged with facilitating “the coordination of ocean and coastal mapping activities and avoid[ing] duplicating mapping activities…”
WHO:NOAAUSGSUSACENAVOBOEMNSFNGAUSCGEPAFEMANASAand other appropriate Federal agencies involved in ocean and coastal mapping.

National Coastal Mapping Strategy 1.0Coastal Lidar Elevation for a 3D Nation
• GOAL: – To survey and map the
Nation’s coasts and nearshore areas for multipurpose use
– Avoid duplication and maximize efficiency
• Requires: – Coordination– Broad Range of Partners– A Plan!

National Coastal Mapping Strategy 1.0Coastal Lidar Elevation for a 3D Nation
What is it?• Version 1.0
focused on coastal topo-bathy lidar
• Version 2.0:– Offshore/OCS– Based off
NOAA OCS Hydro Health Model
USGS analysis of 2012 NEEA Study ROI of lidar data, based on multiple-use requirements /uses
Shallow water bathymetryShoreline delineation
Topobathy DEM’sRegional sediment
managementLand/water interface
mappingHabitat mapping
Bottom type detectionCoastal erosion monitoring
Navigation/Charting
Uses of Topo Bathy Lidar Data:
Coastal vulnerability assessments
Infrastructure assessmentTsunami inundation
modelingEmergency responseScientific research on
processes of coastal changeCoral reef ecologyCoral reef genesis
Ecosystem connectivity

Example Applications
QL0B Bathymetric Lidar
0.25, 0.0075 ≤0.7 ≥2.0 Detailed site surveys requiring the highest accuracy and highest resolution seafloor definition; dredging and inshore engineering surveys; high-resolution surveys of ports and harbors
QL1B Bathymetric Lidar
0.25, 0.0075 ≤2.0 ≥0.25
QL2B Bathymetric Lidar
0.30, 0.0130 ≤0.7 ≥2.0 Charting surveys; regional sediment management General bathymetric mapping; coastal science and management applicationsChange analysis; deepwatersurveys, environmental analysis
QL3B Bathymetric Lidar
0.30, 0.0130 ≤20 ≥0.25
QL4B Bathymetric Lidar
0.50, 0.0130 ≤5.0 ≥0.04 Recon/planning; all general applications not requiring higher resolution and accuracy

National Coastal Mapping Strategy 1.0
Component 4: Consensus on targeted research and development
Topo-bathy lidar and other coastal mapping technologies are rapidly evolving
Federal coastal mapping R&D programs critical Smart to leverage capabilities and stretch limited research dollars
Mutual interest areas include:• New sensor technologies (to improve quality and timeliness of
data collection)• Algorithms (to process raw data and create usable data and
products)• New uses for data (e.g., coastal management and science
questions)

National Coastal Mapping Strategy 2.0 Building from coastal focus to include offshore/Outer Continental Shelf
region Focus on including priority requirements from IWG-OCM agencies to
start (e.g. NOAA Hydro Survey Priorities, NOAA habitat mapping, BOEM lease/sand/gravel areas, state CZM areas, and more)
Timeline:Winter/Spring 2017 – Drafting of Strategy Summer 2017 – Interagency Review (via IWG-OCM) Fall 2017 – WH Subcommittee on Ocean Science & Technology
reviewWinter 2018 – Federal Register Notice to solicit public comment on
draft strategy Spring 2018 – Address comments, final review via IWG-OCM and
SOST Summer 2018 – Post final version to IWG-OCM website.
