Charleston, South Carolina
Mission Linking People, Information, and
Technology in the Coastal Zone
- Strategic Focus Areas
- Coastal Hazards
- Coastal Watersheds
- Integrated Ocean Observing Systems
3Coastal Remote Sensing Program
Linking coastal resource managers with relevant
remote sensing technologies through
- Spatial data development
- Topography, land use/land cover, benthic,
imagery, etc. - Capacity Building Coastal Resource Management
- Outreach, training, technical support
- Geospatial tools development software
applications - Decision support, data manipulation
- Applied research and emerging technologies
- HABs, water quality, land use mapping, high-res.
Sensors, etc. - Outsourcing and contracting
- Private sector partnerships, CSC IDIQ contract
4The Coastal Change Analysis Program
Monitoring the Nations Coasts
- National coastal land cover and change mapping
program - Satellite-based map products
- Standardized data and methods
- Designed to help improve understanding of
linkages between land change and the environment
C-CAP Vision Develop national land cover change
products on a 5-year repeat cycle (or less).

8Making C-CAP Operational
Retooling
- C-CAP Effectiveness Review Panel (1999)
- 13 recommendations identified, including
- Utilize private sector partnerships
- Need for standard, consistent, timely products
- Leveraging other national efforts (minimize
duplication of effort) - Focus on applications customer orientation
(outreach effort) - Collaborative discussions with MRLC (2000)
- Consortium focused on nationally consistent
land cover data - NOAA, EPA, USFS, USGS are key members
- Decision to modify the C-CAP approach
- NOAA to continue focus on mapping in coastal
areas
9Making C-CAP Operational
Retooling
- Embracing MRLC database concept
- Innovative approach
- Common classification scheme
- Automated procedures (decision and regression
tree processing) - Standardized and accessible inputs
(ingredients) - Metadata tracking of procedures
- Repeatable processes
- Credibility

Continued Coastal Focus
- Focus on additional coastal categories
(Wetlands) - freshwater and estuarine
- Additional processing to meet 85 accuracy target
(categorical) - Additional field sampling and validation
- Utilization of change detection to produce

22High Resolution Land Cover
C-CAP Vision
Santa Cruz, CA
- Long term C-CAP vision / need
- and
- Increasingly available, high resolution imagery
and supporting data - provide
- New opportunities to
- Introduce new data streams
- Introduce new approaches
- Increase focus on coastal issues
- Provide data at a spatial scale more appropriate
for use in support of increasingly detailed, site
specific, management decisions.
23High Resolution Land Cover
Opportunities or Challenges?
- Budgetary Issues
- Reliable data streams will likely be commercial
() - Wall-to-wall classification over CONUS area
costly / impractical - C-CAP will need to prioritize where we work
- C-CAP will need to identify sources of future
funding - Technical Issues
- Data storage (data volume)
- Processing requirements (available software and
limitations) - Spectral resolution, bandwidth
- Lack of short wave infrared data
- Classification scheme and mapping accuracy
