Putting the Pacific Islands
on the National Map
Overview of Coastal Change Analysis Program (C-CAP)
Christine FeinholzNOAA Pacific Services Center
The Coastal Change Analysis Program
• National coastal land cover and change mapping program
• Inventory of intertidal areas, wetlands, and adjacent upland, produced/updated every 5 years
• Consistent, accurate products through standard data and methods
• Coastal Expression of the National Land Cover Database (NLCD)
“Designed to help improve understanding of linkages
between land change and the environment”

• Hawaiian islands will be part of the 2001 National Land Cover Database (NLCD) effort
– NOAA and USGS cooperative effort
• Derived from 30 meter Landsat multispectral imagery
• A “re-release” of existing land cover information for the islands
– C-CAP and HI GAP (2001)– We are not remapping the islands– This is not an updated land cover
• 2005 products being produced based on high res production
Moderate Resolution Land Cover
Moderate Resolution Impervious
• NLCD product categorizes amount of man-made impervious surface in each 30m pixel
– Values range from 0 to 100%
• Derived directly from the Quickbird impervious maps
– Not a training based classification
• Used to directly classify 30m developed categories
– i.e. High, Medium, Low Intensity
High Resolution Impervious
• Derived from 2.4 meter Quickbird multispectral imagery (2005)
• Provide detailed information on location and extent of man-made impervious surfaces
• Developed in partnership with State of Hawaii Office of Planning
• Available now for 7 of the main 8 islands of Hawaii and Guam
– Island of Hawaii available shortly– Hawaii is 75% complete due to clouds
High Resolution Land Cover
• Derived from 2.4 meter Quickbird multispectral imagery (2005)
• More detailed and up-to-date than previously available land cover information
• Island of Oahu Available now– AA to be complete Summer 2008
• Islands of Maui, Molokai, Lanai, and Kahoolawe in-progress
– Will be released as completed– Anticipated to be complete by
December of 2008
Land Cover Tools N-SPECT
- Non-point Source Pollution and Erosion Comparison Tool
- Downloadable GIS extension
- Inputs: Land Cover, Elevation, Precipitation, Soil Characteristics,
- Predicts surface water runoff, nonpoint source pollution, and erosion.
- Land Cover Change Scenarioshttp://www.csc.noaa.gov/crs/cwq/nspect.html
Land Cover Tools HPP
- Habitat Priority Planner
- Downloadable GIS extension
- Inputs: Land Cover, project specific points, lines, or polygons
- Inventory habitat conditions
- Identify, rank, and prioritize conservation sites
- Analyze proposed changes in land use or land cover

Land Cover Tools Digital Coast Land Cover Atlas
- Online Land Cover Summary and Analysis Website
- Summarizes Land Cover for user defined areas
- Will not require GIS software
- Publicly Available
