The Coastal Change Analysis Program (C-CAP) produces national coastal land cover maps every 5 years using consistent data and methods. C-CAP maps land cover for coastal areas, including wetlands and adjacent uplands. High resolution 2005 land cover and impervious surface maps have been completed for many Hawaiian islands using Quickbird satellite imagery. Moderate resolution 2001 land cover maps also exist and will be re-released as part of a national effort. The maps and analysis tools help understand coastal environment changes.

2. 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
“Designed to help improve
• Coastal Expression of the National
Land Cover Database (NLCD) understanding of linkages
between land change and the
environment”

8. Moderate Resolution
Land Cover
• 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

9. 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

10. 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

11. 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
