NOAA's Coastal Change Analysis Program provides nationally standardized data on land cover and land use collected every five years. It includes high resolution data for several Pacific islands at 2.4m resolution. This level of detail is useful for small-scale analysis, extracting specific land cover components, and site-specific studies. The high resolution data has been used for applications like vulnerability assessments, studying climate change impacts, and modeling sediment erosion. It is made more useful through data products like the Land Cover Atlas, sea level rise viewer, and other tools to analyze and understand the land cover data.

Editor's Notes
- Provide an overview of the C-CAP high resolution product line Development framework Lessons learned Topics to be covered Imagery Image Segmentation Classification Change Detection Land Cover Atlas Applications of C-CAP in the pacific
- General Overview of C-CAP: -History of C-CAP -What is C-CAP -Where can C-CAP be found Effort housed at Office for Coastal Management Discuss federal partnerships Discuss how C-CAP fits into the National Picture (coastal expression of NLCD), etc. Coastal Focus! Added focus on wetland
- Moderate Resolution covers 25% of CONUS Produced through a change detection/update mapping process Multiple dates of maps available High resolution mostly in Near Estuarine Research Reserves (NEERs) and US Island Territories in the Pacific and Caribbean
- Change masks are available for in-between years
- Interested in smaller mapping projects Mention C-CAP in Hawaii One of the driving forces behind the initiation of the high res c-cap product line Discuss differences between High Res and Moderate Res Direct response to customer needs
- Compare/contrast photos Highlight individual feature extraction (houses) in high resolution
- Address the common misconception that higher resolution makes the work easier. Show landsat image (common moderate res image) vs worldview-2 (common high res image)
- Interested in smaller mapping projects Mention C-CAP in Hawaii One of the driving forces behind the initiation of the high res c-cap product line Discuss differences between High Res and Moderate Res Direct response to customer needs
- Increased level of spatial detail Wells Maine Impact (Detail Standardized, semi-automated process
- Steps Baseline data Identify areas (i.e. via Change Mask) Collect training data Classify change area Insert into baseline map
