Imaging, Space, 20041001, C-CAP Classification for Washington Coastal Zone, Late-Date: NOAA Coastal Services Center, Charleston SC.Online Links:
Late Date (2000-era) Classification: This section outlines the classification procedure for the Washington C-CAP. The three dates of imagery were first reviewed for image quality and shifts between image dates. Training points were used as the dependent variable in a CART (Classification Analysis by Regression Tree) approach. Ancillary data layers were calculated from the TM data and were used as additional independent variables in the analysis. Different versions of the map were produced using different combinations of independent variables. The rough map represented the output from the CART classification routine. Ancillary data were used in spatial models were applied to the rough map to produce the provisional map. This represented a fully automated product. This product was then altered by hand edits to refine the classification. In addition, a percent impervious data layer developed from TM data using high resolution imagery, was imbedded into the classification to define the developed classes. This produced the final-with-edits version which is the final version of the classification and is the one described here. Pre-processing steps: Each Landsat TM scene was geo-referenced by USGS (United States Geological Survey) EROS Data Center. The Space Imaging staff reviewed the spectral and spatial quality of the imagery. Areas that were greater than 1-2 pixels off were sent back to USGS for reprocessing. The data was geo-referenced to Albers Conical Equal Area, with a spheroid of GRS 1980, and Datum of WGS84.
This data contains both 1995-era and 2000-era information. An accuracy assessment was completed for the 2000-era classification only because the ground truth was collected in 2002 and 2003.
While the accuracy of a 1995-era classification is hard to determine based on 2000-era ground truth, the 1995-era classification is composed of approximately 95.5% of the final 2000-era classification. This is because only the areas of change between 1995 and 2000 were classified for the early-date classification. Then the classified early-date layer was overlaid onto the late-date classification. Therefore the accuracy assessment for the late-date classification is still a good estimate of the accuracy of the early-date classification.
According to accuracy assessment performed by Space Imaging, the overall accuracy is 86.1% and 85.0% Kappa. The accuracy results shown below are from a combined accuracy completed on both Oregon and Washington
