Description:

Abstract:

This is a final classification. This data set is the 2006-era classification of U.S. West Coast Region, zone 1. This data set utilized 11 full or partial Landsat scenes which were analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover.

Purpose:

To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

Attribute_Accuracy_Report:

According to the accuracy assessment performed by Space Imaging, the overall accuracy for the states of Washington and Oregon is 86.1% and 85.0% Kappa. The 2006 update is based on updating the change areas between 2001 and 2006 imagery, and overlaying the results over 2001 land cover. Therefore the accuracy of the 2001 product is a sufficient indication of 2006 update accuracy as well within +/- 4.25% (percent area change from 2001). The following methodology and results are from the accuracy assessment of the 2001 dataset conducted by Space Imaging: The accuracy results shown below are from a combined accuracy completed on both Oregon and Washington C-CAP areas. A total of 1043 points are located in Washington and 1165 points are located in Oregon. Each class accuracy is as follows: (Errors of Omission/Commission) 0 Background (N/A) 1 Unclassified (Cloud, Shadow, etc)(N/A) 2 High Intensity Developed (88%/98%) 3 Low Intensity Developed (99%/89%) 4 Cultivated Land (81%/79%) 5 Grassland (86%/81%) 6 Deciduous Forest (76%/81%) 7 Evergreen Forest (95%/90%) 8 Mixed Forest (80%/76%) 9 Scrub/Shrub (74%/88%) 10 Palustrine Forested Wetland (77%/78%) 11 Palustrine Scrub/Shrub Wetland (67%/70%) 12 Palustrine Emergent Wetland (83%/79%) 13 Estuarine Forested Wetland (N/A) 14 Estuarine Scrub/Shrub Wetland (N/A) 15 Estuarine Emergent Wetland (79%/79%) 16 Unconsolidated Shore (94%/96%) 17 Bare Land (88%/91%) 18 Water (98%/99%) 19 Palustrine Aquatic Bed (N/A) 20 Estuarine Aquatic Bed (100%/96%) 21 Tundra (N/A) 22 Snow/Ice (96%/100%) The validation points were both collected in the field and photo interpreted. The accuracy assessment selection methods were developed to minimize spatial autocorrelation between the training and accuracy assessment. The first pool of accuracy assessment sites came from field data and photo interpretation of black and white digital orthophotos and digital color infrared imagery (primarily Emerge and Ikonos data). These sites were collected prior to initial mapping and were collected at the same time as the training data. The sites were selected to capture the physical and spectral diversity of the land cover. After these sites were identified, they were separated into training and accuracy assessment sites by imposing a 1 km x 1 km grid over the study area. Accuracy assessment sites could only be selected from alternate 1 km squares. Only 1 sample per class was allowed from each potential square. After the first criteria was met, the accuracy assessment sites were buffered to see if they fell within 1000 meters of another accuracy assessment site of the same class or within 1000 meters of a training site of the same class. Those that fell within the 1000 meter buffer were eliminated. All sites were to be from a homogeneous 3x3 area. After an analysis of the point distribution, it became clear that there were not enough samples for every class. The remaining points were selected from the initial draft final classification and had to be a homogeneous 3x3 area. A stratified random sample was used to locate sites. These sites were restricted to the same alternate 1 km x 1 km grid that was used to separate training from AA sites in the initial analysis. Sampling was limited to areas where there was high resolution color infrared imagery. The imagery included the previous Ikonos and Emerge imagery, but also included an additional 60 scenes of Ikonos imagery. The additional Ikonos imagery provided sampling areas across the entire study area. When possible, we tried to identify 50 samples of the uncommon classes and 20 sites of the common classes. Samples were selected for the common classes so that there were samples for classes using this methodology. In total, an additional 637 additional points to the accuracy assessment analysis for a total of 2208. All classes have a minimum of 50 accuracy assessment points except for estuarine aquatic bed and estuarine emergent. These classes have 24 and 29 sites respectively. These classes are limited in the study area and to some extent in the imagery that was available to sample from. Post-Processing Steps: None Known Problems: None Spatial Filters: None

Logical_Consistency_Report:

Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.

Completeness_Report:

Data does not exist for all classes. There are no pixels representing class 16 (Estuarine Forested Wetland), class 17 (Estuarine Scrub/Shrub Wetland), class 24 (Tundra). Class 1 (Unclassified) is intentionally left blank. All pixels have been classified. The NOAA Coastal Change Analysis Program (C-CAP): Guidance for Regional Implementation, NOAA National Marine Fisheries Service Report 123, discusses the interagency effort to develop the land cover classification scheme and defines all categories.

Process_Description:

This dataset was created by MDA Federal. This classification is based on Landsat TM imagery from the MRLC 2006 database. The study area is zone 1, U.S. West Coast Region. Pre-processing steps: Each Landsat TM scene was geo-referenced by USGS (United States Geological Survey) EROS Data Center. Then MDA Federal staff verified the scenes for spatial accuracy to within 2 pixels. The data was geo-referenced to Albers Conical Equal Area, with a spheroid of GRS 1980, and Datum of WGS84. The data units is in meters. At-satellite reflectance was performed on each scene and the tasseled cap transformation applied. All of the image data used was Landsat TM 5 or 7. The mosaicked dataset was used for classification. Change Detection: The next step was to determine the areas of change between 2006 and 2001. The change detection algorithm used is the Cross Correlation Analysis process (CCA) developed at MDA Federal. This copyrighted procedure produced 2 Z-score files per scene of likelihood of change. These files were thresholded and mosaicked to create a binary change layer for that scene. All of the binary files were mosaicked to create a change layer for the entire study area. A focal majority was run on the change layer to fill in some clumps to make sure all of the change was accounted for. The change layer is a slight over-estimation of change to make sure to include as much change as detectable. Classification: The classification of the change areas was a mixture of automated and manual approaches. The change areas were removed from the 2001 classification. The areas with no change between 2006 and 2001 were used as training for a Classification and Regression tree (CART) analysis of the changed areas. Modelling and hand-editing were used to further refine the CART output and create a final classification. The classified change areas were overlaid on the 2001 C-CAP product to create a 2006 C-CAP classification. Attributes for this product are as follows: 0 Background 1 Unclassified (Cloud, Shadow, etc) 2 High Intensity Developed 3 Medium Intensity Developed 4 Low Intensity Developed 5 Developed Open Space 6 Cultivated Land 7 Pasture/Hay 8 Grassland 9 Deciduous Forest 10 Evergreen Forest 11 Mixed Forest 12 Scrub/Shrub 13 Palustrine Forested Wetland 14 Palustrine Scrub/Shrub Wetland 15 Palustrine Emergent Wetland 16 Estuarine Forested Wetland 17 Estuarine Scrub/Shrub Wetland 18 Estuarine Emergent Wetland 19 Unconsolidated Shore 20 Bare Land 21 Open Water 22 Palustrine Aquatic Bed 23 Estuarine Aquatic Bed 24 Tundra 25 Snow/Ice
