Description:

Abstract:

This is a final classification. It is ready for distribution. This data set is the 2001-era classification of U.S. East Coast, zone 60. This data set utilized 25 full or partial Landsat 5 Thematic Mapper 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.

Supplemental_Information:

The metadata in this record is for USGS zone 60, which includes parts of North Carolina, Virginia, Maryland, New Jersey, Delaware, Pennsylvania, and New York.

Attribute_Accuracy_Report:

According to accuracy assessment performed by MDA Federal for U.S. East Coast, the overall accuracy for the zone 60 2001 classification is 71% and 67.3% Kappa.
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 (59%/87%) 3 Medium Intensity Developed (23%/39%) 4 Low Intensity Developed (28%/74%) 5 Open Spaces Developed (57%/67%) 6 Cultivated Land (91%/88%) 7 Pasture/Hay (87%/85%) 8 Grassland (63%/80%) 9 Deciduous Forest (84%/88) 10 Evergreen Forest (88%/96%) 11 Mixed Forest (43%/95%) 12 Scrub/Shrub (75%/64%) 13 Palustrine Forested Wetland (94%/84%) 14 Palustrine Scrub/Shrub Wetland (81%/68%) 15 Palustrine Emergent Wetland (77%/94%) 16 Estuarine Forested Wetland (N/A) 17 Estuarine Scrub/Shrub Wetland (N/A) 18 Estuarine Emergent Wetland (93%/100%) 19 Unconsolidated Shore (0%/NA) 20 Bare Land (97%/88%) 21 Water (100%/93%) 22 Palustrine Aquatic Bed (N/A) 23 Estuarine Aquatic Bed (N/A)
The validation points were sampled from the field collected dataset of points BEFORE classification. These points were witheld from classification and not viewed or modified by staff involved in the classification process. The sampling procedure involved a spectral/clump-based spatial stratification. The 2001 leaf-off MRLC mosaic was clustered to 100 clusters and clumped. This layer was divided into alternating clumps. The even clumps were sent to potential validation, odd to training. The process was repeated such that 1/4 of the field points were earmarked as validation points. These points were then reviewed for accuracy and placement by independent QC staff. Points that were not correct or too close to feature boundaries were either deleted or moved to more feature-centric locations. No points were added or changed, only moved or deleted. Probably over half of the points were modified. NOAA CSC requires 6 out 9 (2/3) pixels in a 3x3 window of the land cover to correctly match the validation points. The land cover was processed to determine the 2/3 majority call for each pixel and then intersected with the validation points in an error matrix to derive the above numbers.
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) and class 23 (Estuarine Aquatic Bed). 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 2001 database. The study area is zone 60, U.S. East Coast.
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.
Classification: The classification involved automated and manual approaches. Points collected during field work were used as training and also for accuracy assessment. The training points were used as the dependent variable in the CART (Classification Analysis by Regression Tree) approach. The tasseled cap Landsat TM imagery for three dates were used as the independent variables. Ancillary datasets were also used as independent variables. After many attempts, a rough classification was produced. The urban areas category was derived from the USGS impervious data set (2001-Era data) for zone 60. The result of this produced the provisional classification. Then models were applied to this data to incorporate information from ancillary data. The result of this was the final-no-edits version of the classification. This represented a fully automated product. This product was then altered by hand edits to refine further the classification. This produced the final-with-edits version which is the final version of the classification and is the one described here. 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
