- 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.

- 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
