Description:
Abstract:
The National Land Cover Database 2001 tree canopy layer for mapping zone 38 was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land cover Database (NLCD) circa 2001 for the United States at medium spatial resolution. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2003) and <http://www.mrlc.gov/mrlc2k.asp>.

The NLCD 2001 was created by partitioning the U.S. into mapping zones. A total of 66 mapping zones were delineated within the conterminous U.S. based on ecoregion and geographical characteristics, edge matching features and the size requirement of Landsat mosaics. Mapping zone 38 encompasses whole or portions of several states including the states of Nebraska, Kansas and Oklahoma . Questions about the NLCD mapping zone 38 can be directed to the NLCD 2001 land cover mapping team at the USGS/EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

Purpose:
The goal of this project is to provide the Nation with complete, current and consistent public domain information on its land use and land cover.

Attribute_Accuracy_Report:
Regression tree algorithms employed in NLCD 2001 mapping offer a cross-validation option for assessing classification and prediction reliability. Cross-validation can provide relatively reliable estimates for tree canopy predictions if the reference data used for cross-validation are collected based on a statistically valid sampling design. For mapping zone 38 tree canopy modeling, a 5-fold cross-validation was conducted by dividing the entire training data set into 5 subsets of equal size. For each model run, an accuracy estimate was derived using one subset to evaluate the model prediction (with the model developed using the remaining training samples). This process was repeated 5 times. After all 5 runs, an average value of all accuracy estimates and standard errors from the 5 runs were computed. Users should be cautioned that these cross-validation results provide users with only first-order estimates of data quality, and should not be considered a formal accuracy assessment.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: 87
Attribute_Accuracy_Explanation:
The above listed value is the overall accuracy obtained for tree canopy in the cross-validation study for mapping zone 38.
Logical_Consistency_Report:
18 1-m resolution DOQQs across mapping zone 38 were classified into either tree canopy or non-tree canopy areas, and then values summed within each 30 meter Landsat pixel cell to obtain the percentage of tree canopy.

Process_Description:
The method employed to map tree canopy density for NLCD 2001 consists of three key steps: deriving reference data of tree canopy density from the high spatial resolution images, calibrating density prediction models using reference data and Landsat spectral bands, and extrapolating the developed models spatially to map per-pixel tree canopy density. This method is described in detail in Huang et al. (2001). This approach was applied to mapping zone 38 by Sanborn Map Company.

Process_Description:
To develop adequate training data for tree canopy density estimation, 18 1-m resolution DOQQs across mapping zone 38 were classified into either tree canopy or non-tree canopy areas, and then values summed within each 30 meter Landsat pixel cell to obtain the percentage of tree canopy. The training data were selected based on the degree of variance each training data set possesses with regards to Landsat ETM+ imagery used for mapping. Each added training data set decreased the amount of variance present within the Landsat data as a whole. The process was repeated until the required number of samples had been allocated. By combining the training data with Landsat spectral data and other ancillary data, tree canopy prediction models were developed using "Cubist". After the best combination of possible input data layers had been determined and the final percent canopy density layer produced, a mask was made from the final land cover classification of the mapping zone and was used to eliminate those pixels from the canopy density file that fall into non-forested areas. The mask includes 5 land cover classes (deciduous forest, coniferous forest, mixed forest, woody wetlands, and developed open space).

Acquisition dates of Landsat ETM+ (TM) scenes used for land cover classification in this zone are as follows:
