Abstract:
The National Land Cover Database 2001 tree canopy layer for mapping zone 66 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 66 encompasses whole or portions of several states including the states of Maine, New Hampshire, and Vermont. Questions about the NLCD mapping zone 66 can be directed to the NLCD 2001 land cover mapping team at the National Center, 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.

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 66 by Sanborn Solutions.

Process_Description:
To develop adequate training data for tree canopy density estimation, 30 1-m resolution DOQQs across mapping zone 66 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 landcover 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: SPRING- Index 1 for Path 10/Row 29 on 05/17/03 = Scene_ID 7010029000313750 Index 2 for Path 11/Row 27 on 05/16/03 = Scene_ID 5011027000313610 Index 2 for Path 11/Row 28 on 05/16/03 = Scene_ID 5011028000313610 Index 3 for Path 11/Row 29 on 04/29/00 = Scene_ID 7011029000012050 Index10 for Path 11/Row 30 on 04/14/03 = Scene_ID 5011030000310410 Index 6 for Path 12/Row 27 on 05/12/02 = Scene_ID 7012027000213250 Index 8 for Path 12/Row 28 on 05/25/01 = Scene_ID 7012028000114550 Index 7 for Path 12/Row 29 on 05/04/02 = Scene_ID 5012029000212410 Index 9 for Path 12/Row 30 on 05/09/01 = Scene_ID 7012030000112950 Index 4 for Path 13/Row 29 on 05/08/01 = Scene_ID 5013029000112810 Index 4 for Path 13/Row 30 on 05/08/01 = Scene_ID 5013030000112810 Index 5 for Path 14/Row 29 on 05/07/01 = Scene_ID 7014029000112750 LEAF ON (Summer)- Index 1 for Path 10/Row 29 on 06/28/01 = Scene_ID 7010029000117950 Index 2 for Path 11/Row 27 on 08/09/02 = Scene_ID 7011027000222150 Index 2 for Path 11/Row 28 on 08/09/02 = Scene_ID 7011028000222150 Index 2 for Path 11/Row 29 on 08/09/02 = Scene_ID 7011029000222150 Index 2 for Path 11/Row 30 on 08/09/02 = Scene_ID 7011030000222150 Index 3 for Path 12/Row 27 on 07/20/01 = Scene_ID 5012027000120110 Index 3 for Path 12/Row 28 on 07/20/01 = Scene_ID 5012028000120110 Index 4 for Path 12/Row 29 on 05/25/01 = Scene_ID 7012029000114550 Index 5 for Path 12/Row 30 on 06/21/02 = Scene_ID 5012030000217210 Index 6 for Path 13/Row 29 on 06/04/02 = Scene_ID 7013029000215550 Index 7 for Path 13/Row 30 on 08/31/99 = Scene_ID 7013030009924350 Index 8 for Path 14/Row 29 on 06/08/01 = Scene_ID 7014029000115950 LEAF-OFF (Fall)- Index 1 for Path 10/Row 29 on 10/02/01 = Scene_ID 7010029000127550 Index 2 for Path 11/Row 27 on 10/04/02 = Scene_ID 5011027000227710 Index 3 for Path 11/Row 28 on 10/01/01 = Scene_ID 5011028000127410 Index 4 for Path 11/Row 29 on 10/22/00 = Scene_ID 7011029000029650 Index 5 for Path 12/Row 27 on 09/30/01 = Scene_ID 7012027000127350 Index 5 for Path 12/Row 28 on 09/30/01 = Scene_ID 7012028000127350 Index 6 for Path 12/Row 29 on 10/16/01 = Scene_ID 7012029000128950 Index 7 for Path 12/Row 30 on 10/16/01 = Scene_ID 7012030000128950 Index 8 for Path 13/Row 29 on 10/12/00 = Scene_ID 5013029000028610 Index 9 for Path 13/Row 30 on 10/20/00 = Scene_ID 7013030000029450 Index 9 for Path 14/Row 29 on 10/12/03 = Scene_ID 5014029000328510 Landsat data and ancillary data used for the tree canopy - Data Type of DEM composed of 1 band of Continuous Variable Type.
