This grid is one of three grids derived from the National Land Cover Database (NLCD 2001). The three associated grids provide data regarding land cover (LC2001USGS_IN), estimated percentages of tree canopy (TC2001USGS_IN), and estimated percentages of imperviousness (IS2001USGS_IN). These grids and their associated metadata were downloaded from the following Web site of the Multi-Resolution Land Characteristics (MRLC) Consortium:

Abstract:
IS2001USGS_IN is a grid (30-meter cell size) showing estimated percentages of impervious surfaces in Indiana in 2001. This grid is a subset of the National Land Cover Data (NLCD 2001) data set. Estimates of impervious surfaces are shown in this data set as percentages when the associated layer file (IS2001USGS_IN.LYR) is loaded.

The following is excerpted from metadata provided by the USGS for the NLCD 2001 (<http://extract.cr.usgs.gov/distmeta/servlet/gov.usgs.edc.MetaBuilder?TYPE=HTML&DATASET=NLCD01IMPV&YMAX=39.611501479289956&YMIN=39.611501479289956&XMIN=-76.63165680473374&XMAX=-76.63165680473374>):

"The National Land Cover Database 2001 impervious surface layer for mapping zone 60 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) 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 is 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, edgematching features and the size requirement of Landsat mosaics. Mapping zone 60 encompasses whole or portions of several states in the mid-Atlantic region, including the states of New Jersey, Delaware, Maryland, Pennsylvania, Virginia, and the District of Columbia. Questions about the NLCD mapping zone 60 can be directed to the NLCD 2001 land cover mapping team at the USGS EROS Data Center (EDC), Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov."

Purpose:
IS2001USGS_IN provides estimated percentages of impervious surfaces for Indiana, derived the National Land Cover Database (NLCD 2001). This data provides the most complete, current, and consistent public domain information for Indiana land use and land cover.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The following is excerpted from metadata provided by the USGS for the NLCD 2001:

"The information on data quality for mapping zone 60 was generated by the Decision Tree algorithm that conducts a cross-validation for assessing classification and prediction reliability. No formal independent accuracy assessment of mapping zone 60 imperviousness has been made. The regression tree algorithm employed in NLCD 2001 mapping offers a cross-validation option for assessing classification and prediction reliability. Cross-validation can provide relatively reliable estimates for imperviousness predictions if the reference data used for cross-validation are collected based on a statistical valid sampling design. For mapping zone 60 imperviousness 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 from the 5 run's 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."

Completeness_Report:
The following is excerpted from metadata provided by the USGS for the NLCD 2001:

"This NLCD product of mapping zone 60 Imperviousness layer is the version 1 dated 09-01-2003.

"The NLCD 2001 database for mapping zone 60 consists of three main data products including: (1) per pixel classified land-cover data (2) sub-pixel percent imperviousness and (3) sub-pixel percent tree canopy density. The land-cover database also includes three additional metadata layers that provide users a spatial node map of the land cover classification, a spatial confidence map of the land cover classification, and a text file of logical statements pertinent to the land cover classification. The three layers are: (1) a spatial node map of the land cover classification, (2) a spatial confidence map of the land cover classification, and, (3) a text file of logical statements related to the land cover classification. These additional metadata layers may be of interest to some data users with specific needs. If you are interested in the detailed metadata information, please refer to <http://www.mrlc.gov> ."

The following information was excerpted from information provided by the USGS and the Multi-Resolution Land Characteristics (MRLC) Consortium:

"The method employed to map percent imperviousness for NLCD 2001 mapping zone 60 consists of three key steps: deriving reference data of imperviousness 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 imperviousness. This method is described in detail in Yang et al. (2003). This method was applied to mapping zone 60 by Earth Satellite Corporation (through Greenhorne & O'Mara Inc.) under USGS contract."

Process_Description:
Personnel of the Indiana Geological Survey used the Multi-Resolution Land Characteristics (MRLC) Consortium's interactive viewer and download tool (found at <http://www.mrlc.gov/mrlc2k_nlcd.asp>) to download two raster tiff images showing estimated percentages of impervious surfaces for the Indiana portion of the National Landcover Database (NLCD 2001).

The "Data Preparation > Mosiac Images" command from the ImageAnalysis extension (version 9.2, build 8.9.1.204) in ESRI ArcGIS 9.2 was used to mosaic the two images into one tiff image for Indiana. The "Data Preparation > Subset Images" command was then used to clip the image to the Indiana boundary. The output image was then saved as an ESRI Grid named "IS2001USGS_IN". IS2001USGS_IN was then projected to Universal Transverse Mercator, Zone 16, NAD 1983.
