The data are geospatial and georeferenced to UTM Zone 16 NAD 83 GRS 1980. The data were derived from 1999 and 2000 Landsat 5 and Landsat 7 TM satellite imagery acquired between the dates of April 30, 1999 and October 10, 2000. The approximate scale is 1:100,000 with a ground resolution of 30 meters by 30 meters. The Illinois Gap Analysis layer is aggregated to 29 standardized categories for display purposes. Purpose: This database was completed as an integral part of the Illinois Interagency Landscape Classification Project. The purpose of this inventory is to provide a statewide characterization of land cover for Illinois. These data are intended for geographic display and analysis at the state level. The land cover data layer is provided "as is". IDNR/INHS/ISGS does not warrant results you may obtain using the data. Supplemental_Information: In addition to the Illinois Natural History Survey and the Illinois Department of Natural Resources, other state agencies participated and assisted in the creation of this dataset. These agencies include: Illinois State Geological Survey, Illinois Department of Agriculture, National Agriculture Statistics Service, and the Illinois GAP Analysis Project. ERDAS Imagine 8.5 is used as the Land Cover of Illinois 1999-2000's main image processing software.

Image processing is performed by ERDAS Imagine version 8.4 and later, 8.5 using UNIX and PC hardware. The land cover was prepared in *.img format. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Overall accuracy is estimated between 75% to 82%. Classification accuracy is 94.3% correct for agricultural-related land cover categories, which comprises 76% of the state. Additional information and complete accuracy assessment matrix can be found at: Land cover codes have been reviewed by INHS, IDNR, and NASS experts and are believed to be "good" at the time of satellite over flight. Agricultural land cover names were conceived by the National Agriculture Statistics Service. For a complete list of attributes, see the Data Dictionary located in the Entity and Attribute Information section of this metadata. Logical_Consistency_Report: The accuracy of the agricultural land cover classifications are evaluated using the extensive training data collected in the annual NASS June Agricultural Survey (JAS). The accuracy of the non-agricultural land cover classifications, except forests, are evaluated using a stratified random sample of points and interpreted through aerial photographs. The accuracy of the forest land cover classifications are evaluated using point locations from the INHS Critical Trends Assessment Project (CTAP) and USDA Forest Inventory Analysis (FIA) Program. Completeness_Report: All cells within the Illinois state boundary have an attributed cover type Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The categorized images are co-registered to EarthSat Inc's ortho-rectified GeoCover Stock Mosaic images using automated block correlation techniques. The block correlation is run against band two of each original raw satellite image and band two of the GeoCover Stock Mosaic. The resulting correlations are applied to each categorized image, and then added to a master image or mosaic using PEDITOR. The EarthSat images were chosen as they provide the best available large area ortho-rectified images as a basis to register large volume Landsat images.

Process_Step: Process_Description: Ten Landsat TM/ETM+ scenes which cover the state of Illinois were ordered with three dates of each scene. The three dates of each scene from spring-summer-fall were layer stacked to make one image composed of 18 bands. The satellite imagery for four of the TM scene areas was acquired in 1999, and the remaining six scene areas were acquired in 2000. Process_Step: Process_Description: All of the TM/ETM+ satellite imagery were geometrically corrected and co-registered to a transverse Mercator projection with a UTM zone 16 grid and NAD83 datum. The 1999 TM/ETM+ imagery is a mixture of simple geometric correction and terrain correction, while all of the 2000 imagery was terrain corrected using USGS 3 arc-second digital elevation model (DEM) data to correct relief displacement. Process_Step: Process_Description: 250 spectral classes were derived using an unsupervised classification. The labeling and reduction of the spectral classes from the unsupervised classification procedures into the final information classes (water, wetland, etc.) was accomplished by photo-interpretation of NAPP 3 aerial photography. Process_Step: Process_Description: The supervised classification of agricultural lands, which used USDA-NASS ground reference data as training data collected the same year for 425 sites across the state, directly resulted in information classes and therefore no additional class labeling was necessary. Process_Step: Process_Description: After class labeling was finished, forests were made into a raster mask. These masks pulled the 18 band raw data from each of the ten scenes. Slope Aspect Index (SAI) of the Digital Elevation Model (DEM) was added to the raw data within the forested areas to make 19 bands. The SAI was used to distinguish between upland and floodplain forests. Process_Step: Process_Description: Masks were made of the wetlands areas. The wetland delineation was accomplished through a combination of unsupervised classification of same year, spring-summer-fall Landsat TM/ETM+ imagery and photo-interpretation of 1998-1999 U.S. Geological Survey (USGS) National Aerial Photography Program (NAPP 3) photographic prints. Process_Step: Process_Description: Upon completion of the integrated classifications for each of the ten TM Path/Row scene areas, a seamless mosaic was created using image processing software developed by the USDA-NASS. Careful attention was made to develop the mosaic along county boundaries to ensure that the land cover information within each county area was derived from the same Landsat TM/ETM+ triplicate. Non-Agricultural classes were derived from an unsupervised classification and visual interpretation by analysts was made to determine categories.
