Title: Gap Northern Lower Peninsula Land Cover

Series_Name: Land Cover, Land Use

Description:

Abstract:: Land cover data for the Northern Lower peninsula of Michigan, specifically section 7 of Albert's ecoregions for Michigan, derived from classification of Landsat Thematic Mapper imagery. Image dates between 1992-1994 were used to identify 32 land cover classes. The data is stored in a raster format with a cell resolution of 30 meters. Data is available in Erdas Imagine 8.3.1 image format. Data is in the Michigan Georef coordinate system.
Purpose:: This data was developed as a part of the Michigan GAP analysis project. Information produced by the Michigan GAP program will help provide an overview of the distribution and management status of Michigan's wildlife and land cover biodiversity. The land cover data set is only one product of MI GAP, but is critical for vegetation distribution and associated wildlife species distribution modeling.
Supplemental_Information:: See "Data_Quality_Information" section for image acquisition dates. See "Entity_and_Attribute_Information" section for class list and class definitions. Classification was done for the Michigan DNR (MIDNR) by Maclean Consultants Ltd. (Houghton, MI). Ancillary data used during the classification effort included digital National Wetland Inventory, MIRIS 1978 land cover, Albert's ecoregions of MI, and aerial photography at various scales. A post classification accuracy assessment was also carried out using both aerial photography and ground truthing. Finally, the data was checked by MIDNR using MIRIS, USGS, and other data sources. Some classes were aggregated in the final product due to class confusion in the original classification. For more complete treatment of the classification protocol, see the "Draft WISCLAND/Upper Midwest Gap analysis program image processing protocol, Version 1.5" by Lillesand et al. (1995, final version 1998) - available from the Upper Midwest Environmental Sciences Center of the USGS (<http://www.umesc.usgs.gov>). Exceptions to the Upper Midwest image processing protocol included: 1) agricultural training and accuracy assessment sites were identified in a similar fashion to non-agricultural areas 2) radiometric normalization reference sites were not identified 3) single date imagery was used for the Lake Michigan islands and the Alpena area of Region 6 Mio 4) Albert's (1994) ecological subsection boundaries helped guide the delineation of SCCUs from TM imagery. 5) urban and excavation areas were manually extracted through examination of USGS 1:100,000 scale maps rather than via TIGER files 6) wetlands were not separated from uplands on the Lake Michigan islands due to the lack of digital NWI data for these islands at the time of image classification. 7) post classification accuracy assessment was designed to randomly select SCCU/land cover combinations and assign an adequate sample size to result in a significant test of accuracy. Approximately 1475 accuracy assessment locations were evaluated. All SCCUs with the exception of Region 2sw and the Lake Michigan islands contained accuracy assessment locations; however, not all cover types were assessed in each SCCU. MIDNR black and white infrared aerial photography (1:15840, 1997-1999, leaf on) was primarily used for the accuracy assessment.

Attribute_Accuracy_Report:

The accuracy of the vegetation and land cover map was assessed in great detail. A post classification accuracy assessment was carried out using both aerial photography and ground truthing. Post classification accuracy assessment was designed to randomly select spectrally consistent classification units (SCCUs) and assign an adequate sample size to result in a significant test of accuracy. Approximately 1475 accuracy assessment locations were evaluated. Overall accuracy for all 1475 points was 80.20 percent with a Kappa (Khat) value of 0.7837. All SCCUs with the exception of Region 2sw and the Lake Michigan islands contained accuracy assessment locations; however, not all cover types were assessed in each SCCU. MIDNR black and white infrared aerial photography (1:15840, 1997-1999, leaf on) was primarily used for the accuracy assessment. See below for overall accuracy figures for each class. For more complete treatment of the accuracy assessment (including error matrices for each SCCU), see the MI-GAP Northern Lower Peninsula land cover final report (available from MIDNR).
