Purpose: Coal overburden maps are fundamental to coal resource analysis. Regional views assist planners and policy-makers in their tasks.

Native_Data_Set_Environment: ArcView version 3.1 shapefile format \west\ncatest\ib\ib_heovrdd.shp Data_Quality_Information: Completeness_Report: Polygon files from the three states were converted to raster grids with 200-meter cell sizes. The individual grids were merged, then smoothed with a majorityfilter function, then converted back to vector polygon format. The most generalized attributes from the three states were used to ensure uniformity within the regional view.

Process_Step: Process_Description: (1) Component vector files were converted to 200-meter raster grids. (2) Grids were reclassified to consistent attribute scheme. (3) Grids were merged into one large grid, using the Arc "Merge" command. (4) Gaps along state boundaries were filled with the Arc "EuclidianAllocation" algorithm. (5) The Arc "Majority Filter" algorithm was run to remove speckles, and reduce sharp angles. (6) The final grid was converted back to vector polygon format. (7) A legend field was added to the attributes to supplement the grid codes.

They are areas within the outcrop extent of the coal beds where we have data essentially demonstrating zero coal thickness. In addition, given that these regional datasets are a compilation of data generated by each of the three states (Kentucky, Illinois, Indiana) within the Illinois basin, some dIscrepencies between states may exist. For instance, "Channels" have been defined and are represented in Illinois and Kentucky but have been extracted out of the coal extent in Indiana. In addition, some features have been defined as "Unassessed." These are areas which exist within the coal extent but have not been assessed and have no value.
