Illinois Map 14: Bedrock Geology of Illinois
Compiled in 2005, this statewide, 36 x 54 inch full-color map includes much more detail about the state's bedrock geology than was previously available. Complex geologic features on the map, such as the bedrock geology near Hicks Dome in Hardin County, are shown in exploded view. The new information on the map was gleaned during the most recent 10 years of Survey mapping. Side 1 contains the map itself, the areas mapped since 1967, a legend, and explanation of symbols. Side 2 displays two large cross sections, one the width and the other the length of the state. A highly detailed stratigraphic column is shown. Several smaller maps portray other aspects of Illinois geology, including Sub-Kaskaskia geology, Sub-Absaroka (Pennsylvanian Period) geology, Quaternary geology, Sub-Tippecanoe geology, structural features, and the top of the Precambrian. Wirelog information and references are given also. 1:500,000 scale (1 inch on the map represents about 8 miles).

Illinois Map 12: Illinois Land Cover
The 2004 Illinois Land Cover map was produced in response to a need for current, detailed information about Illinois land, the raw material of the state. This land cover information for twenty-six identified categories is essential to ensure wise land-use decisions and good land stewardship. The satellite image data used to construct the map revealed that more than 76% of Illinois land is devoted to agriculture, primarily corn and soybeans, followed by forested lands (11.5%), urban and built-up lands (6.5%), wetlands (3.9%), and surface water (1.7%). A great companion to the Illinois Surface Topography map. The map is 36 × 53 inches; map scale 1:500,000.

This 2003 statewide map shows the state's land surface in unprecedented detail, revealing regional structures and landforms that are too subtle to recognize on previous topographical maps. This amazing image of the state was created by using digital elevation data and by exaggerating the vertical scale twenty times. Lighting, shading, and color tinting techniques used in the map's production allow the reader to spot easily the landscape features such as floodplains, hills, river valleys, and glacial moraines. This full-color map should be interesting to a wide range of Illinois residents and especially useful to educators, planners, scientists, businesses, farmers, and government bodies. Size is 36 × 54 inches; map scale is 1:500,000.
