New GIS-based Tools Available Online
Two new Web mapping interfaces were released on the Illinois State Geological Survey (ISGS) Web site. Both integrate address-based location information from Google Maps with the dynamic presentation of ISGS GIS data.
The ILMINES viewer displays an overview of coal and non-coal mine data that will assist the public in determining if the land area of interest may be undermined; the viewer also provides dynamic links to additional coal mine-related maps and reports that contain detailed information. The Illinois Public Land Survey System (PLSS) Locator tool locates an Illinois address and displays township, range, and section information, as well as longitude and latitude coordinates and the U.S. Geological Survey 7.5-minute quadrangle name for the point of interest.
Introductory text describes how to use each map viewer and briefly explains the ISGS data presented.
