Mapping
The goal of the ISGS mapping program, begun in 1996, is to
map the entire state's geologic units, from land surface
to bedrock, at a detailed scale of 1:24,000. Reliable,
detailed information is essential to making good decisions
about the complex issues affecting our state's water, land,
energy supplies, and aggregate resources.
The ISGS has also been working since 1997 through partners
in the Central Great Lakes Geologic Mapping Coalition to
map the region's surficial deposits and bedrock surface.
The ISGS three-dimensional geologic mapping program intends
to meet this information need. Using the latest
technological tools and methods, survey geologists create
detailed geologic maps and models that help planners and
communities develop, manage, and protect water resources;
locate and economically extract mineral resources;
construct buildings and transportation corridors; install
utilities; safely dispose of wastes; and plan for efficient
and beneficial land use.
An ISGS economic study indicates that the dollar value to
society of detailed geologic maps is 25 to 29 times the
cost of the mapping program!
