GIS, Illinois State Water Survey

Geographic Information Systems (GIS)

Since 1982, the Illinois State Water Survey (ISWS), along with the other Illinois Scientific Surveys, has led the State of Illinois in implementing GIS technology for its public agencies. During this time, computer hardware and software performance has increased dramatically, while costs have decreased. Advanced GIS capabilities, which previously required expensive workstations, are now available to GIS professionals on their desktop PCs.

The mission of Geographic Information Systems (GIS) at the Illinois State Water Survey is to promote and facilitate the use of GIS technology in water and atmospheric resources research; provide accurate, timely and accessible geographic information to researchers, decision-makers, and Illinois citizens; and develop innovative applications to expand the field of GIS-assisted research.
