Welcome to the Lake County GIS Department
It is estimated that more than eighty percent of governmental functions are associated with managing information about specific locations or geographic areas. A Geographic Information System (GIS) is a computer system for the input, editing, storage, maintenance, management, retrieval, analysis, and output of geographically referenced information. GIS supports applications such as emergency dispatch, land planning, emergency management and Homeland Security, property appraisal, civil engineering, natural resource monitoring, transportation planning, monitoring crime and accidents, public health and environmental analysis, economic development, census analysis, and many more.
