Since the late 1990’s, the City of Solon has been utilizing GIS services to assist city staff in their work. In 2005, the city successfully launched its first public GIS interface. In February 2011 the city replaced the former GIS interface with improved functionality. Today, Solon's GIS serves the needs of nearly every city department and the general public.
GIS stands for Geographic Information System(s). Here are a couple of quotes to help answer the question:
“In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system.” USGS
“A geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps.” ESRI
