Q: What is a Municipal Geographic Information System (GIS)?

A: A GIS is an “information system” that stores and manages data. These systems are not just software and hardware, but also, and most importantly, the collection of information about where geographic features (roads, buildings, fire hydrants, pipes, crime incidents, ponds, streams, etc.) are located and information associated with these features (age, material, size, etc). Building this database involves compiling the information from maps and/or aerial photos, card files, staff’s personal experience, and existing databases. A GIS integrates all this information so that it can be used together and is accessible through a single program operating on a single computer by presenting multiple layers of data to the end user all referenced back to a single point on a map. Not only does a GIS make sharing information amongst council and staff much easier and consistent, it also facilitates sharing information with others (ratepayers, other communities, etc.) more efficient.
