  • What is GIS?

    GIS stands for "geographic information system", essentially a computer-based mapping system for capturing, storing, analyzing and managing data and associated attributes. GIS data is said to be "spatially referenced", meaning that it is tied to geographic locations as points, lines, or areas.

    GIS makes it possible to work with multiple information "layers" concerning various geographic features at a known place or within a defined area. Layers can be of many different types of information such as roads, water bodies, parcels, wards, utility systems, aerial images, topography, and more. GIS also provides ways to easily view and examine relationships between these layers.
