Welland Maps and GIS

A geographic information system (GIS) is a computer software package of linked databases and applications used for capturing, storing, analyzing, manipulating, integrating, and displaying map information.


Information is input as layers in a GIS software program. For example, one layer can be for roads, water bodies, parks, forests, etc. When you overlay these layers, your view will be similar to a paper map.

The City of Welland uses the Esri® suite of GIS software. The core of Welland’s GIS is a centralized database. The City’s GIS data is stored in the database and includes roads, water and sewer mains and valves, hydrants, catch basins, trees, property parcels, zoning, aerial and satellite imagery, and civic addresses, just to name a few. The GIS is used for many purposes, including infrastructure planning and management, planning applications and processes, day-to-day operations and maintenance management, asset inventories, and 3-D surface modelling. Numerous data holdings are available to view when using the interactive mapping site.
