Geographic Information Systems (GIS): Geospatial Data Sources

A guide on GIS and mapping-related resources

About Data

In order to use GIS, you will first need to feed data into your GIS software/tool in order to start creating visualisations and performing analyses based on your data. Any type of data can be used, as long as there is some kind of location component such as an address or postal code, for example. 

As first step, it is necessary to find and download data that can be added to your base map. This page lists some sources by category, with a focus on geospatial data. For other types of themed data, refer to Research Guides
