Downloading Data
While the workshop folder you downloaded contains some prepared data for Vancouver, knowing how to search for geospatial data and download it from the web is an important skill to have. Therefore, this page will guide you through downloading different kinds of geospatial data from municipal repositories. If you haven’t already:
Example: Downloading Parks from Calgary’s Open Data Portal
Downloading geospatial data from municipal data portals isn’t always straightforward. It can be tricky to find the right buttons to press to downlaod the right file format. Remember that if there’s an interactive map vizualizing geospatial data, there is likely a way to access and download the data in a spatial format (e.g., shapefile, geodatabase, or geoJSON).
Either geoJSON or shapefile will do.
