So you want to make a Map: Where and How to find Data (QGIS)

Описание: Before you get started with GIS, you need data. This session shows you how geospatial data is made and collected, the types of formats that can be brought into QGIS, and a variety of local data sources.

The version of QGIS that is used in this video is 3.40.11.

To help access the data used in the exercise, here are the links:
• Sampling Data - https://ed.marine-geo.canada.ca/index...
• Coastline Data - https://natural-resources.canada.ca/s...
• Elevation/Bathymetry Data - http://www.ngdc.noaa.gov/mgg/image/2m...
