Canada’s land surface is covered with different vegetation types, built environments, water, desert, rock, ice and snow formations. Natural Resources Canada uses remote sensing data to accurately and efficiently map this vast area.
Studying Canada’s Land Cover from Space
The Canada Centre for Remote Sensing (CCRS) at Natural Resources Canada uses data collected by Earth observation satellites to produce accurate, efficient and cost-effective data and images of Canada’s land cover.
How it works
To produce land cover datasets, remote sensing scientists compile cloud-free mosaics from thousands of satellite images collected in the short summer months when snow and ice cover is lowest. Then, using advanced machine learning techniques and complex algorithms developed and verified through fieldwork, CCRS scientists use high performance computing to identify land cover types within the images.
Why is land cover important?
Land cover characterizes many environmental and economic elements, including weather, migration patterns, agriculture and forestry production, where people can live, the availability of clean water, and the frequency and severity of natural hazards.
Understanding land cover means knowing where surface features on the earth are located, where one type of land cover ends and another begins, and how they are changing over time. Understanding land cover is vital to:
- Inform emergency preparedness strategies, resource development and ecosystem studies
- Understand environmental change and cumulative effects (the effects of human activities on the landscape
- Monitor the impacts of climate change and inform adaptation
