McGill Library holds a significant collection of maps, atlases, air photos, satellite imagery, and data covering the greater Montreal region, the province of Quebec, Canada, and the rest of the world.
The links below provide information about the location of each collection as well as details about how materials can be accessed or requested.
McGill Library collects geospatial data primarily for the Montreal region, secondarily for Quebec, Canada, and the United States.
