North American Environmental Atlas

Home » North American Environmental Atlas

Mapping Our Shared Environment

The North American Environmental Atlas combines and harmonizes geospatial data from Canada, Mexico and the United States to allow for a continental and regional perspective on environmental issues that cross boundaries. It is a unique tool to analyze and raise awareness of our shared environment and ecosystems across the continent, to demonstrate their value, and to help us see what needs to be done to protect them.

The dozens of map layers of the Atlas are unique in that they harmonize geographic information across North America’s political boundaries. By comparing these map layers, we can better understand and quantify critical trends and interrelationships at the North American level.

Explore this interactive story for a better understanding of how the Atlas can be useful to you.

Explore more than one thousand publications and articles that utilized data from the North American Environmental Atlas.
