Canadian Urban Environmental Health Research Consortium (CANUE) Data Dictionary

The Canadian Urban Environmental Health Research Consortium (CANUE) consists of compiled and derived standardized environmental exposure data about air quality, green spaces, walkability, noise, climate and extreme weather and other aspects of the urban/suburban environment for linking to human health research platforms. Specifically, using geographic information systems and satellite imagery to obtain geospatial and temporal data.
