These digital terrain models (DTM) offer a regional numerical representation of Quebec's relief based on altimetric (altitude) and planimetric (rectangular or geographic) data. They are the result of a collaboration between the Ministry of Natural Resources and Forests (MRNF) and Natural...

The ecological classification of Quebec territory consists of mapping and describing ecological units in a system with nine levels of perception between the continental and landscape scales. It presents the diversity of terrestrial ecosystems in all of Quebec taking into account both the...

TOPEX (acronym which means “topographical exposure”) is an index of topographic exposure. It reflects the influence of local topography on the degree of exposure to wind and on its behavior (Ruel et al. 2002). TOPEX data are presented in the form of a matrix file (raster) whose spatial resolution...
