These three satellite mosaics cover the entire territory of Quebec and include images taken in 2018, 2019 and 2020. The spectral bands are blue (band 2), near infrared (band 8), and short wave infrared (band 11). The Copernicus Sentinel-2 mission includes a constellation of two satellites in...

Municipalities with established populations of Ixodes scapularis ticks (blacklegged ticks) are municipalities where tick populations reproduce and survive from one year to the next. This indicator makes it possible to identify municipalities where their presence suggests a higher risk of tick...

This map illustrates the terrestrial and marine reliefs of Quebec and surrounding territories, at a scale of 1/2,000,000. Color ranges representing altitude classes and blending offer a summary of the relief and the major physiographic groups of Quebec. This map of the relief of Quebec is...

These mosaics are the result of an assembly of orthophotographs produced in spring 2022. Each image has been positioned geographically taking into account the effect of the relief. * These mosaics are the result of regional partnerships. Their download is free, as they were acquired under an...

The temporary sample plot is a circular sample unit that covers an area of 400 m2. For each tree, we observe and measure the species, diameter, sunlight, and floor in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In...

The temporary sample plot is a circular sample unit that covers an area of 400 m2 (the main unit). For each tree, we observe and measure the species, diameter, and stage in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In...

Digital terrain models offer a representation of the relief south of the 52nd parallel, in the form of an elevation matrix. This matrix makes it possible to visualize the territory in perspective and to perform three-dimensional spatial analyses, using appropriate software. A module specialized...
