Slope class (BDTQ)

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. Slope classes express the slope of the land in a relatively homogeneous area with a minimum area of 0.5 ha. They are generated from a numerical model that groups terrain slopes into six classes: + Zero of 0-3% + Low of 4-8% + Mild of 9-15% + Moderate of 16-30% + Strong of 31-40% + Strong of 31-40% + Steep of 41% or more These data cover almost the entire territory of Quebec south of the 52nd parallel. This map is presented in two groups: grouping at the provincial level and grouping at the scale of 1/250,000. Each grouping represents an assembly of sheets produced on a scale of 1/20,000. The datasets were originally produced in 2005 and then updated in 2006. In 2010, they were enhanced with slope information for the northernmost part. No updates have been made since then. __For more information, please refer to the document: [Products presenting the concept of slope] (https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Classes_pente/1-Documentation/Produits_presentant_la_notion_de_pente.pdf) __ __Note:__ The numerical terrain model is prepared from the level curves and altitude points that come from the topographic map at the scale of 1/20,000 and 1/50,000 from the Quebec Topographic Database (BDTQ). This geographic database was produced in 2010 and has never been updated. __Former name:__ Numerical slope classes, Slope class**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
