The link: Access the data directory is available in the section Dataset Description Sheets; Additional Information . The polygonal layer of lidar slope classes expresses the slope of the terrain. The slopes are generated from a digital terrain model (DTM) with a resolution of 10 meters. The latter is the result of an aggregation by bilinear interpolation of lidar NCDs at 1 m. The minimum area of the resulting polygons is 0.2 hectares. Lidar digital slopes are divided into 7 classes. + A - Null by [0 to 3]% + B - Low from] 3 to 8]% + C - Soft from] 8 to 15]% + D - Moderate [from] 15 to 30]% + E - Strong from] 30 to 40]% + F - Steep from] 40 to ∞ [% + S — Summit completely surrounded by F slopes This map covers the entire territory of the Southern Quebec Ecoforest Inventory (IEQM) and was developed in order to provide stakeholders with the tools they need when applying for financial assist Publisher: Government and Municipalities of Québec | Gouvernement et municipalités du Québec (via Open Government Canada).
