Polygonal slope class from lidar

The link: Access the data directory is available in the sectionDataset 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 from [0 to 3]% • B - Low from] 3 to 8]% • C - Soft from] 8 to 15]% • D - Moderate from] 15 to 30]% • E - Strong from] 15 to 30]% • E - Strong from] 30 to 40]% • B - Low from] 3 to 8]% • C - Soft from] 8 to 15]% • D - Moderate from] 15 to 30]% • E - Strong from] 15 to 30]% • E - Strong from] 30 to 40]% • E - Strong from] 30 to 40]% • F - Steep from] 40 to 40]% • F - Steep from] 40 to ∞ [% • S — Summit entirely surrounded by slopes F 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 assistance from the Forest Management Investment Program (PIAF). We do not recommend using the information in this layer for detailed analysis. This third party metadata element was translated using an automated translation tool (Amazon Translate).
