Lidar - Digital models (terrain, canopy, slope, level curve)

__The link: * Access the data directory is available in the sectionDataset description sheets; Additional information. Products derived from lidar (Light Detection and Ranging) are generated as part of the [__provincial lidar sensor data acquisition project] (https://mffp.gouv.qc.ca/documents/forets/inventaire/Analyse_retombees_lidar-Finale.pdf). It is therefore to facilitate the use of raw lidar data and optimize its benefits that the Ministry of Natural Resources and Forests (MRNF) generated and made available products derived from lidar in a user-friendly format. Lidar technology makes it possible to accurately provide information such as ground altitude, forest cover height (canopy), slopes, and contour lines. Here is the list of the five derived products: + Digital terrain model (spatial resolution: 1 m) + Digital terrain model in shaded relief (spatial resolution: 2 m) + Canopy height model (spatial resolution: 1 m) + Slopes (spatial resolution: 2 m) + Slopes (spatial resolution: 2 m) + Level curve (interval of: 1 m) This data covers almost the entire territory of Quebec south of the 52nd parallel. This map is distributed by map sheet at a scale of 1/20,000. Note 1: The resolution of the following products (digital terrain model, digital terrain model in shaded relief, canopy height model and slopes) has been slightly degraded in visualization in the interactive map to ensure efficient display. Note 2: The planimetric and altimetric accuracy of the curves is variable, but inevitably lower than that of the lidar surveys used to generate them. Moreover, it is recommended to use these level curves only for visual representations, and not for quantitative analyses.This third party metadata element was translated using an automated translation tool (Amazon Translate).*
