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 all of the south of the province. This map is distributed by map sheets at a scale of ** 1:20,000. __ ⚠️ 1) Note that__ the resolution of the following products (digital terrain model, digital terrain model in shaded relief, canopy height model and slopes) has been slightly degraded when viewed in the interactive map to ensure a powerful display. __ ⚠️ 2) Note that__ the planimetric and altimeter accuracy of 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).**
