The land use and development plan puts forward a frame of reference aimed at better knowing, protecting and promoting heritage. The data available in this set mainly comes from the mapping of sections 2.1, 2.3 and 3.1 of the Urban and Urban Plan of Montreal, namely __adaptation to climate change__, __territories of ecological interest__, __territories of ecological interest__, the __green and blue frame__, the __green and blue frame__ as well as __constraints and nuisances__. This urban planning and development plan for the agglomeration of Montreal outlines the main parameters that will guide the Montreal agglomeration council in decisions relating to land use planning in the coming years. From a perspective of sustainable development, this document guides decisions that shape the territory in order to promote compact and greener neighborhoods, increase public and active transportation, support the economic dynamism of the agglomeration and highlight areas of interest. Consult the [interactive map] (https://smvt.maps.arcgis.com/apps/webappviewer/index.html?id=d152aaa85b6f4e9086cecdf10c7456db) of the Planning and Development Plan to visualize the thematic data.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This Shaded Relief Image has a resolution of 300 meters and was derived from the /Yukon 90m Shaded Relief/ from Environment Yukon, the /Canada 3D/ elevation model from Natural Resources Canada, and the United States Geological Survey /1:250k DEM of Alaska/.

__The link: *Access the data directory* is available in the section*Dataset 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).**
