Digital terrain models offer a representation of the relief south of the 52nd parallel, in the form of an elevation matrix. This matrix makes it possible to visualize the territory in perspective and to perform three-dimensional spatial analyses, using appropriate software. A module specialized in three-dimensional data processing, such as 3D Analyst or Spatial Analyst, is required to visualize the digital altitude model in three dimensions. This digital altitude model (10-meter pixel matrix) is obtained by processing altimeter data (level curves and elevation points) from ** [topographic databases on a scale of 1/20,000] (https://www.donneesquebec.ca/recherche/fr/dataset/cartes-topographiques-a-l-echelle-de-1-20-000) **.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The dataset comprises a topographic map of Northeast Greenland delivered as a digital elevation model (DEM) with a spatial resolution of 8 metres. The DEM is provided as GeoTIFF and represents a seamless elevation surface covering the study area. The dataset was produced using input data from the ArcticDEM project, which is based on stereo imagery from the DigitalGlobe WorldView-1, WorldView-2 and WorldView-3 satellites. The elevation model integrates selected DEM strips recorded between 2012 and 2015 and has been processed to ensure consistency and continuity across the mosaic.

__The link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. As part of the provincial LiDAR sensor data acquisition project, a topographic humidity index or *Topographic Wetness Index* (TWI) was produced from the digital terrain model derived from aerial LiDAR (*Light Detection and Ranging*). The matrix layers thus produced provide information on the potential for water accumulation on the territory as a function of the slope and accumulation at a given pixel.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

### #Des hydrocoherent numerical terrain models (MNT-HC) are also offered south of the 52nd parallel. They are accessible via the [High Resolution Quebec Hydrographic Network Geobase (GRHQ-HR)] (https://www.donneesquebec.ca/recherche/dataset/geobase-du-reseau-hydrographique-du-quebec-a-haute-resolution-grhq-hr) These hydrocoherent numerical terrain models (DTM — HC) offer a regional numerical representation of Quebec relief based on altimetric (altitude) and planimetric (rectangular or geographic) data. They are the result of a collaboration between the Ministry of Natural Resources and Forests (MRNF) and Natural Resources Canada (NRCan) within the framework of the Agreement to produce an up-to-date digital map of northern Quebec and the creation of the product “National Hydro Network (RHN)” for the territory of Quebec. When integrated into a geographic information system, these models allow the implementation of multiple types of spatial analyses such as natural risks, landscape analysis, infrastructure implementation, etc. Hydrocoherent MNTs are obtained as a result of hypsometric and hydrographic data processing that uses the concept of hydrocoherence, which consists in interpolating altimetric values by ensuring a connected drainage network and an accurate representation of ridges and watercourses. The oriented RHN filament makes it possible to grade lakes and to control the altimetric descent of watercourses. The final product is a quality portrait of relief on a scale of 1/50,000. DMTs provide altitude values that are based on a grid with a resolution of 0.324 arcseconds in geographic coordinates, which corresponds to a resolution of about 10 meters in the field.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
