The ecoforest inventory north of the northern limit of attributable forests is an extensive inventory that was carried out for specific knowledge acquisition needs. It was carried out between 2005 and 2009 as part of the work of the scientific committee responsible for examining the northern limit of attributable forests (Nordic Ecoforest Inventory Program [PIEN]). The data in this inventory comes from a cartography that is based both on the use of archival aerial photographs interpreted in three dimensions on the screen and on the analysis of satellite images. This dataset covers the territory between the 50th and 53rd parallel and covers an area of 242,000 km2. It includes forest and ecological mapping data (vegetation, surface deposits and drainage) as well as ecodendrometric sample plot data. This data is distributed by map sheet at a scale of 1/250,000. The minimum mapping area is 8 ha for stands and 4 ha for surface deposits.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

These digital terrain models (DTM) offer a regional numerical representation of Quebec's 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. NCDs are obtained as a result of hypsometric and hydrographic data processing that uses the concept of hydro-coherence that uses the concept of hydro-coherence consisting in interpolating altimetric values by ensuring a connected drainage network and an accurate representation of crests and river courses. water. The oriented RHN filament makes it possible to grade lakes and to control the altimeter descent of watercourses. The final product is a quality portrait of relief on a scale of 1/50,000. DNTs 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).**
