The Tesselle Forest Information System (SIFORT) is a system that was created in order to meet various needs for analysis and knowledge data on Quebec territory. SIFORT is a database composed of polygonal units of 15 seconds (latitude) by 15 seconds (longitude), whose average area is approximately 14 hectares. Information from the tesserla is obtained by assigning the forest data to the centroid of the tesserla. Thus, for each of the tesserae, we find information such as the type of cover, the type of disturbance of origin, the year of the disturbance, the species, the density, etc. This system integrates forest information from the various forest inventories (first, second, third, third, third, third, third, fourth and fifth inventories, when available) and offers the advantage of constituting a fixed analysis grid in space. Making it possible to relate the forest composition of the territory to the various natural disturbances (e.g. fire and insects) and forest interventions, SIFORT makes it possible to feed various statistical and temporal studies and analyses whose objective is to ensure the sustainable management of Quebec's forest territory.This third party metadata element…
