The Forest Information System by Tesselle (SIFORT) is a system that has been created to meet various needs for analysis and knowledge data of Quebec territory. SIFORT is a database composed of polygonal units of 15 seconds (latitude) by 15 seconds (longitude), with an average area of about 14 hectares. The information of the tesselle is obtained by assigning the forest data to the centroid of the tesselle. Thus, for each of the shellas, information such as canopy type, original disturbance type, year of disturbance, gasoline, density, etc. This system integrates forest information from the various forest inventories (first, second, third, fourth and fifth inventories, where available) and provides theadvantage of building a fixed analysis grid in space. Allowing to link the forest composition of the territory with various natural disturbances (e.g. fire and insects) and forest interventions, SIFORT allows to feed various statistical and temporal work and analyses aimed at ensuring sustainable management of Quebec's forest territory.
