The original ecoforest map of the third inventory is made from aerial photographs as well as several other products to inform the photointerpreter (forest interventions, information concerning natural disturbances, data from previous inventories, etc.). This map shows the various forest and ecological characteristics of the forest territory and corresponds to the forest profile up to the year in which the aerial photograph was taken.
To learn more about ecoforest stratification parameters, simply consult Chapter 3 of the document [Ecoforest Mapping Standards — Third Ecoforest Inventory (MRNF, 2009) ] (https://mrnf.gouv.qc.ca/documents/forets/inventaire/norme-cartographie-ecoforestiere.pdf).
Note that the original ecoforest map of the third inventory has been complete since 2003 and that no new cartographic information has been added since then. Note, however, that improvements were made to the dataset format in 2025.This third party metadata element was translated using an automated translation tool (Amazon Translate).
