Mosaic of aerial orthophotographs from the ecoforest inventory of southern Quebec

The orthophotographs used to produce this mosaic are acquired by aerial overview in order to meet the needs of the Southern Quebec Ecoforest Inventory (IEQM). These images serve, among other things, to feed the process of photo-interpretation and production of the ecoforest map essential for sustainable forest management. This mosaic is the result of an assembly of orthophotographs produced since 2002 and represents the most recent images from the ecoforest inventory. The spatial resolution is generally 20, 21, or 30 cm (with some exceptions of 8, 10, 12, and 500 cm). Spectral bands and colors of images vary: black and white (panchromatic [PAN]), infrared (IRP), or natural (red, green, and blue colors [RGB]). This mosaic covers almost all of Quebec south of the 52nd parallel. The images used to produce the mosaic are acquired in a cycle of about 10 years corresponding to the IEQM calendar. Note that imagery acquired through partnerships was excluded due to their more restrictive distribution license and was replaced by historical images from the ecoforest inventory or by satellite imagery when the latter was not available. The orthophotography mosaic is accessible for visualization only using a web mapping service (WMTS).This third party metadata element was translated using an automated translation tool (Amazon Translate).
