Historic airborne forest imagery

Historic airborne forest imagery corresponds to an annual collection of orthophotographs, acquired by aerial survey in order to meet the needs of the Southern Quebec Ecoforest Inventory (IEQM) and the global forest planning cycle (operational forest planning, forest monitoring and forest activity monitoring). These images serve, among other things, to feed the process of photo-interpretation and production of the ecoforest map essential for sustainable forest management, as well as the global forest planning cycle. Historical orthophotographs are assembled into mosaics. Each mosaic groups together images from an acquisition project that have the same year of shooting, the same spatial resolution and the same color. Mosaics have been produced since 2002 for ecoforest inventory and since 2004 for planning, monitoring and control images. The spatial resolution is generally 20, 21, or 30 cm (with a few exceptions of 50 and 63 cm) for the images that make up the ecoforest inventory mosaics, while it is much more variable for planning, monitoring, and control images (from 4 to 150 cm). The color type of the images varies: black and white (panchromatic [PAN]), infrared (PIR), or natural (red, green, and blue [RGB] colors). The images used to produce the mosaics are distributed over almost the entire territory south of the 52nd parallel of Quebec's public forest. They are acquired in a cycle of about 10 years for the IEQM and annually for the needs of the global forest planning cycle. Note that imagery of territories acquired through partnerships has been excluded from the mosaics. Orthophotography mosaics are accessible for viewing only, using a web mapping service (WMTS). Indexes, representing the outlines of the boundaries of historical airborne forest imagery acquisition projects, are also available as a web service (WMS, WFS) or as a downloadable file (SHP).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
