A series in the south (266 sheets) and a series in the north (151 sheets) of the 53rd parallel cover the majority of Quebec. The data is less than 10 meters accurate and each file covers an area of approximately 4,000 km2, equivalent to 16 sheets at [a scale of 1/20,000] (https://www.donneesquebec.ca/recherche/fr/dataset/cartes-topographiques-a-l-echelle-de-1-20-000 “Topographic maps at a scale of 1/20,000”). Main components: * Hydrography (lakes of more than three hectares, permanent watercourses, swamps, etc.). * Vegetation (wooded areas and peatlands of more than 13 hectares). * Human constructions: * transport infrastructures (motorable roads, bridges, airports, etc.); * buildings larger than 12,500 m2; * buildings larger than 12,500 m2; * equipment and designated areas. * The relief (level curves at an equidistance). of 20 meters and elevation points). ##### Special features of the series south of the 53rd parallel * The data are obtained by a generalization of map data on a scale of 1/20,000. Between the 51st and the 53rd parallel, they are extracted from SPOT satellite imagery at 10 meters of resolution. * The data formats available for this series are: * Cover ArcInfo (vector); * GeoTIFF, CCL projection (matrix); * GeoTIFF, MTM projection (matrix); * GeoTIFF, MTM projection (matrix); * PDF (matrix); * PDF (matrix). ##### Special features of the series north of the 53rd parallel * The data is obtained by a generalization of map data from Natural Resources Canada (CanVec product) at a scale of 1:50,000. Multi-source data, namely data from Adresses Québec, data on airports and hydrobases from the Ministère des Transports du Québec, and data on reservoirs from Hydro-Québec, increase the quality of this cartographic product on a scale of 1/100,000. * The data format available for this series is: * FGDB (vector).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

They cover almost all of the territory south of the 52nd parallel. The data is extracted from aerial photographs at a scale of 1:40,000 taken at an altitude of 6,300 meters. They offer an accuracy of approximately four meters in planimetry. In hypsometry, it is about two meters for dimensional points and about five meters for level curves. Each file covers an area of approximately 250 km2. The main components are: * Hydrography (lakes, rivers, streams, streams, swamps, etc.). * Vegetation (forests, peatlands, nurseries, orchards, etc.). * Human constructions: * transport infrastructures (roads, bridges, airports, etc.); * buildings (roads, bridges, airports, etc.); * buildings (mobile homes, silos, greenhouses, etc.); * equipment (docks, electric power transmission lines, surface reservoirs, etc.); * equipment (docks, electrical power lines, surface reservoirs, etc.).); * designated areas (golf courses, loan banks, etc.). * The relief (the contour lines are generally ten meters equidistant and, in in some cases, they may vary between eight and twenty meters).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Topographic mapping of northern indigenous villages is available for 23 villages. It was produced by photogrammetric method, from aerial photographs taken between 2009 and 2011. The accuracy of this mapping is of the order of ±40 centimeters in planimetry. In hypsometry, it is ±50 centimeters for dimensional points and ±1 meter for level curves. This precision may vary locally. The main components are: * Hydrography (body of water, watercourse, etc.); * Communication routes and road and airport infrastructures (road, bridge, airport, etc.); * Buildings and various constructions (building, wharf, surface reservoir, etc.); * Vegetation; * Vegetation; * Vegetation; * Geomorphology; * Geomorphology; * Level curves equidistant from 2 meters; * Rated points. The following villages are available: * Akulivik; * Aupaluk; * Aupaluk; * Chisasibi; * Eastmain; * Inukjuak; * Ivujivik; * Kangiqsujuaq; * Kangiqsujuaq; * Kangirsuk; * Kangirsuk; * Kangirsuk; * Kangirsuk; * Kawawachikamach; * Kuujjuaq; * Kuujjuarapik-Whapmagoostui; * Mistissini; * Nemaska; * Ouje-Bougoumou; * Puvirnituq; * Puvirnituq; * Quaqtaq; * Salluit; * Tasiujaq; * Umiujaq; * Waskaganish; * Waskaganish; * Waswanipi; * Wemindji.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

GeoAI are buildings, hydrography, forests, and roads automatically extracted using Deep Learning models applied to a source dataset, typically aerial or satellite images. The primary aim of GeoAI is to increase Canada's availability of high-resolution foundational geospatial data for both spatial and temporal coverage. ‌ The infrastructure and expertise put in place by NRCan enables a rapid, efficient, and scalable data creation process through the use of leading-edge technology and Artificial Intelligence models. Published datasets for a given source can be revisited at a later date as more accurate models are developed and put into production. For now, only static files are available, but as the series develops, new products and services will be added.

The manmade features of the CanVec series include dams, protection structures (breakwater, dike/levees), liquid storage facilities (basin, swimming pool, etc.), tanks, buildings, delimiting structures (fence, walls, etc.), landmark features (cross, radar, crane, forts, etc.), chimneys, towers, sewage pipelines, conduit bridges, waste, leisure areas, residential areas, commercial and institutional areas and ritual cultural areas (shrine, cemeteries, etc.). The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.
