Quebec Topo Map 1:20 000 – 11M01-200-202

Quebec Topo Map 1:20 000 constitute the official cartographic base of the Government of Quebec.

They cover almost the entire 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 approximately two meters for dimensioned points and approximately five meters for contour lines.

Each file covers an area of ​​approximately 250 km2.

The main components are:

• Hydrography (lakes, rivers, streams, swamps, etc.).
• Vegetation (forests, peat bogs, nurseries, orchards, etc.).
• Man’s constructions:
  • transport infrastructure (roads, bridges, airports, etc.);
  • buildings (mobile homes, silos, greenhouses, etc.);
  • equipment (docks, electrical power transmission lines, surface tanks, etc.);
• designated areas (golf courses, borrow pits, etc.).
• The relief (the contour lines are generally at an equidistance of ten meters and, in some cases, they can vary between eight and twenty meters).
