This map shows the location of geodetic points in Quebec. It is available in the form of an interactive map and downloadable vector files. The location of the points is based on the approximate coordinates (± two meters).

The geodetic network consists of approximately 112,000 landmarks grouped under six themes:

* Permanent GNSS stations;

* The 3D precision network;

* The planimetric network;

* The altimeter network;

* Points presumed destroyed or damaged;

* Destroyed points.

The vector product contains the following information:

* The original number;

* The service number;

* The state of the geodesic point;

* The theme to which it belongs.

The ** [interactive map] (https://geodesie.portailcartographique.gouv.qc.ca/) ** offers more information and provides access to the associated data sheet.

# #Bases calibration for electronic rangefinder

To allow rapid and effective control of distance measuring instruments (electronic telemeter), a network of permanent calibration bases has been established in the main regions of Quebec.

Information relating to each of the bases, including inter-pillar distances, can be obtained by clicking below on the name of the municipality where the base is located:
