Over the last ten years, the Department has implemented
a highly accurate geodetic network comprising 1,900 points covering
the southern portion of Québec. In addition, the 18 permanent GPS reference stations that have been deployed offer modern positioning technology. 17 of the stations provide real-time centimetric positioning capabilities using cellular telephony. Furthermore, calibration bases were erected in Québec's main areas
in order to offer users the possibility of checking and calibrating electronic
distance measurement (EDM) equipment. The Québec and Montréal GPS validation
networks are used to validate GPS survey systems.
The Department has also
established a base geodetic network that comprises 57,000 planimetric
network points and 22,000 leveling network points. This infrastructure,
which consists of the geodetic reference system and the altimetric reference
system, is for customers involved in geomatic-related activities,
such as mapping, topography, and spatially referenced information systems.
In addition, the Department has
more than 35 years of experience in geodetics. Based on its
expertise in establishing the geodetic networks using GPS, the Department
excels in standardizing, planning, implementing, integrating, and
managing all of Québec's networks. The Department
distinguishes itself in work organization and supervision, cost
assessment, data processing and quality control, conservation, and access
to results. Its know-how with respect to planning GPS surveys
makes the Department a preferred partner
for a great many departments, municipalities, and organizations in Québec.
Moreover, many surveying firms in the province also have internationally
recognized experience in GPS surveying.
Areas of Application
GPS technology offers a nearly unlimited
range of services. Indeed, the usefulness of this technology has
already been demonstrated, particularly in:
- Aerial and marine navigation;
- Positioning objects and phenomena;
- Geodetic and aerial surveys;
- Navigation and vehicle monitoring;
- Managing natural resources and precision agriculture;
- Outdoor activities.
The Department has acquired
sound expertise related to geodetic infrastructure and GPS technology.
This recognized know-how can be shared with any government interested
in optimally developing its territory.
