Geodetic Reference Systems

News: CGVD2013 is now available!

Natural Resources Canada has released the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the new reference standard for heights across Canada. This new height reference system is replacing the Canadian Geodetic Vertical Datum of 1928 (CGVD28), which was adopted officially by an Order in Council in 1935. Read more

Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis. Applications include surveying, mapping, navigation, remote sensing and mineral exploration amongst others. At the national level, NRCan maintains the Canadian Spatial Reference System (CSRS), through the use of the North American Datum of 1983 (NAD83CSRS), which is the adopted standard in Canada.

This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. One of the most popular services is the online CSRS-PPP service, which provides centimetre-accuracy positioning in either NAD83(CSRS) or ITRF using GNSS technologies.
