The current geometric reference system adopted by most jurisdictions in Canada is the North American Datum of 1983 (NAD83). This webinar will summarize the evolution of NAD83 from the horizontal static reference frame, first adopted in 1990, to the 3D dynamic versions of NAD83(CSRS) now being used. The relationship between NAD83(CSRS) and international reference frames will be discussed, as well as the differences between the various realizations of NAD83(CSRS). The webinar will finish with some considerations for those working in NAD83(CSRS).
