Spatial Referencing

CCRS’s Geodetic Survey Division provides the infrastructure, products and tools to permit reliable consistent georeferencing as well as high-accuracy monitoring of Earth Dynamics.

The Canadian Spatial Reference System [PDF, 204.3 kb, viewer]: The Canadian Spatial Reference System (CSRS) is the national geodetic coordinate system which serves as a reference for all mapping, charting, navigation, boundary demarcation, crustal deformation and other georeferencing needs.

Geodetic Observations for Earth Dynamics [PDF, 271.4 kb, viewer]: Geodetic Survey Division and Geological Survey of Canada (GSC) operate networks of continuous GPS/GNSS tracking stations that permit monitoring Earth Dynamics.

Gravimetry and the Geodetic Survey [PDF, 246.7 kb, viewer]: Gravimetry plays an important role in Geodesy. Ground gravity observations combined with data from space gravity missions permit the computation of an accurate Canadian Geoid Model which will be the basis for Canada’s new height system.

GPS and the Geoid [PDF, 246.7 kb, viewer]: Ellipsoidal Heights observed by GPS can be transformed to Mean-Sea-Level Heights by applying a Geoid Model. This new approach generally produces more accurate Mean-Sea-Level Heights than tying to traditional vertical benchmarks.
