Remarks
Hybrid geoid model valid at epoch 1997.0. Provisional grid derived through NAD83(CSRS98) (= NAD83(CSRS)v2) used HT1 software. This grid is an update derived through NAD83(CSRS)v3. It is used in HT2 software. It is also used as CT to CGVD28(v2.0) height.
Frequently Asked Questions
What is the accuracy of the NAD83(CSRS)v2 to CGVD28 height transformation?
This transformation (EPSG:9984) has an accuracy of 0.05m using the Geographic3D to GravityRelatedHeight (NRCan byn) method. Area of use: Canada - CGVD28.
