What to expect: Your coordinates will change

The magnitude of change in your coordinates will vary based on the datum you are currently using, your geographic location, and the epoch of the new coordinates. View the maps below to see the approximate horizontal and height changes when the new NSRS TRFs are adopted and coordinates refer to reference epoch 2020.00.
