Claim 14:
15. A method of transforming a position of a location of interest from a first reference frame to a second reference frame, wherein at least one of the first and second reference frames is a reference frame corresponding to a coordinate system of a digital map covering a geographic region including the location of interest, wherein the position of the location of interest with respect to said at least one of the first and second reference frames is a position with respect to the digital map, the method comprising:
obtaining data indicative of the position of the location of interest with respect to the first reference frame;
obtaining displacement map data comprising, for each of one or more locations, data indicative of a change in a position of each of the one or more locations with respect to the Earth's surface occurring over time as a result of crustal dynamics;
determining, based on the data indicative of the position of the location of interest with respect to the first reference frame and the displacement map data, data indicative of the position of the location of interest with respect to the second reference frame, the determining including:
transforming the position of the location of interest with respect to the first reference frame to the position of the location of interest with respect to the second reference frame, the transforming including using the displacement map data to adjust a position of the location of interest when transforming the position of the location of interest from the first reference frame to the second reference frame to compensate for at least one change in Earth's surface occurring as a result of crustal dynamics;
performing, based at least in part on the data indicative of the position of the location of interest with respect to the second reference frame, one or more navigation-related operations for or associated with a vehicle.
