Abstract
System, methods, and other embodiments described herein relate to associating coordinates between separate coordinate systems. In one embodiment, a method includes acquiring location coordinates of a vehicle in a surrounding environment according to sensor data from at least one sensor of the vehicle. The method includes transforming reference coordinates associated with the location coordinates into first intermediate coordinates associated with a first coordinate system that is based, at least in part, on a distorted two-dimensional map projection, and second intermediate coordinates associated with a second coordinate system that is a Cartesian coordinate system associated with a Geodetic datum. The method includes generating, using the first intermediate coordinates and the second intermediate coordinates, an estimated transform for converting between the first coordinate system and the second coordinate system. The method includes projecting one or more annotations encoded in the second coordinate system into the first coordinate system using the estimated transform.
