System and method for mapping through inferences of observed objects

System, methods, and other embodiments described herein relate to improving mapping of a surrounding environment by a mapping vehicle. In one embodiment, a method includes identifying dynamic objects within the surrounding environment that are proximate to the mapping vehicle from sensor data of at least one sensor of the mapping vehicle. The dynamic objects are trackable objects that are moving within the surrounding environment. The method includes generating paths of the dynamic objects through the surrounding environment relative to the mapping vehicle according to separate observations of the dynamic objects embodied within the sensor data. The method includes producing a map of the surrounding environment from the paths.
