  "textContent": "The present disclosure relates to a method performed by a digital map enhancement system (1) for improving accuracy of pre-stored digital map data (311) of a digital map (31) adapted to be utilized by a vehicle (2). The digital map enhancement system determines (1001) a current position (21) of the vehicle (2), and identifies (1002), in the pre-stored digital map data, a mapped digital landmark (3111) representing a stationary landmark (4) predicted to be in the vicinity of the current position of the vehicle, which mapped digital landmark comprises a pre-stored position (31111) of the stationary landmark. The digital map enhancement system furthermore detects (1003) the stationary landmark by means of one or more sensor devices (5) on-board the vehicle, which one or more sensor devices are adapted for observing the surroundings of the vehicle, and determines (1004) a detected position (41) of the stationary landmark based on the current position of the vehicle and the detection of the stationary landmark. Moreover, the digital map enhancement system updates (1007) the pre-stored position comprised in the mapped digital landmark, with the detected position of the stationary landmark. The disclosure also relates to a digital map enhancement system in accordance with the foregoing, and a vehicle and/or a mobile device (9) comprising at least a portion of the digital map enhancement system.",
