1. A method comprising:
receiving, by a processor from a sensor associated with a vehicle configured to paint a lane line, a color attribute, a pattern attribute, and a location of the lane line painted on a road by the vehicle;
determining, by the processor, using the location received, whether the road has an existing lane line;
revising, in real-time, by the processor, a high-definition digital map associated with at least one autonomous vehicle by removing the existing lane line from the high-definition digital map and inserting the lane line in the high-definition digital map at the time of line painting to enable real-time updates to the high-definition digital map; and
transmitting, by the processor, instructions to an autonomy computing system of an autonomous vehicle to change to a revised high-definition digital map, wherein the autonomy computing system is configured to control operation of the autonomous vehicle to navigate according to the revised high-definition digital map.
