Abstract: A system for producing, from data affiliated with images of a location, a digital map can include a processor and a memory. The memory can store a productions module and a communications module. The production module can include instructions that cause the processor to produce, from the data affiliated with the images of the location, the digital map. The data, for an image, can exclude pixel color data, but can include information about: (1) a pose of a camera that produced the image and (2) one or more of a position of a point on: (a) a lane boundary of a lane of a road in the image, (b) a road boundary of the road, or (c) a landmark in the image. The communications module can include instructions that cause the processor to transmit the digital map to a vehicle to be used to control a movement of the vehicle.

Abstract: System, methods, and other embodiments described herein relate to implementing a mapping management system. In one embodiment, a method includes receiving trace data; processing the trace data to provide a group of passes within a lane segment; determining error measurements for the group of passes within the lane segment; receiving a criterion; and determining an estimated number of passes to satisfy the criterion based on the error measurements.
