Generating and filtering navigational maps

A system comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to:
• generate, based on sensor data captured by a first sensor of a first vehicle, an input map corresponding to a three-dimensional representation of a route traveled by the first vehicle;
• filter, based on one or more criteria, the input map to generate a filtered map, wherein to filter the input map the one or more processors are configured to automatically remove features that satisfy the one or more criteria, and wherein the features correspond to objects that are irrelevant to determining a location of a second vehicle with reference to the filtered map;
• and
• transmit the filtered map to the second vehicle, wherein the filtered map is usable by a navigation system of the second vehicle to determine a location of the second vehicle while the second vehicle is traveling along the same route.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a computer system, cause the one or more processors to perform the following:

• generating, based on sensor data captured by a first sensor of a first vehicle, an input map corresponding to a three-dimensional representation of a route traveled by the first vehicle;
• filtering, based on one or more criteria, the input map to generate a filtered map, wherein the filtering comprises automatically removing features that satisfy the one or more criteria, and wherein the features correspond to objects that are irrelevant to determining a location of a second vehicle with reference to the filtered map;
• and
• transmitting the filtered map to the second vehicle, wherein the filtered map is usable by a navigation system of the second vehicle to determine a location of the second vehicle while the second vehicle is traveling along the same route.
