1. A method comprising:
applying, to one or more neural networks, sensor data representative of one or more sensor representations that correspond to at least a navigable surface region of an intersection that is located within an environment;
processing the sensor data by the one or more neural networks to generate output data representative of distance information indicating one or more distances to the navigable surface region that is within edges of the intersection;
determining, based at least on the distance information, a location of the intersection within the environment; and
causing a vehicle to perform one or more operations based at least on the location of the intersection.
