1. A vehicle computing system, comprising:
a memory storing computer instructions; and
a processor communicatively coupled with the memory to execute the instructions, capable of:
receiving a digital representation of a road that includes one or more lane representations;
processing a first segment of the digital representation of the road and determining that no altitude discontinuity exists in the first segment;
using the first segment of the digital representation of the road for vehicle operation;
processing at least a second segment of the digital representation of the road and determining that an altitude discontinuity exists in the second segment;
processing the at least second segment of the digital representation of the road to substantially remove the altitude discontinuity and to generate a modified second segment of the digital representation of the road; and
using the modified second segment of the digital representation of the road for vehicle operation.
