Abstract
A network system evaluates candidate GPS routes with respect to map routes that are based on ground truth map data to identify defects in the ground truth map data. Defects in the ground truth map data may include inconsistencies between various attributes of the map data and the actual road network represented by the candidate GPS routes under evaluation. The network system corrects the identified feedback to ensure that the ground truth map data accurately reflects the attributes of the actual road network.
