Abstract Road network extraction is vital to both vehicle navigation and road
planning. Existing approaches focus on mining urban trunk roads from GPS
trajectories of floating cars. However, path extraction, which plays an important role
in earthquake relief and village tour, is always ignored. Addressing this issue, we
propose a novel approach of extracting campus’ road network from walking GPS
trajectories. It consists of data preprocessing and road centerline generation. The
patrolling GPS trajectories, collected at Hunan University of Science and
Technology, were used as the experimental data. The experimental evaluation results
show that our approach is able to effectively and… More >
