Highway Elevation Data Smoothing Using Local Enhancement Mechanism and Butterworth Filter
2017
International Journal of Innovative Computing, Information and Control
Highway elevation is an important factor for performing quantitative and qualitative analysis of traffic safety, traffic operation and management. Google Earth provides public accessible highway elevation data which is deemed as a credible elevation source by many researchers and transportation practitioners. However, the raw elevation dataset, extracted from Google Earth, shows multiple types of outliers. Hence, we presented a local enhancement mechanism integrated with Butterworth filter to
