Automatic roadway stack calibration based on geographic information system secondary development technique

Roadway stack plays an indispensable role in the whole cycle of road exploration design, construction and maintenance management. However, due to human factors, the settlement error of road 100-meter piles between the actual station and the designed station is unavoidable, which has significant influences on the subsequent road maintenance management. In this paper, in order to calibrate this type of error, a calibration strategy and the Geographic Information System (GIS) secondary development is realized, which combines ArcGIS model builder with Python script. Finally, an automatic calibration tool is developed. The automatic batching processing method for the roadway stack calibration improves the accuracy and efficiency of the vehicle-based pavement maintenance.
