Optimizing APDM Model to Increase Location Accuracy of Pipeline

Pipeline integrity database established based on APDM model provides data support for different analysis assessmeni results of integrity management.However, certain errors often exist between special geography locations and actual survey results in conventional management manner.Based on analyzing different errors.measures taken from the point of improving survey mode and optimizing APDM model so as to increase locating data's accuracy are put forward.These measures can solve the problem existed in conventional techniques and provide reliable data for integrity management of pipelines.
