 Migrate Mapping of Transmission Pipeline Data From ArcView to ArcGIS Track: Pipeline Transmission Author(s): Mary Muse PG&E has used GIS to manage its more than 6,000 miles of pipeline specifications and facilities since 1993. We began by transferring all of our paper maps to CAD. From there we transferred all of our data to ArcInfo. Updates to our system were made in ArcView. The data was stored in ArcInfo covers and was becoming very unmanageable. We needed a good way to have many people editing the database at the same time. We decided to implement a versioned geodatabase in ArcGIS with ArcSDE for SQL. This process took more than 2 years. We migrated on Nov 11, 2003. The focus of this paper is to highlight our process, failures, and successes. Our GIS is used to support Engineering, Planning, risk management assessments, compliance with the new Integrity Management Rules for Pipelines, analyzing class location changes, and Underground Service Alert notifications.
