  1. Introduction to the ArcGIS Pipeline Data Model (APDM)Version 4.0 Peter Veenstra ESRI Petroleum User Group Conference - 2006

  2. Introduction Presentation about … • Introduction to the APDM • Overview of APDM Version 4.0

  3. ArcGIS Pipeline Data Model (APDM) Who: Industry consortium of ESRI, pipeline vendors and operators PUG  PIG  Steering Committee, Technical Committee What:Geodatabase model for transmission pipelines When: PUG, ESRI User Conference, GITA Oil & Gas Why: Passionate about ESRI technology

  4. Overview of the APDM • ESRI Geodatabase model for … • gas and/or liquids, onshore/offshore, gathering, transmission, or distribution pipeline systems • Focused on pipelines that use stationed position AND XY coordinates to locate positions of features on or along the pipeline • APDM  ESRI Object Model Template to handle … • multiple forms of linear referencing • ESRI route and measure technology • hierarchical/geographical organization of pipeline features • Feature behavior during centerline editing operations • Links to external systems – ERP, Document Management, Work Order MS • Core Feature\Object Classes • Abstract Classes

  5. Overview of the Model • APDM is the intellectual property of ESRI • Managed in trust by the Pipe Interest Group (Petroleum User Group) • Version 1.0 Build the model • Focus on the technology, the core and conceptual classes in the model. • Version 2.0 – 3.0 Link to the Enterprise • Refine the conceptual model, expand the core • Activities, External Documents, OwnerOperator, EventID • Version 4.0 Metadata • Data content • Schema Description and Management • Object behavior • Best Practices  Interoperability

  6. APDM Steering and Technical Committees • APDM 4.0 Steering Committee ·Robert Brook, New Century Software, ·Chris Elmer, Sempra Utilities, ·Greg McCool, Enbridge Energy Company, ·David Nemeth, Panhandle Energy, ·Debra Rohrer, Columbia Gas, ·Mark Warner, Questar Pipeline, ·Edward Wiegele, GE Energy, ·Craig Wilder (Chairperson), El Paso Corporation, ·Chad Zamarin, Colonial Gas, ·Andrew Zolnai, ESRI, ·David Frye, ESRI, • APDM 4.0 Technical Committee • ·John Alsup, ESRI, • · Jannette Jensen, Questar Gas Company (Secretary), • ·Theo Lawrence, Great Lakes Gas Transmission, • ·Todd Murphy, Panhandle Energy Corporation, • ·Buddy Nagel, El Paso Corporation, • ·Jeff Puuri, Advantica, • ·Fred Spickler, Photoscience Inc, • ·Tracy Thorleifson, Eagle Information Mapping, • ·Peter Veenstra, GE Energy (Chairperson),

  7. APDM Version 4.0 • Abstract Classes (Core Attributes and Relationships) • Centerline Objects, Facility Objects, Online/Offline Objects • Response to editing the centerline • Auditing feature/object edits • Core Classes • ControlPoint, StationSeries, AltRefMeasure, Lineloop, Subsystem, SubsystemHierarchy, LineloopHierarchy, Product, OwnerOperator, SubsystemRange, Site, Activity, ActivityHierarchy, ExternalDocument • Metadata Classes • Formal definition to describe behavior of reference modes • Units, Basis, Type • Listing and APDM categorization of classes within geodatabase • Each class in the APDM will inherit from one of the APDM Abstract Classes • Online Locations for Offline Features • Listing of offline/online class pairs • Listing of calculation methods for determining derivation of online locations • Inline History and Auditing • Facilities and Non-Geometric representation of features

  8. ArcGIS Pipeline Data Model (APDM) • APDM Logical Model Poster – shows abstract classes, metadata classes, core classes and example concrete classes

  9. Abstract Classes

  10. Abstract Classes • Object based abstract classes showing centerline objects, facility objects and non-facility objects

  11. Abstract Classes • Feature based abstract classes showing centerline objects, online/offline objects, facility objects and ‘online’ location objects

  12. Abstract Classes- Inheritance • Example showing how a ‘concrete’ class is derived via inheritance from the APDM abstract classes

  13. Core Classes • Represent the core classes within the model that must be implemented • These classes represent critical parts of a pipeline reflecting centerline editing and integration with other enterprise systems • ControlPoint – known points of XY and station value location for a given reference mode • StationSeries – a route feature built from control point for a given reference mode • AltRefMeasure – stores alternate reference mode information for online features • Lineloop – a series of connected station series forming a ‘line’ or ‘route’ • LineloopHierarchy – ability to categorize lineloops into logical groupings • Subsystem – an area or zone along the pipeline used to break it up into logical regions • SubsystemHierarchy – ability to categorize subsystems into logical groupings • SubsystemRange – the ‘online’ location of a subsystem along the centerline • Product – the product transported by the pipeline • OwnerOperator – owner and operator information for the assets of a pipeline • Site – any site boundary on or along the pipeline • Activity – things that ‘happen’ during the operation and maintenance of a pipeline • ActivityHierarchy – ability to categorize activities into logical groupings • ExternalDocument – reports, regulatory and source documents that specifiy or document assets and events on or along the pipeline

  14. Metadata Classes • Describes the internal structure of the model for validation and verification

  15. Implementing APDM • APDM is built for the geodatabase • It is an object model • It describes feature editing behavior • It provides meta-data or meta-models that can be integrated with other data models • APDM Core  APDM Tables  Add/modify classes and attributes • APDM Core  PODS Business/Feature/Event Tables  Add/modify classes and attributes • APDM Core  ISAT Business/Feature/Event Tables  Add/modify classes and attributes • APDM Core  Any pipeline data model business tables …  Add /modify classes and attributes • Implement APDM Abstract Tables and Core Tables

  16. Compliance and Interoperability • The purpose of APDM is to capture the ‘behavior’ of pipeline events, features and objects within an geodatabase object model • The purpose of APDM 4.0 abstract, metadata and core classes is to provide a standard for judging APDM compliance to allow true interoperability between vendor applications and data models • Interoperability could be assessed by development of a standard set of editing, reporting and analysis applications that could be applied to any APDM geodatabase

  17. Current Status of the APDM • Yearly cycle • Accrual of ideas and feedback – ESRI UC  Gita Oil & Gas (Summer to Fall) • Technical Committee develop new aspects of model (Fall through Winter  ESRI PUG) • Model Release (Spring  ESRI UC) • Planned Events • APDM Pre-Conference Workshop – Saturday, August 12th • • Scheduled release of proposed changes (V4.0) • Logical Model Poster, Physical Model UML (Visio 2002 format) available from • White paper will be released in sections over the next 2-3 weeks for review up until 05/2006

  18. Contact Information • Online Resources (APDM) • • APDM Model and white paper, UML, XMI, logical model •\datamodels • APDM Technical and Steering Committees • Andrew Zolnai • Craig Wilder • Peter Veenstra
