What is the APDM?

APDM is a Template

•APDM is a template for the Pipeline Industry•Can be used for Gas or Liquids•Gathering, Transmission, or Distribution Pipelines

•There is no governing organization that has officially approved it as a standard

•Concentrates on defining and documenting CORE features using the “80% Typical” rule


What is the APDM?

APDM is a Geodatabase Model

• APDM is implemented on ESRI’s Geodatabase Object-Relational Geographic Information System Model

• The APDM is a conceptual model that can be extended and implemented to suit the needs of a business

• It relies on ESRI Technology provided in the Geodatabase:• Linear Referencing (Routes and Measures)• Topology• Versioning\Archiving• Feature Datasets\Spatial References• ArcObjects


What is the APDM?

APDM in the Geodatabase• ArcMap View • ArcCatalog View


What is the APDM?

APDM provides a generic core

• Encapsulates behavior of a data and features in a pipeline system• Extends behavior to capture pipeline operator business requirements

(procedures, workflows, processes, standards, etc.)• Allows creation of unique models from a standardized core• Presents a set of core elements (tables, attributes, and relationships)

that:• Remain consistent for any APDM implementation• Ease data transfer between existing pipeline data models (PODS,

ISAT, PPDM)• Allows for development of portable APDM software applications by

third party vendors• Promotes Interoperability!


What is the APDM?

APDM describes a pipeline by defining…

• Core Elements (centerline, activities, documents)• Stationing and Station Equations (linear referencing, station series, control points, alternate reference measures)

• Centerline Editing and Re-routing (Routes, Measures and Events)

• Coincident Geometry (Topology, Relationships between Parent & Child Features)

• Hierarchy (Lineloops, Subsystems, Activities)• Auditing (Inline History, Activities, Archiving)

What is the APDM?

APDM defines behavior using Abstract Classes• Abstract classes are the templates from which behavior (defined as

attributes in the class and relationships to other classes) are passed down to concrete feature/object classes in the APDM Geodatabase

• Control point inherit behavior from the CenterlinePoint Abstract Class

• Elbows, Valves, and Flanges inherit behavior from the OnlinePointFacility Abstract Class

• Structures inherit behavior from the OfflinePoint Abstract Class• Abstract class defines a specific set of behavior for a specific set of

features particularly for edit operations:• Control points will act this way when edited• Elbows, Valves and Flanges will act this way when the centerline

they are located on is edited• Structures located within 660 feet of the centerline will act this way

when the centerline is edited

What is the APDM?

APDM Design Rationale

• Core Features and Abstract Classes allow for customized and individualized implementations with a standard ‘core’ for flexibility and interoperability

• Core features and Abstract Classes allow APDM Technical Committee to concentrate on capturing and defining behavior of pipeline features rather than rigorous definition of the feature attributes themselves

• APDM was designed to be implemented and maintained in ESRI Geodatabase without the need for custom application code

• Location of features can be represented in Feature Classes (as geometric features) or in Object Classes (used as Event Tables)

• Features can be located on or along a pipeline by either/or both absolute positioning (Coordinates) and/or linear referencing (Route/Measure)

• A combination of feature classes and event tables is allowed within a single APDM Geodatabase.
