IntroductionIntroduction

Pipeline systems present unique data

management challenges Long thin corridors of data spanning jurisdictional boundaries

Massive volumes of data

Increased regulatory requirements (Sarbanes-Oxley)

Disparate data sources

Geographic Information Systems GIS provides solutions to data integration, visualization, data

management, systems integration

What is GIS DataManagement?What is GIS DataManagement?

Pipeline GIS data management represents a set of

technologies, organization and processes that revolvearound creating and managing geographic-style

mapping data for the purposes of supporting the

business objectives of a pipeline operating company.

Technology hardware & software systems

Organization people and business Processes requirements and work flow

OrganizationOrganization

Objectives and organization structure of the

business People, departments, hierarchy

Business requirements financial, regulatory, operational

Used to define the requirements of the GIS What should the system be and what data should it hold?

Who should it serve?

Why should it be built?

How should it integrate with the existing business?

When should it happen?

ProcessesProcesses

Daily processes? How is the data collected and maintained?

Why is the data required?

Who is collecting and maintaining the data?

When is the data required? Where is the data stored? (Data Models, Databases)

Tangible business benefits? What applications are required by the business?

What applications must utilize the data?

What results is the data going to provide?

TechnologyTechnology

Secure and transactional multi-user editing

Integrated geographic features

Archiving, auditing, and retrieval

Real-time access to the latest information Data structure and data models

Enabling technologies

Multi-User EditingMulti-User Editing

Data creation and maintenance costs money

GIS data management system support Data that is secured yet accessible to many different kinds of

users

Security involves

Distinct transactions

Defined user permissions and roles

Features/Rows are managed as objects

Single data store for both geometry and attributes


9/16

Integrated FeaturesIntegrated Features

GIS data management systems support Features are managed as a single object

Geometry and attributes describe the feature

Located in a single table structure not in disparate tables

or systems

Creation, retrieval, update and deletion of feature occurs

in single operation

Features are presented in different views

Map view

Attribute view

Behavioral view


10/16

ArchivingArchiving

GIS data management systems support Data storage for

Retrieval for regulatory audits

Retrieval for annual regulatory reporting

Retrieval for integrity management planning Data management system preserves

History of the pipeline both location and state

Events and activities that influence a feature

Changes in the state, structure and operational status

Access and IntegrationAccess and Integration

GIS Data management system supports Access to the data using a variety of industry standard tools

A variety of users with a variety of skill levels

Ad hoc and pre-defined queries

Provides easy access to the latest data Provides an architecture

That incorporates industry standard technologies

For integration with other systems That is open and flexible that can be easily expanded

That is not proprietary or closed


12/16

Data Structure-ModelsData Structure-Models

GIS data management systems support Absolute positioning of spatial features

Relative position of spatial features (Linear Referencing)

Storage and location of features using both positioning

methods

Utilization of industry standard pipeline data models

Documentation of the structure, content and behavior of

these data models

Enabling TechnologiesEnabling Technologies

GIS data management systems support

And integrate with enabling technologies such as GPS,

Hand-held field collection devices,

Wireless devices,

Database replication,

Remote data access,

Integrity management systems,

Cathodic protection systems,

Document management systems,

Engineering design systems,

Right-of-way management systems,

Client information management systems,

Network flow analysis systems,

Real-time monitoring systems (SCADA)

Other systems by provide technology hooks used for integration


14/16

Why is GIS DataManagement Important?Why is GIS DataManagement Important?

Exponential increases in the amount of data

collected and required by a pipeline operation

Rising maintenance and integration costs

Increased regulatory requirements

Increased user demands for information

If a picture is worth a thousand words, a map is worth a million

The Benefits of GISData ManagementThe Benefits of GISData Management

Easy access to data by any kind of user

Re-combination of data to provide more or

better data

Integration of seemingly disparate data into a

unified data model/structure

Create automated processes for spatial

analysis and improve business processes

Integration of disparate systems with the GIS

to provide (start at the top of this slide)

ConclusionsConclusions

GIS data management system can form an

integral part of the enterprise

Implementing such systems requires careful

planning that involves understanding the

Technological, Organizational and Proceduralrequirements of the system

Provides meaningful access to GIS data for

all users in the enterprise

Increases productivity and capability
