Application Level Logic

New Technology

• ALRPArcGIS Location Referencing for Pipeline

• UPDMUtility and Pipeline Data Model

What is ALRP

• Adds Linear ReferencingCapabilities to the Geodatabase

• Is a mixture of linear referencing enabled features combined with Esri software (extensions and GP tools)

• Software is being developed for the ArcGIS Pro platform

+ footage

What is UPDM

• Template Data Model for Pipelines

• Capable of supporting both stationed and non-stationed pipelines

• Utilized a Geometric Network and ALRP together

• Targeted at vertically integrated utilities - (Distribution and Transmission)

CenterlinesequenceKey table for M-N relationship between Centerline and Route.

• Two routes

• 4 Calibration points

• 3 centerlines

The two routes above are derived from three centerline lines

Multiple Location Referencing Modescan be utilized simultaneously

Vision

Incorporate ALRP objects into the core of PODS and align Relational Model attributes with new model
