Adjustment without Conflicts
Business Drivers for Accurate Maps
• Gas Leak Survey
• 811 Requests
• Network Updates
• Regulatory Compliance
• Mobile Mapping
• Utilization of external and future applications
Conflation Project
• Objectives
– Improve spatial accuracy of GIS data
– Allow user to continue to work while conflation is underway…ie no freezing of the database or work in progress
– Maintain network connectivity
– Replace & update land base used to map assets
– Opportunity to review and accept conflation areas prior to rollout in production
Adjustment Project Methodology
www.we-do-it.com
Project Initiation
adjust.IT Installation and configuration
QA/QC of adjust.IT
Installation and Configuration
Model Shift between landbases
Define Shift Models covering
areas to be adjusted
Generate shift vectors from old land base to the new land base
QA/QC of Shift Vectors
Adjustment of assets to new
landbase
Define adjustment Job Areas
covering service territory
Capture shape of existing asset information and
adjust to new land base
QA/QC of Adjustment
Result
Delivery to Production
GIS
Group adjustment Jobs into a Delivery
Propagate Jobs to top alternative tree and sub alternatives.

� New position
computed for all assets
� Changes applied
to all alternatives
� No database
