Driving Force…
• Save Time - particularly on the requests that lead to no further action.
75% of the requests were non-servable.• Store Request Location for future analysis
Three pieces to the puzzle …

CAPTURE DECISION
User enters the address
Place a pushpin on the geocoded location representing
request location
User fine tunes the location dragging & relocating the pushpin
and request a decision
Buffer the point with a distance of 150’
Intersect with the Gas Main FC
Feature Count > 0
Geocode
Send a ‘Yes’
Buffer the point with a distance of 1000’
Intersect with the Gas Main FC

Analysis
• Search – Temporal, spatial, and decision
• Export results in excel for further analysis and share
• Group email using outlook
• Measure distance and area
Analysis
• Predefine Area of Interest• Get email notification
when a predefined number of requests come from that area
• Calculate the feasibility of growth / new business
• Use this AOI as a project boundary
