Life before FME…Contractors and Code In the last 8 years, ENMAX’s Geomatics group has

been using FME primarily for mass data conversions between CAD and ArcGIS 9.2 formats.

Recently, FME has been applied in many other projects as a powerful and dynamic ETL tool in our organization.

Outage Database Update Process

ENMAX Outages is a custom application that produces internal notifications regarding outages in our distribution area.

FME process updated the Excel spreadsheet file that is used as input for ENMAX Outages. The update frequency is monthly.

Site to Transformer Automation Process

Spatial Electric Service data shows how electric services are distributed from transformer to parcels on map view (Spider Diagram).

The Site to Transformer process turns the Electric Service information to spatial Electric Service data.

This process used to be done by GIS drafters manually.
