6. GIS in
 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.

7. 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.

10. Outage Database Update Process
BENEFIT:
 FME supports direct output to Excel file, and no
extra conversion needs to be done.

11. 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.
