Working with Geometric Networks for Utilities

Strictly by pre-registration only

What is this course about?

Utility companies’ users can learn how to inspect the logical consistency of a network and verifying connectivity between two points.

Water utilities’ users can determine which valves to shut off when a pipe burst.

Environmental monitoring stations can hone in on a source of pollution in streams.

Electric companies’ users can check which part of the network is disconnected and use that information to figure out how to reconnect it or how to discover an electrical short circuit.

Electric utility companies can use the phone calls of customers experiencing an outage to locate suspect transformers or downed lines.

This course is for: Managers or Engineers who want to examine the direction of flow along edges, and ArcGIS who want to use the flow directions to perform flow-specific network analyses.

Safety measures for training courses

While courses in our training facility have resumed, we want to assure you that the wellbeing of our trainees and staff remains Esri Singapore’s highest priority.

As the COVID-19 situation continues to develop, strict safety measures and guidelines as recommended by the Ministry of Health are being adhered to for all training conducted.

All computer equipment and desks are disinfected before class commences and during the lunch break, while seats are placed and marked at least 1-metre apart, in accordance with official Safe Distance Measures.

Masks are mandatory throughout training, and alcohol hand sanitisers and anti-bacterial wet wipes will be available.

Your temperature will be taken before commencement. For your safety, you will be asked to return home and see a doc if your temperature exceeds 37.5deg.

An isolation room has been prepared for trainees to rest in if they are feeling unwell and awaiting transportation.

What skills will I learn?

After completing this course, you will be able to:

  • Calculate the shortest path between two points
  • Find all connected or disconnected network elements
  • Find loops or circuits in the network
  • Determine flow direction of edges when sources or sinks are set
  • Trace network elements upstream or downstream from a point
  • Calculate the shortest path upstream from one point to another
  • Find all network elements upstream from many points and determine which elements are common to them all
