Introduction to Smallworld GNM for Utilities

Smallworld Geo Network Management (GNM) has been a cornerstone technology for utility companies worldwide for over three decades. In this article, we explore what makes Smallworld GNM unique and why it remains the platform of choice for many utilities.

What is Smallworld GNM?

Smallworld GNM is a Geographic Information System specifically designed for managing large-scale network infrastructure. Originally developed by Smallworld Systems in the UK, it is now part of GE Vernova’s GridOS platform.

Key Features

• Network Management: Purpose-built for managing complex utility networks
• Scalability: Handles millions of network assets efficiently
• Magik Programming: Powerful object-oriented language for customisation
• Integration Capabilities: Connects with SCADA, OMS, and other enterprise systems

Why Utilities Choose Smallworld GNM

Unlike general-purpose GIS platforms, Smallworld GNM was designed from the ground up for network-centric industries. This specialisation means better performance, more relevant features, and lower total cost of ownership for utilities.

The Version Managed Datastore (VMDS) allows multiple engineers to work on network designs concurrently without corrupting the master record. The built-in network connectivity model ensures that electrical, gas, water, and fibre topology is always represented correctly — something bolted-on GIS platforms struggle to match.
