Smallworld GIS at Stadtwerke Unna –
Business benefits through standardisation

Unna, Paderborn, August 2006

In 2005, medium-sized utility company Stadtwerke Unna GmbH put a new GIS generation into effect. Starting from scratch, the old GIS “IRIS” system was replaced by a comprehensive Smallworld 4.0 solution and the entire network was digitised while the system was set up.

One key factor in the decision making process was the delivery of the standard data models and industry-specific applications Smallworld NRM (Electricity and Gas Network Resource Managers). The main objectives in the project were to achieve early system productivity and to boost the deployment by business users.

Smallworld Field & colibri

By providing a universally accepted operational concept for all users all application cases are covered. Hence, users working at their GIS work station, as well as users of the Smallworld Field mobile solution, are supplied with a nearly identical look-and-feel.

Smallworld Field was deployed in conjunction with a ruggedised pencomputer (colibri) and a Leica GPS 1200 rover. In this way, not only the viewing of maps and attribute data was put into practice but also a data round trip that allows sketching and attribute update by field engineers, including data update and capturing via GPS. A total of eight Smallworld Field clients are running on seven ruggedised tablet-PCs and on one in-house work station.

Network Calculation

Based on the acquired GIS data, the utilisation of the Smallworld Geographical Information System is extended towards further important application areas. Network operation at Stadtwerke Unna is supported by calculation programs implying GIS data. Via a standardised systems interface, the data is conveyed to the Siemens’ SINCAL calculation program, allowing thorough analyses. Moreover, Stadtwerke Unna will use Mettenmeier’s Operation Analyser for day-to-day calculations.

Integration of Street Lighting

Beside Smallworld GIS, Stadtwerke Unna deploys the software Communa-Lux for technical and operational management of street lighting, allowing for capture and specification of all technical and organisational data, repairs and maintenance, periodical energy billing and rationalisation of energy, etc. Via Oracle-interface, GIS object data like lamp numbers are displayed in Communa-Lux.
