The GeoInformation Group takes Scotia Gas Networks to New Heights
Expert spatial data consultancy service enhances pipeline safety programme
The GeoInformation® Group, publishers of Cities Revealed aerial photography announce today that it has completed an extensive consultancy project for the UK’s second largest gas supplier, Scotia Gas Networks (SGN). SGN operates two of the largest regional gas networks - Scotland Gas Networks plc and Southern Gas Networks plc, it covers over 50% of the landmass and its first priority is to provide a safe and reliable supply of natural gas to all its 5.7 million customers.
In order to comply with Pipelines Safety Regulations, SGN has a requirement to locate and identify high-rise buildings of five storeys and more so that it can carry out a regime of regular survey and inspection of those buildings containing internal metallic gas pipes. The GeoInformation Group was tasked with the project; using heights databases combined with fieldwork to successfully identify all high-rise buildings for the entire SGN network area. From the hundreds of thousands of buildings analysed, SGN was supplied with a final database of over 14 000 addresses. SGN will be cross-referencing the address data against customer records to schedule surveys from 2008 onwards.
Tony Hughes, Network Support Manager at SGN, commented, “By outsourcing this project SGN are benefiting from highly accurate and cost-effective results. The alternative would have been a very costly, time consuming and much less accurate street-by-street survey of the entire gas network. The results provided by The GeoInformation Group enable us to run a more efficient maintenance programme and offer our customers the assurance of a safe gas supply.”
The height data used in this project was derived from multiple sources including: LiDAR, Intermap and photogrammetry, and verified vertical and oblique aerial imagery. By using a range of data sources and field verification the accuracy levels are highly consistent.
The GeoInformation Group provides a wide range of data services, including sourcing and analysis, scanning, data engineering, in addition to bespoke consultancy and training solutions. It also publishes the Cities Revealed product portfolio, including Building Heights, a highly accurate database and can be utilised in a wide range of height sensitive applications, from urban development to telecommunications planning. This valuable information source can also be used, in conjunction with the vector base mapping, to create a precise representation of the three-dimensional built environment.

Each month we select a hot topic and a leading figure in the industry to write about it.HAVE WE REALLY LEARNT THE LESSONS FROM LAST YEAR’S FLOODS?
Flooding costs associated with extreme weather, both financial and emotional, have increased considerably over the last decade, and experts have predicted this trend is set to continue.
Paul Livett, Chairman of GroundSure looks into how increasing the use of flood risk information in property transactions can help to ensure both residential and commercial transactions are conducted on a truly informed basis, with buyers being made aware of environmental risks prior to purchase.
Over 2.2 million homes and small businesses in the UK are located in areas considered at risk of flooding, and the Association of British Insurers (ABI) has said that 570,000 of these face a high risk of flooding. The floods in June and July last year left approximately 48,000 households… More…
