Water companies approach Infoterra as demand for accurate data to improve flood prediction continues
March 28, 2007 -- Infoterra Ltd, a leader in the provision of geospatial products and services, has supplied regional water and sewage treatment provider Wessex Water with lidar* height data of the urban landscape throughout the South West of England.
This precise terrain height data, captured at 1m horizontal intervals, will provide Wessex Water with a reliable dataset to enable accurate flood modelling and risk analysis. The lidar data provided will significantly improve modelling, planning and investigation of both overground and underground water flow. It will be used to generate a visual representation allowing experts to view and calculate the complete impact of a flood event.
Dave Searby, technical manager at Wessex Water said: “Hydrological consultants, Richard Allitt Associates are using Infoterra’s accurate height data to improve our flood prediction and definition of risk.”
Dr Andy Wells, head of sales at Infoterra Ltd said: “Lidar data is the most accurate, most detailed and most reliable way for water companies to improve modelling. By using detailed terrain height data they can verify records of man hole cover heights to improve hydrological modelling and calculate the likely water flow following a flood.”

About Wessex Water
Wessex Water is the regional water and sewage treatment business serving an area of the south west of England, covering 10,000 square kilometres including Dorset, Somerset, Bristol, most of Wiltshire and parts of Gloucestershire and Hampshire.
*Lidar (laserscanning) technology operates on a similar principle as radar, where a series of laser pulses are transmitted from an aircraft and are then reflected back giving detailed information of individual height points. Infoterra has extensive commercial experience in undertaking lidar surveys of flood plain regions, urban areas and coastal zones. By delivering lidar height data with a vertical accuracy of +/- 15cm, surveyors and planners gain valuable information.
