Major Utilities contract!

Cad-Capture (Blackburn, UK) has been awarded the Positional Accuracy Improvement (PAI) data services contract for United Utilities, possibly the largest PAI contract to date.

The major six-figure deal was won against stiff competition due to Cad-Capture's technical and commercial strengths and experience in this field.

Simon Watts, Managing Director of Cad-Capture said: "Once again Cad-Capture has the opportunity to work with United Utilities in a partnership that has been established over the past 20 years. Winning this project is a tremendous achievement and a testament to the quality of service provided by Cad-Capture."

About PAI

Current OS digital mapping originates from 1950's mapping and the conversion resulted in poor absolute accuracy in rural areas.

Global Positioning Systems technology (GPS) and geographical information systems (GIS) have moved ahead of map data and greater accuracy was necessary.

From 2001 to 2006 Ordnance Survey (OS) has undertaken a national programme of 'Positional Accuracy Improvement' (PAI) for rural digital mapping and this has introduced a requirement for government agencies, utilities and local authorities, etc. to realign any digital assets or features referenced to OS mapping if the revised PAI mapping is to be loaded to the GIS system.

PAI mainly impacts the 1:2500 scale OS 'Land-Line' mapping and has created varying and inconsistent shift to map features typically of 1 to 3m but as much as 13m. The latest OS mapping product 'MasterMap' will only hold PAI map versions for rural areas and it is the OS intention for 'MasterMap' to replace the existing 'Land-Line' mapping product in 2008.
