The project will enable the energy distributor to carry out detailed and rapid site surveys from desktop computers to assess the impact of damage to the powerline network and to manage maintenance operations.
It will also reduce E.ON's need to conduct site visits, particularly in off-road locations.
The project will start in Leicestershire, with Infoterra using high-resolution GeoPerspectives stereo imagery to map the precise powerline pole locations, pole heights, span lengths and the exact network length.
"We are constantly looking for innovative ways to improve our internal business processes and the strategic management of our network," said Robert Ferris, innovation manager for E.ON Central Networks.
"Thanks to the high level of detail in Infoterra's mapping system we will have invaluable information for our ongoing asset management."
