Seabed mapped by app from Norfolk company

A Norfolk software company has developed an app which provides detailed information about the seabed - including the location of shipwrecks.
The app is called eChart and will be used by divers, fisherman and the offshore wind industry.
It has been produced by Norcom Technology, with the help of a £20,000 from a European innovation fund.
