ISYS was formed in 1989 as a software and computer consultancy company. In 1996 it launched the first ever outdoor software on CD, called 'The Munros through Windows'. In 2003 they became a partner with Ordnance Survey, and ISYS programs were updated to include Ordnance Survey mapping. Over the last nine years ISYS has expanded its outdoor software range to cover all hills in the British Isles.
