CherSoft developed the Digital List of Lights for the United Kingdom Hydrographic Office.
The Admiralty Digital List of Lights is a digital version of the popular Admiralty List of Lights and has been specifically designed to reduce the time and effort spent on manual corrections of paper publications.
A chart-based interface and comprehensive search facilities make the Admiralty Digital List of Lights easy to use, and the publication can be kept completely up to date for safety-critical information through the use of a free automated update service.
