TGT e-Data modules

TGT e-Data is available to buy as individual modules on annual subscription or in easy to buy packages. A summary of the modules is provided below.

British Admiralty Notice to Mariners

TGT e-Data provides the complete UKHO NTM Sections I to VI together with Tracings and Blocks to make chart correction as fast and efficient as possible. All Sailing Directions, List of Lights and Fog Signals and Radio Signals publications have separate correction logs to enable the crew to select and print the corrections only for the publications they need. Read more about how the service works.

JHA NTMs and Tracings

TGT e-Data includes Japanese (JP) NTMs and Tracings. JP graphic files are traditionally very large. TGT e-Data compression techniques significantly reduce the sizes of JP files sent to the ship and offers considerable cost savings on data communication costs, whilst ensuring JP corrections are immediately available onboard.

US NTMs and Tracings

US NTMs and Tracings NTMs and Tracings for all charts issued by NOAA are available through TGT e-Data. All US tracings are digitally produced specially for TGT e-Data software by our in-house specialists. The file size of our digitally produced tracings are much smaller than traditional PDF tracings to minimize data communication costs and make it possible for ships to cost effectively and to receive all the corrections they need for US charts via e-mail without the need to wait for the weekly CD.
