Natural Science Forum / Earth Science / Oceanography / March 2006JTides Version 4.9, recent update.
JTides is a free Java program that provides worldwide tidal predictions for over 3300 sites, and provides its results in a number of useful ways. JTides has recently managed to reacquire data sources for some United Kingdom sites after being obliged to remove all UK data several years ago at the insistence of the UK Hydrographic Authority. JTides 4.9 includes a number of bug fixes and enhancements, including the ability to create multi-year Web page datasets of particular sites, suitable for posting online or downloading to a PDA. Those who have a prior version of JTides installed should delete their JTides user directory before running the new version, to allow a database upgrade. JTides is free and multi-platform.

[quoted text clipped - 13 lines] > > http://www.arachnoid.com/JTides In April 2002, the UK Hydrographic Office ordered the removal of all UK tidal data from JTides and all other free tidal prediction programs. The fact that this is a free program, created in the public interest, has had no effect on their zeal to collect nonexistent copyright fees. The fact that this decision will decrease the safety of sailing in the UK has not swayed them in the slightest. ******* Dick heads aren't they. The Met Office is the same. So what has changed, the page you gave in the link showed there was no change in the situation. > > JTides is a free Java program that provides worldwide tidal predictions for > > over 3300 sites, and provides its results in a number of useful ways.

For details of how they view use of their copyright http://copyright.ukho.gov.uk/ For people who want free tidal information the UKHO does provide this on their own web site.http://easytide.ukho.gov.uk/EasyTide/EasyTide/index.aspx so I see their position as not being something that decreases safety.

The promulgation of available information if it is being held up, is a potential threat. You have only got to look at the report of the Hurricane Bush disaster to see that. But since the information has been worked out at the expense of tax payers it should be freely distributed to them by whatever means they need. Even if that means some johnnie foreigner getting hold of it. Personally I would publish and be damned. And if I had the web space and the know how, I'd offer to do so for the OP. > > "Weatherlawyer" <Weatherlawyer@hotmail.com> wrote in message > > [quoted text clipped - 13 lines] > potential threat.

It would appear that you have not looked at the links provided, UKHO makes UK tidal info available for current data ie the next 7 days available free, nor does it charge licence fees for any one else who wishes to make current data available, so there is no restriction on current data. If you want long term information you have to pay. > But since the information has been worked out at the expense of tax > payers it should be freely distributed to them by whatever means they > need. Current Government policy is that UKHO is self funding so that those who do not use the services do not pay for them, it is only services provided for other government organisations such as the RN or the Coastguard that is funded by the Govt. > Even if that means some johnnie foreigner getting hold of it. > Personally I would publish and be damned.
