Charting, the game of 7 errors

Posted on5 comments

A recent Thread on the Hisse Et Oh forum, I salute by the way, I challenged the accuracy of the chart data provided on the electronic charts. The subject concerns the observation that, in some location, existing information on the Navionics Marine HD application, or on some chartplotters, are missing on Navionics charts available on the website x-traverse.com used with iNavX (and MacENC). Quote :

"So the question is : Is there a difference between the 46XG map and the Europe map or is the difference due to the software that makes the cards tick?. ”

Damned ! It seemed useful to make comparisons closing electronic charts from various sources. As far as I know particularly well geographic location used in example, since it is the approach to the port of Concarneau, near the beacon tower Le Cochon, passage I borrowed hundreds of times over the years I was working with Glenans Nautical Centre.

Posted on10 comments

SEAiqA few days before going on a long trip from Toulon to Noumea, my friend Christophe Mahé introduced me to this application which had gone completely unnoticed by me. I sincerely thank him ! As it is never too late to do well, a few discussions with the developer allowed me to install this application on my iPad with all its options. SEAiq went live on the AppStore in April 2012. Its developer, Mark Hayden, is a Californian computer engineer living a good part of his time with his family or alone around the world aboard his Super Maramu, the happy man.

SEAiq Open (¹) is the only application on iPad / iPhone for using vector charts ENC IHO official standards S-52, S-57 and S-63. With information database included in these charts, and update systems , SEAiq transforms the iPad into a real ECDIS (²) professionnal. Read more …

Marée.info is evolving its offering

You know all the good things I think about this excellent application. Unfortunately, many users did not understand that the “Free” download was intended solely to allow testing of the application before subscribing to the data.. This misunderstanding caused dissatisfaction and the developer took it into account.

Since the last update, access to all tide stations is free for the current day : Read more …

Charting compared, a mixed result

Posted on12 comments

Croisière estivale aux BaléaresThree weeks and 600 nautical miles of sailing between the mainland and the Balearic Islands have allowed me to test in live some of iPad maritime applications we have.

Warning : There is no question of making a point-by-point comparison between applications, but rather to highlight certain essential aspects of their use. On the other hand, applications used were up-to-date at the beginning of July. Developments are rapid, and updates may have occurred in August or early September that I did not have. Finally, the messaging app iNavX associated with Navionics charting available from the X-Traverse server for me is the "master-standard" marine applications. iNavX is the most complete application in terms of features to date, and Navionics charting (from the X-Traverse server, I specify) closest to the geographical reality observed by many users.

Thousands of users have known about the excellent website for several years tide.info which offers the tidal times and heights of the SHOM for all the coast stations of the Channel and the Atlantic.
