This could be a subject of the Baccalaureate in Economic Sciences, and although I never took this exam (because of post-68 incompatibility and Cancerism chronic) The subject seems to me sufficiently imminent and serious to attempt to deal with it, from my modest point of view. Read more …

Electronic charts : scales and overscale [Update]
A recent email exchange with a Mediterranean user drew my attention to a specific aspect of electronic charting : zoom limitation of a chart. ENC vector charts (¹) are classified in 6 categories depending scale : smallest scales less than 1:1.500.000 for global views to largest scale up to 1:4.000 for harbours and anchorages. (²).
Marine charts international classification
In most cases, ENC S-57 (¹) official charts the most detailed have a scale about 1:4000, thus 1 cm on the chart (screen view) represent 40 meters on the ground. With paper chart, the only way to get more details is… to use a a magnifying glass, that provides, as we know, in no case more accuracy. But it is quite otherwise for electronics charts.

Charting, the game of 7 errors
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.

SEAiq professional navigation on iPad
A 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.

Charting compared, a mixed result
Three 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.
