Reading : 'Electronic charting' HS48 Voiles et Voiliers

Since end 2012 I found no more of maritime books causing me the overwhelming desire to share, Like the few novels described in this section " Reading ”. Today this feeling comes back to me, in a completely different vein, on reading the excellent Special issue n° 48 of Voiles et Voiliers : " Understand and use electronic charting ”. Read more …

NV Chart extends coasts of France from SHOM

In a previous entry I presented the SHOM raster charts provided by many publishers on iPad. For several weeks the German nautical chart publisher NV Verlag offers two new areas ending coverage of the coasts of France Atlantic and English Channel. These charts are usable both with iNavX on iPad/iPhone, only with GPSNavX and MacENC on Mac. We can therefore, unlike Navionics, use the two available copies of each region on two different media (iPad , iPhone ou Mac).

Raster Charts… the comeback [Update]

[Update 26 August 2018]

I have been an ardent supporter of vector maps for several years.. Compact, of low numerical weight, easy to update, they are perfectly suited to use on our mobile devices.

According to the good old adage that only fools don't change their minds, Recent technical developments in hardware and software, added to maritime events that have occurred in recent years, have led me to reflect on the correctness of my opinion. Trained in the old school of safety in Glénans Sailing School, The only bias I must allow myself to express is that of the safety of human life at sea. This may sound a bit "old-fashioned" for some, but I assume. Hang, It's going to be a long time.

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.

Navionics Boating : Italian at the top of business [Update]

How make the new with the old ? Navionics knows it ! After publishing geographic areas including a navigation application, here is now an application, but without charting. Italian are too much !

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.

Charting compared, a mixed result

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.
