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.

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.
