Bug within Garmin BlueChart maps

[pegase35]

Hi all,
In first, excuse my bad english (I am french ).
For many years I have used the Garmin bluechart for my navigation.
Today, I have found a very big bug on all the maps created from the SHOM maps (for the other countries, I don't know). In France, the maps used to create the electronic sea maps comes from the SHOM.
On a SHOM map, you have a letter to define the sea floor (M for Mund, S for Sand, R for Rock ...).
When the BlueChart maps are created from the SHOM maps, all the signs "R" to define a see floor of Rocks becomes a shallow. It's completly different
If you want an example:




This problem is present on BlueChart 9.5 and also on G2 and G2 Vision.
Have you already seen this problem???

Best regards.

Have you contacted Garmin about the problem

[pegase35]

Yes, I send a mail to Garmin France yesterday and I wait their response.
In the same way, I have also find an issue in Navionics maps (in France, there is a new island in Britanny ) but I don't a user of Navionics maps so I don't contact the company. For the Garmin problem, I am very disapointed .
Have a nice day.

Pegase,
Where did you find a new island on a Navionics chart in Brittany? This is where I usually sail!

Looks at the end of this web page: Logiciel NavPlanner pour cartographie Navionics
You will see a little island in front of Dinard in the North of Britanny. In fact on the SHOM map, it's only few rocks in the foreshore.
It's a document of my website (only written in French but for you Alain, I think it doesn't a problem ).
Best regards.
