Raster charts coverage with map number for Australia
Right now, each nautical maps layer proposes a new feature to display the reference (number) for all the raster charts issued from each international Hydrographic Service.
To activate this feature, select the map layer and click on the 'coverage' button to see the different geographical areas.
This feature is available whatever you are logged in or not.
For 'private' layers depending on royalties to Hydrographic Services (UK & misc., Canada, Australia...), this allows the user to know exactly what he buys, subscribing to a 'Premium Charts' account.
