Canada CHS update in the Marine GeoGarage

As our public viewer is not yet available
(currently under construction, upgrading to a new viewer
as Google Maps API v2 is officially no more supported),
this info is primarily intended to our universal mobile application users
(Weather 4D Android -App-in- on the PlayStore)
and also to our B2B customers which use our nautical charts layers
in their own webmapping applications through our GeoGarage API.

So 793 charts (1680 including sub-charts) are available in the Canada CHS layer. (see coverage)
note : in the previous updates, the letters in the chart number (xxxxA/xxxxB) were not taken into account : so 696 BSB charts were in fact 793 (taken into account all the chart numbers)

Note : don't forget to visit 'Notices to Mariners' published monthly and available from the Canadian Coast Guard both online or through a free hardcopy subscription service.
This essential publication provides the latest information on changes to the aids to navigation system, as well as updates from CHS regarding CHS charts and publications.
