A new layer in the GeoGarage platform : Argentina nautical charts based on rasterized ENC material from SHN

 Availability of a new dedicated layer for Argentina with SHN rasterized ENCs (full catalogue)
 
The layer also contains charts for Antarctica areas managed by SHN
so 6 ENC for : Coronation & Laurie Island, Esperanza, Primavera, Melchior, San Martin Bases & Deception Island
 
Until today, the GeoGarage platform used the raster paper chart material (RNC) provided by SHN to display nautical charts for the Argentina areas.

For internal management reasons specific to SHN (Serviceio de Hidrografia Naval) -the Argentina Hydrographic Office- has canceled the delivery of updated RNCs.
By the way, the availibility of RNCs was not completed (83 raster charts on a total of 144 paper maps).

The GeoGarage platform was already in the capacity to deliver a rasterized visualization of Electronic Navigation Chart (vector ENC) through their web services (WMTS) for their B2B customers involved in webmapping and other onshore GIS activities.

Today, the GeoGarage platform is now ready to propose the visualization of official ENC to their customers using mobile navigation apps (non SOLAS) so Weather 4D Routing and Navigation on iOS and SailGrib on Android.
 
In consequence, the GeoGarage platform no longer offers a subscription to Argentina Raster charts for Argentina on its e-commerce platform for mobile apps.
However, the Argentina RNC subscription will continue for their current mobile customers until its expiry date (visible on your W4D R&N/Sailgrib application) but will not be automatically renewed on this date.

The RNC plan is replaced by a new layer based on ENC type maps edited by the Servicio de Hidrografia Naval (SHN), and rasterized for W4D/Sailgrib : Argentina (derived from SHN ENC)
The price of the annual subscription is now 38.99 EUR.
 
So Weather4D R&N and Sailgrib users (with last updated versions) can right now display the whole catalogue of NLHO ENC (107 ENC at this time), with a half-yearly updating process : see GeoGarage news

Today, in this first version, the vector ENC are displayed using a graphical rendering similar to the one used in official ECDIS (s-52 IHO specifications) : they are not to be used for shipping navigation (IMO SOLAS), but only for recreative use, not as a primary tool for navigation.
Effectively, in contrast to the use in ECDIS, there is no possibility -today with the W4D/SailGrib current version- to ask for text info and details regarding any navigational objects (beacon, buoy, marks...).
