946 rasterized charts based on vector chart material (ENC) provided by the AHS and displayed as raster tiles have been added in in the GeoGarage platform
including charts for Antarctica (x11), Papua New Guinea (PG x168), Solomon Islands (x43) and Tonga (x18)Acoording to our original commercial license with AHS, our derivated product based on geoTIFF material directly provided by AHS (so no their former Seafarer RNC raster navigational files available in HCRF - Hydrographic Chart Raster Format - also used at UKHO for ECDIS/ECS navigation with ARCS raster charts ) was explicitly not to be used for navigation so never available for W4D/SailGrib mobile apps. That was and remains currently the AHS policy as a result of the geoTIFF product specification - AHS doesn't not regard the production process as leading to a product that is suited to any purpose other than general desktop visualisation and GIS work -.
DISPLAYED CHARTS ARE NOT TO BE USED FOR NAVIGATION
