Two formats of nautical charts are available:
Mapmedia nautical charts: This format of nautical charts is developed by the computer company&mer and only works with maxsea. The coverage is global and the proposed nautical charts are from official hydrographic services, which facilitates the transition from paper nautical charts to digital mapping. These charts are available at a competitive price in different zone formats (standard zone, wide zone and mega wide zone). Note that tidal current maps are also available.
Maptech nautical charts: Maptech distributes nautical charts in bsb format (this is the official format of the NOAA (National Ocean & Athmospheric Administration)). This format of nautical charts promoted by the Americans and distributed by Maptech is a proprietary format that has one of the best covers in the world. The nautical charts available for France are those of the Shom. Note that mapmedia charts are distributed with the offshore navigator lite software
