Shom raster digital charts are in geotiff format, with a resolution of 300 dpi. They are the image of paper nautical charts and meet the obligations to carry nautical charts for pleasure craft less than 24 meters in length. For other categories of vessels they can only constitute an aid to navigation.

All nautical charts, paper or digital, are produced to order and benefit from the latest updates.

These charts are neither returned nor exchanged. Consequently, these orders are definitively concluded upon placing the order by the Customer in accordance with the terms specified in these General Terms and Conditions.
