NHS Chart 77: Tjeldsundet - Harstad - Lavangen
This nautical chart is provided by the Norwegian Hydrographic Service (NHS). In 2011, The Norwegian Hydrographic Service (a division of Kartverket responsible for marine navigation in Norway) signed an agreement with OceanGrafix enabling authorization to print and distribute nautical charts for Norway. The 100+ charts—which comprise a majority of the charts produced by NHS—are updated regularly using the same technology OceanGrafix developed to print US charts on demand. Like NOAA charts, NHS charts are printed on demand and contain the latest chart information available at the time of printing.
