2025.40.1 Chart update

Improved visuals and expanded coverage

Visuals

• Navigation critical Restriction Zones are now visualized with distinct symbols

• Improved label presence and reduced label overlap for bridges, marks, and buoys

Coverage and data

• Expanded chart coverage in inland Netherlands with high-resolution bathymetry. Key expansion covers Fluessen, Heegermeer, Slotermeer, Sneekermeer, Tjeukemeer, and other lakes and connected canals in Friesland and Groningen. Southwards, the Veluwemeeer, Eemeer, and Gooimeer have also received high-resolution bathymetry updates.

Note: UKHO has stopped supplying GB5DNABJ – Thames Estuary & River Roach chart data due to sub-licensing restrictions. Chart data removal like this happens from time to time. Usually, in cases like these, the Hydrographic Office supplies replacement data. GB5DNABJ has not yet received a replacement, which means for the current chart release, there will be no coverage in the area. We are working with UKHO to find alternative data for Thames Estuary & River Roach coverage.
