Plotroom
Read the waters your way
Use Day, Dusk, or Night chart palettes, choose the depth presentation, and reveal terrain or imagery ashore with Land only transparency.
Shared passage planning
See the plan the way the bridge will use it.
Plotroom keeps routes, chart context, review, and ECDIS handoff together—so the passage develops in one clear operational picture.
Accounts are reviewed before access is granted and assigned to the appropriate vessel and role.
One saved view carries the route, layers, camera, and chart presentation. Day and night chart palettes remain available independently.

A clearer planning picture
Chart, route, and operational context stay together.
Plotroom is organized around the decisions a navigator makes—not around separate files and disconnected displays.
Build a complete route
Edit waypoints, XTD, turn radii, speeds, stops, and fixed times on the chart or in the leg table. Plotroom fills the remaining schedule and flags conflicts.
Bring the useful layers aboard
Work with sea ice, planned survey areas, bathymetry, vessel positions, ship tracks, imported overlays, and external map services beside the route.
Examine the route before review
Use vessel safety settings to classify navigation regimes and check the route corridor against shallow water, land, and linked danger objects.
Keep decisions attached to the plan
Submit the route, comment against the relevant leg or waypoint, and carry the approved plan and its audit trail forward together.
Move cleanly to the bridge
Export the approved geometry and schedule for supported ECDIS systems, then verify the result on the vessel's certified equipment.
Keep fleet work organized
File routes, overlays, rasters, web layers, and tracks in personal, ship, and fleet libraries without making disconnected copies.
Return to the voyage record
Review approved passages by ship and date, export the bridge route again, and prepare a departure MOVREP from the recorded legs.
Layers with a purpose
Build the picture needed for this passage.
Routes, reference data, ship overlays, and vessel positions remain distinct and easy to control. A saved view recalls the exact working picture on another device or through a share link.
