Plotroom is a web application for building, checking, and approving vessel voyage routes over live nautical charts — then exporting them to the formats your bridge and planning systems already use.
New accounts are reviewed and approved by an administrator, who assigns your role and vessel.
From a blank chart to an approved plan ready for the bridge.
Plan over NOAA ENC charts with selectable basemaps, adjustable chart transparency, and depth shading.
Build and edit routes on the map and in a leg table — waypoints, turn radii, speeds, and cross-track distance.
Mix fixed speeds, fixed ETAs, and stops; the solver fills the rest and flags anything infeasible.
A draft-driven safety contour, four-shade depth display, and automatic navigational-regime classification.
Submit a route for review; the Commanding Officer approves or returns it, with per-leg comments and an audit trail.
Import survey areas and user charts, or draw your own objects, and link them to the routes they affect.
Round-trip routes as RTZ, plus GPX and vendor ECDIS dialects; overlays as shapefile and GeoPackage.
See fleet positions from public AIS feeds and review recorded track history alongside your plans.
Generate a printable passage plan — overview, full leg table, and an approval block — as HTML or PDF.
The same tools throughout — plan, check, and hand off.
A simple review flow keeps everyone working from the approved version.
Create a route on the chart or import an existing RTZ/GPX, then edit and solve its schedule.
Run the route check and set the safety contour and regimes before it goes for review.
Submit for review; the CO approves or returns it with comments — everyone sees the current status.
Export the approved plan to your ECDIS/planning-station format and the printed passage-plan sheet.
Mariners juggle several route formats and programs. Plotroom imports and exports the common ones so a plan moves cleanly between planning stations, ECDIS units, and GIS.
Build routes on live charts, solve the schedule, and prepare the passage-plan package.
Draft and submit routes, add comments, and work from the current approved version.
Review, comment, and approve — with a clear audit trail of who changed what and when.
