Map sources
Maps
OMN4 brings map sources into one desktop and mobile workflow. Ordnance Survey is the Great Britain launch strength, with worldwide map context available for broader planning and review.
Great Britain launch source
Ordnance Survey
Licensed Great Britain mapping for route planning, offline use, and desktop printing, subject to subscription.
- 1:25,000 Explorer mapping for detailed walking and outdoor route work.
- 1:50,000 Landranger mapping for broader cycling, touring, and longer routes.
- 1:10,000 OS VectorMap Local detail in the Pro GB plan.
Worldwide context
OpenStreetMap and worldwide coverage
Low-detail worldwide coverage for wider map context while OMN4 grows beyond the Great Britain launch.
- Useful as broad worldwide context, not the main launch map sell.
- Works alongside OMN4 routes, tracks, waypoints, and GPX.
- More detailed worldwide mapping can be added when it is ready.
Plan and download deliberately
Use the map source that fits the trip, then download the areas you need on the device that will use them.
Use maps with routes and GPX
Map sources sit inside the same OMN4 route, track, waypoint, and GPX workflow.
Print and review with confidence
Use detailed maps with route work, GPX, and desktop printing when a paper backup helps.
