Search and Locate
Grid References
Use the grid-reference tool when you already know an Ordnance Survey location and want OMN4 to go straight there or create a waypoint.
Open The Tool
Open the grid-reference or direct-location tool from the main map, then choose British National Grid.
Enter A Grid Reference
You can work in two ways:
- enter a full grid reference with the two-letter square, such as
ST 123 456 - turn off Use prefix letters and enter easting and northing separately
If you use numeric eastings and northings, choose the precision that matches the numbers you are entering.
Go Or Save
After OMN4 accepts the entry:
- tap Go to move the map there
- tap Add Waypoint to save the location as a waypoint as well
Tips
- Enter an even number of grid-reference digits so OMN4 can split easting and northing correctly.
- If the result looks wrong, check the grid square letters first.
