How to use Grab a Grid Reference
To find a grid reference first select the desired scale boxes on the right. Drag the place marker on the map to the approximate location. Use the '+' button on the map to zoom in and then the 'Satellite' button for aerial image and adjust the place marker. The grid square of the selected resolution will be displayed on the map and the grid reference for that square will appear on the right-hand side.
Alternatively you can use the arrow buttons on the map or drag the map to the desired location and then hit the 'Get The Marker' button'.
To paste the grid reference into another document double-click to select, right-click and select 'Copy'.
To show the location for a known grid reference, type the reference into the box on the bottom right and press the 'Go To' button.
To share the resulting map with someone else, right-click on the 'Get a link to this location' link and select 'Copy link location'. This copies a URL link to this particular map into the clipboard which you can then paste into another document.
