This tool displays a GB or Irish Grid Reference for a JPG file in Windows, if the photo has suitable GPS information. The Grid Reference is also copied to the clipboard, ready for pasting into a recording spreadsheet or website.
- Example GB grid reference:
NY 27332 33320, copied to the clipboard asNY2733233320. - Example Irish grid reference:
J 34386 74590, copied to the clipboard asJ3438674590. - Latitude, Longitude and other details such as tetrad are also listed.
The accuracy of the grid reference is primarily determined by the accuracy of the GPS reading in your phone or camera.
In many cases it may be best to express as a 6 figure grid reference eg NY273333 ie by removing the last two digits of each group.
- Once the tool is installed, right-click on a photo in Windows Explorer and select Grid Ref.
- If the Shift key is held down, then Eastings and Northings are found instead, eg
327332,533320 - If the Control key is held down, the location is shown in the default browser at streetmap.co.uk instead (only works in GB)
