Create Waypoint Data
To create a GPX Waypoint file, type or paste in a series of ID and OSGB values, e.g.:-
0901,SK 16391 50428
0902,SK 14756 53745
Alternatively just enter one grid reference per line and the ID will
be automatically created, in the range 0000 to 9999.
To add a prefix to this number simply do a global edit, on the gpx data, using a text editor.
e.g. change <name> to <name>prefix
Note.
All spaces, in the grid reference, are removed before processing.
