OSI Map Viewer

[fitzet]

Not a technical problem, as such, but this is probably the appropriate section to post.

I'm planning two mountain/big hill trips before the end of October and have being using the OSI (Ordnance Survey Ireland) Map Viewer to get a better idea of the routes to take. Each of these involves a cache or two (natch ).

It's years since I did any sort of map work and I may have to do some revision but ..

Is there a way to convert the OSI X/Y references to GPS data, e.g. N 53 NN.NNN W 06 NN.NNN ? I assume that the OSI map data is local to Ireland so if there were a method for converting one to the other, it would have been developed locally.

For example, could I take the GPS co-ordinates off a cache listing and convert them to an 'OSI' equivalent ?

Thanks

PS I know I could probably achieve the same outcome by RTFMing my GPSr manual

If you save a waypoint in your GPS in the format N 53 NN.NNN W 06 NN.NNN

Then go to your GPS settings, and change the positional format to either Irish Grid (IG) or Irish Transverse Mercator (ITM)

If you then go back to your map, or bring up the information on the waypoint you created it will now magically show in IG/ITM

Thanks
And would it work in reverse, i.e. store in ITM and let the GPSr display as N 53 NN.NNN W 06 NN.NNN ?

And, since posting, I came across this.
