Latitude/Longitude -> Irish Grid class/DLL

[almurph]

Folks,


I'm looking for a VB.NET class or DLL that will convert latitude/
longitude to Irish Grid or IMT (Irish Traverse Mercator) co-ordiates.
Anyone with any suggestions? Any comments/ideas/leads much
appreciated.

Cheers,
Al.

How would you do it manually? Is there a conversion formula that you
know of?

Thanks,

I don't know of a vb package. You should look into GeoTrans at
http://earth-info.nga.mil/GandG/geotrans/. You will probably need to roll
your own definition for the output since the two you mentioned are just
offsets from standard projections. Java and C++ code is included.
