[Taxacom] Seeking Help with Co-ordinates

This projection system: Ocotepeque_1935_Costa_Rica_Lambert_Norte, looks 
suspiciously like what you've got.  The units are in meters.

The closest thing to a humanly understandable article about this 
projection system was found by Google at: 
http://www.asprs.org/a/resources/grids/04-2008-costarica.pdf

If it were me, I would let ArcGIS project those coordinates back into 
something usable like WGS 1984.  If you don't have ArcGIS or some such 
software, I did find a few articles that explained how to enter a 
transformation algorithm into your GPS, or (horrors!) make the 
calculations manually.

HTH,

Tom

The co-ordinates are L_N_184600_643400 and they can be found in a Specimen Data spreadsheet here ( http://www.inbio.ac.cr/papers/Elateriformes/Platycrepidius.html )
