[Taxacom] Fwd: Re: Seeking Help with Co-ordinates

[Daniel Janzen]

How to convert them?  Ask INBio for an output from ATTA in lat long 
decimal instead of the national mapping coordinates Lambert.  ATTA 
has Lat Long as well as Lambert.  You can ask the coordinator of 
INBio IT, Maria Auxiliadora Mora at mmora at inbio.ac.cr for such a list.
