Hello,

I'm new to proj and I need to convert some coordinates from wsg84 to tmerc.

The source coordinates comes from a gps device which uses wsg84 and I
would like to convert them to:

PROJCS["Datum_73_Hayford_Gauss_IPCC",
    GEOGCS["GCS_Datum_73",
        DATUM["D_Datum_73",
            SPHEROID["International_1924",6378388.0,297.0]],
        PRIMEM["Greenwich",0.0],
        UNIT["Degree",0.0174532925199433]],
    PROJECTION["Transverse_Mercator"],
    PARAMETER["False_Easting",180.598],
    PARAMETER["False_Northing",-86.99],
    PARAMETER["Central_Meridian",-8.131906111111112],
    PARAMETER["Scale_Factor",1.0],
    PARAMETER["Latitude_Of_Origin",39.66666666666666],
    UNIT["Meter",1.0]]

This info was taken from a ESRI *.proj file and I believe that it
contains all the information needed, but I haven't found the right way
to use it.

Can anyone help?

Thanks

David Vaz
