[OSRS-PROJ] projection software - swiss projection

[Nando Foppa]

Hello there,

I have an ER-Mapper file, which is a simple binary file (bil) and a
separate header file including all information about the file and the
projection (see below).
I would like to convert this file into the Swiss projection (Projection:
Oblique, Spheroid: Bessel).
As we work in an operational way, the reprojection should be made
without any human intervention and work automatically.
We work on a Linux environment and most programs are written in C or
IDL. We do not use an ER-Mapper software nor could we use ArcInfo
operationally.

I found several sources of public domain cartographic software that
perform projections but which software do you recommend?
Is PROJ.4 the best way?

Thank you a lot for your help and advice!!

Best regards,
Nando
