The UMARK website - About the author

Dear Visitor,

my name is Udo Mark, I am 68 years old, and I am living in Oberpframmern, a small community in the lovely country southeast of Munich, Bavaria.

I am holding a degree in electrical engineering & cybernetics from Munich Technical University and have been affiliated with a major technology and consulting company near Munich,
working in the field of remote sensing, aerial imagery, optoelectronics and infrared physics.

I am married, have a 35-year-old daughter and three grandchildren and have been widely enjoying skiing and climbing in the nearby mountains of the Bavarian Alps.
As another facet of my private life I have been busy with mathematics, astronomical timekeeping and calendar regulations for a number of years now.
An outcome of this activity are the software packages on this website - they are genuine no-frills, no-gimmicks Fortran console applications, and I hope they will well serve an interested community.

For the exchange of ideas regarding the issues addressed in these software packages, please feel free to contact me:

Udo Mark
