I have a younger colleague who is considering a GIS masters degree and she has asked my advice. She is already a proficient GIS user but not qualified in the field. I want to give her the best advice I can, so I'm trying to make sure she considers complementary skills that could enhance her GIS, in addition to simply becoming a more qualified practitioner.
I have thought of graphic design as being one element that a lot of GIS practitioners might be lacking in, but I'm not sure. I'm sure many of you will have better answers than I, so I'd appreciate knowing what skills you think would improve you as a GIS user or practitioner.
