Statistics and GIS assistance

An arrangement for help and advice with regard to and GIS is now in operation, principally for Master’s students.

How do you seek advice? 1. The users, i.e. students at INA, make direct contact with the person whom they think can help and arrange a time for consultation. Remember to be well prepared! 2. Doctoral students and postdocs register the time used in Agresso (if you have questions about this contact Gunnar Jensen).
