The network or collaboration map is based upon the institutional affiliations of your co-authors from your publications in the research portal. Please note that unless at least a country has been specified (and ideally a state and city) for the institute, it will not show up on the network map.
(De)activate the network map
By default, the network map is shown for every faculty, department, section and researcher. You can (de)activate the 'collaboration map' on your profile page. You will find this setting under the 'Portal profile' tab on the 'Edit profile overview'. You can change this setting at any time.
