Description
Zeeman Doppler imaging is the only observational method capable of providing
spatially resolved maps of stellar magnetic fields. This technique is routinely used
to reconstruct magnetic field topologies in different types of active stars. Recently
ZDI of cool stars was improved to include a more realistic treatment of the polarised
radiative transfer and a self-consistent modelling of the temperature and magnetic
structures. In some cases these methodological extensions led to a major revision of
ZDI maps. In this talk I will summarise basic principles of different versions of ZDI
and discuss key limitations and ambiguities of this technique.
