HI tomographic imaging of the Cosmic Dawn and Epoch of Reionization with
  SKA
  We provide an overview of 21cm tomography of the Cosmic Dawn and Epoch of
Reionization as possible with SKA-Low. We show why tomography is essential for
studying CD/EoR and present the scales which can be imaged at different
frequencies for the different phases of SKA- Low. Next we discuss the different
ways in which tomographic data can be analyzed. We end with an overview of
science questions which can only be answered by tomography, ranging from the
characterization of individual objects to understanding the global processes
shaping the Universe during the CD/EoR
