Abstract

We present the February 2019 12th Square Kilometre Array (SKA) Pathfinder HI Survey Coordination Committee (PHISCC) workshop to be hosted in Perth, Australia. The PHISCC organises regular biannual (or annual) international meetings to coordinate scientific, observational and processing topics with regards to the HI surveys associated with the commissioning and the recently-commissioned SKA pathfinder facilities. This includes the development of scientific ideas and priorities, as well as technical tools to tackle common challenges such as RFI mitigation, visualization, source finding, data analysis, archive management and the acquisition of ancillary data.
