Pixels to physics: the promise and challenges of survey cosmology

We are entering a transformative period in observational cosmology.  Large cosmological surveys starting in 2019 promise to solve key problems in cosmology - but only if we develop new approaches for handling the volume and complexity of the data.  Extracting robust cosmological information from these surveys is a major challenge that will require development and validation of analysis methods at each step of the chain from raw pixels to cosmology.  I will comment on some of the experimental and methodological innovations that are needed to realise the promise of upcoming surveys.
