Cosmological analyses require accurate measurements of object properties and a robust characterization of the image processing pipelines. We present a synthetic dataset of 5000 deg^2 of the DES footprint, that calibrates our galaxy measurements at the sub-percent level while accounting for all complexities in the image data/processing. We show how this approach enables the robustness of all science analyses derived from this data, and highlight how it can be leveraged for analyses of upcoming photometric surveys.
