We present the first full six-dimensional panoramic portrait of theSagittarius stream, obtained by searching for wide stellar streams in the GaiaDR2 dataset with the STREAMFINDER algorithm. We use the kinematic behavior ofthe sample to devise a selection of Gaia RR Lyrae, providing excellent distancemeasurements along the stream. The proper motion data are complemented withradial velocities from public surveys. We find that the global morphologicaland kinematic properties of the Sagittarius stream are still reasonably wellreproduced by the simple Law & Majewski (2010) model (LM10), although the modeloverestimates the leading arm and trailing arm distances by up to $\sim 15$%.The sample newly reveals the leading arm of the Sagittarius stream as it passesinto very crowded regions of the Galactic disk towards the Galactic Anticenterdirection. Fortuitously, this part of the stream is almost exactly at thediametrically opposite location from the Galactic Center to the progenitor,which should allow an assessment of the influence of dynamical friction andself-gravity in a way that is nearly independent of the underlying Galacticpotential model.
