  A new Gas Puff Imaging (GPI) diagnostic has been installed on the TCV
tokamak, providing two-dimensional insights into Scrape-Off-Layer (SOL)
turbulence dynamics above, at and below the magnetic X-point. A detailed study
in L-mode, attached, lower single-null discharges shows that statistical
properties have little poloidal variations, while vast differences are present
in the 2D behaviour of intermittent filaments. Strongly elongated filaments,
just above the X-point and in the divertor far-SOL, show a good consistency in
shape and dynamics with field-line tracing from filaments at the outboard
midplane, highlighting their connection. In the near-SOL of the outer divertor
leg, shortlived, high frequency and more circular (diameter $\sim$15 sound
Larmour radii) filaments are observed. These divertor-localised filaments
appear born radially at the position of maximum density and display a radially
outward motion with velocity $\approx$400\,m/s that is comparable to radial
velocities of upstream-connected filaments. Conversely, in these discharges
($B\times\nabla B$ pointing away from the divertor), these divertor filaments'
poloidal velocities differ strongly from those of upstream-connected filaments.
The importance of divertor-localised filaments upon radial transport and
profile broadening is explored using filament statistics and in-situ kinetic
profile measurements along the divertor leg. This provides evidence that these
filaments contribute significantly to electron density profile broadening in
the divertor.
