  We derive a new discretisation method for first order PDEs of arbitrary
spatial dimension, which is based upon a meshfree spatial approximation. This
spatial approximation is similar to the SPH (smoothed particle hydrodynamics)
technique and is a typical kernel-based method. It differs, however,
significantly from the SPH method since it employs an Eulerian and not a
Lagrangian approach. We prove stability and convergence for the resulting
semi-discrete scheme under certain smoothness assumptions on the defining
function of the PDE. The approximation order depends on the underlying kernel
and the smoothness of the solution. Hence, we also review an easy way of
constructing smooth kernels yielding arbitrary convergence orders. Finally, we
give a numerical example by testing our method in the case of a one-dimensional
Burgers equation.
