[GRASS-user] NED Shaded Relief, Grass 6.4

[Tripp Lowe]

Hello Folks,

I am trying to create a shaded relief map based on a 30-meter NED file using
r.shaded.relief.  The results are very 'blocky' (or stair-stepped).  Running
a 5-cell average neighborhood across the DEM did not help. Can somebody tell
me the correct procedures I should follow to create the relief map that is
smooth?

I've put a screenshot of my initial shaded relief map up here to show you
what I'm talking about...

Thank You Much.
