High qaulity Terrian DEM

[TheConductor]

I have noticed lately that the dem files i have are very blocky and not as good as the terrain used on other routes. So to test this i opened a route that was built in an area that only had 1/3 arc second on the usgs map and then it re generated that 1x1 chunk useing my DEM data from the usgs site that was 1/3 arc second but the terrain i generated was very blocky. Is there a step im missing or something because my 1/3 arc second looks nothing like what many riute builders are useing.
