Changing the Resolution of Digital Surface Models

I’m having a bit of trouble with, what I assume is something fairly simple.

 

I’m attempting to produce Digital Surface Models (DSM) from lidar canopy data using the following methodology: http://www.youtube.com/watch?v=Ze4j5WV4ZZU

 

I have designed an algorithm to identify crown and sub-crown peaks within the DSM using DSM’s with different resolutions (i.e. Terrain models with courser resolution will only identify 1 crown for a given tree while those with finer resolutions may identify 3 or 4 smaller sub-crowns for the same tree).

 

I can’t seem to work out where in the methodology on the link I can modify resolution so as to generate finer and courser DSM’s.

 

Would someone be able to point me in the right direction?

 

Cheers

Matt
