Calculating Aspect from 10m and 30m DEM's, what is the best method?  How do they compare in results that are meaningful?  

Question asked by shawnar on Aug 8, 2018

Which is best to use for calculating Aspect of a point /transect line... a 10 m DEM or a 30 m DEM?  Would you use bilinear interpolation or or another type of method?  The transects range from 60-100 m long with multiple transects running perpendicular to the center transect; those transects range from 1 m out to approx. 40 m out from the center transect. (see attached)  Topography is a mountain cove.  Trying to determine the best method for calculating aspect values that are meaningful on the landscapes that we are dealing with.
