What is Earthwork Volume Error in DEM Analysis about?

This document discusses a study that analyzes the relationship between errors in earthwork volume calculations using digital elevation models (DEMs) and terrain complexity for forest road construction projects. The study finds that volume errors from DEMs are correlated with terrain complexity, regardless of whether the volumes represent cuts, fills, or total earthwork. However, the correlation is weaker for cut volumes alone, possibly because slope angles are fixed at 90 degrees in the calculations. Unders
