Practices for Construction-Ready Digital Terrain Models
Digital terrain models (DTMs) are three-dimensional (3D) models of the ground surface showing
natural features such as ridges and breaklines.
The TRB National Cooperative Highway Research Program's
NCHRP Synthesis 560: Practices for Construction-Ready Digital Terrain Models
documents processes and
strategies used by state departments of transportation (DOTs) for the use and transfer of DTMs
from design into the construction phase of highway projects.
