Abstract:

Digital terrain models (DTMs) are three-dimensional (3D) models of the ground surface showing natural features such as ridges and breaklines. This synthesis 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. Information for this study was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies. Six case examples provide additional information on DOTs’ experiences using DTMs during construction.
