Digital terrain models (DTMs) are 3D models of the ground surface showing natural features such as ridges and breaklines. TRB will host a webinar on Monday, November 15, 2021 from 1:00-2:30 PM Eastern that will discuss current strategies state departments of transportation (DOTs) use to employ DTMs in constructing highway projects. Presenters will identify how to use DTMs and portray benefits and challenges. They will also discuss lessons DOTs learned from using DTMs.

This webinar features research from NCHRP Synthesis Report 560: Practices for Construction-Ready Digital Terrain Models.

Some registrants will need to pay $95 to attend this webinar. Sign into to view registration information.
