5: Survey Process and Terrain Models

Revised: 8-Dec-2022

Chapter 5 of the FLH OpenRoads Designer User Manual provides an overview of the survey processes used to create the Survey ORD File and Existing Terrain Model.  Manipulating the appearance of the Existing Ground Terrain Model is also discussed.

Additionally, this chapter provides workflow for acquiring LiDAR data and converting it into a Terrain Model.  The LiDAR Terrain Model can be used for initial design or merged with the Existing Ground Terrain Model to expand and/or fill in a gap.
