When Accuracy Matters:
We just completed another successful sub 2cm design survey on a 6 mile section of 6 lane divided freeway including 3 interchanges. Crews placed 415 control targets that were precisely digital leveled. 125 of those targets were used for trajectory control and the remaining 290 were independent validation targets. All 415 targets were within the DOT standard of 2cm (0.06') maximum deviation in X,Y and Z.
Below are some screen shots of the final RGB point cloud that will be used to produce full 3D planimetric mapping deliverables to DOT specifications, including detailed DTM surface modeling.
