Q1)

5. Given: the radius of the curve was 1000.00 ft, and A = 45 00'00', Drawing is not to scale. A total station instrument is setup at the PC, backsighting the PI, and 0 set. Determine the angle right (nearest second) and horizontal chord length (nearest 01 ft) to layout station 77+00.00. Assume 77+00.00 is on the curve. 20 pts PT PI POC 77+00.00 PC 70+00.00

Q 2 ) Exaplin why LiDAR has difficulty determining break lines when scanning the ground ??
