Data preparation for LiDAR

Inspection points

Inspection points with GPS coordination

Low quality and human error (ex. wrong pole ID)

Not every pole was inspected

Multiple inspection points for a pole

Recently inspected points is better but not always

Step 1. Multi inspection points

Re-build bay lines between poles

Look through the map at small scale (ex. 1:100,000)

Find zigzag lines and correct the position

Visual checking Point 1

Left over poles ( > 100 m or never inspected poles) are marked with special symbol if they are located at the end of line
