2D Missing Line Routine
The 2D Missing Line Routine calculates distances and angles to describe the relationship between two points in
two-dimensional space (connecting vector). This routine is ideal for remote slope determinations and changes in
elevation from one location.
The simple routine prompts you to take two shots to targets: “Shot 1" and “Shot 2". The TruPulse L2 uses the results
to calculate values between the two points: slope distance, inclination, horizontal distance, and vertical distance
from Shot 1 to Shot 2.
• Slope Distance: Length of the missing line.
• Inclination between point #1 and point #2.
• Horizontal Distance: Horizontal component of the missing line.
• Vertical Distance: Change in elevation between point #1 and point #2.
NOTE See 2D Missing Line Routine Workflow on Page 19.
2D Missing Line Tips:
• Position yourself where shot 1 and 2 are made looking in the same direction with a clear line of site to both targets.
• The Vertical Distance Missing Line calculated value will always be accurate no matter which direction
shot 1 and 2 are taken.
• If Shot 1 is longer and higher than Shot 2, the VD value will be negative.
