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 TruPoint uses the
results to calculate four variables between the two points: slope distance, inclination, horizontal
distance, and vertical distance as shown in Figure 25.
If you were to actually stand at the location of Shot 1 and take a measurement to Shot 2, the calculated
values would be from Shot 1 to Shot 2. If the first shot is father away and higher than the second shot,
the measurement values: HD, SD will be positive values and INC, VD will be negative values. If the
first shot is closer than second shot, the measurement values: HD, SD, INC, VD will be positive
values.
