Spectra Precision Survey Pro v5.0 - Manual (Page 189)

[Azimuth] / [Bearing]: defines the direction of the boundary sides with lengths that are not yet known.
Results
Point 1 / 2: Displays the coordinate of the end points of the computed boundary line.
Total Area: is the total area of the boundary.
Plot Area: is the area enclosed by the pre-defined fixed boundary lines.
Difference: is the difference between the Total Area and the Plot Area.
HD/VD to SD/ZA
[Cogo] [HD/VD to SD/ZA]
The HD/VD to SD/ZA screen will convert a vertical and horizontal distance to an equivalent slope distance and zenith
angle.
Horz Dist: is the horizontal distance from the occupy point to the foresight point.
Vert Dist: is the vertical distance from the occupy point to the foresight point.
HI: is the distance that the total station is above the ground.
HR: is the length of the rod.
[Earth Curvature and Refraction]: Set the earth curvature and refraction correction coefficient. Select [None] to turn
earth curvature and refraction correction off for all observations from this station setup.
[Solve]: computes the equivalent slope distance and zenith angle from the data entered.
Results
Zenith: is the computed zenith angle from the occupy point to the foresight point.
Slope Dist: is the computed slope distance from the occupy point to the foresight point.
SD/ZA to HD/VD
[Cogo] [SD/ZA to HD/VD]
The SD/ZA to HD/VD screen will convert a slope distance and zenith angle to an equivalent horizontal distance and
vertical distance.
Slope Dist: is the slope distance to be converted.
Zenith: is the zenith angle to be converted.
HI: is the distance that the total station is above the ground.
HR: is the length of the rod.
