Total Station Calculator

Compute horizontal/vertical distances and target elevation from total station measurements.

Slope Distance (ft)

Zenith Angle (degrees from vertical)

90 = horizontal, less than 90 = looking up, greater than 90 = looking down

Horizontal Angle / Azimuth (degrees)

Instrument Height (ft)

Prism Height (ft)

Station Northing

Station Easting

Station Elevation (ft)

Horizontal Distance

Vertical Distance

Target Elevation

Target Northing

Target Easting

Total Station Formulas

HD = SD * sin(ZA)

VD = SD * cos(ZA)

Target Elev = Station Elev + HI + VD - HT

dN = HD * cos(HA), dE = HD * sin(HA)
