CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated survey horizontal distance projection: solve measured slope distance relation over the valid real-number domain stated below. The implemented relation is a=c/cos(b), evaluated from horizontal distance projection, vertical angle magnitude in degrees to produce measured slope distance. Horizontal survey distance is the slope distance multiplied by the cosine of the vertical angle magnitude. This page isolates measured slope distance and verifies it in the original relationship. Confirm whether the instrument reports angle from horizontal or zenith, apply curvature and refraction when material, and reduce instrument and target offsets consistently.
Inputs and valid domain
- horizontal distance projection must be a finite real number.
- vertical angle magnitude in degrees must be a finite real number.
Important boundary: Confirm whether the instrument reports angle from horizontal or zenith, apply curvature and refraction when material, and reduce instrument and target offsets consistently.
The formula
a=c/cos(b)
How the calculator works through it
It substitutes horizontal distance projection, vertical angle magnitude in degrees into the formula and exposes every numerical step above. The main output is measured slope distance, accompanied by Reconstructed horizontal distance projection.
Read the result correctly
The measured slope distance is the direct answer to “rearrange the survey horizontal distance projection relationship and solve for measured slope distance.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
measured slope distance=120 and vertical angle magnitude in degrees=12 produce horizontal distance projection=117.37771208805668.
Where this model stops being reliable
Confirm whether the instrument reports angle from horizontal or zenith, apply curvature and refraction when material, and reduce instrument and target offsets consistently.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
