Convert a total station slope distance to horizontal distance and elevation difference using the vertical angle.
斜距 S 与竖直角 α 换算为平距与高差,用于高程传递
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Horizontal distance | S = D · cos(alpha), where D is the slope distance and alpha the vertical angle | GB 50026-2020, Code for engineering surveying |
| Height difference | h = D · sin(alpha) + instrument height - target height | GB 50026-2020, Code for engineering surveying |
| Zenith-distance form | S = D · sin Z; h = D · cos Z, where Z is the zenith distance | GB 50026-2020, Code for engineering surveying |
| Instrument corrections | Apply additive, scale and meteorological corrections to the results | GB 50026-2020, Code for engineering surveying |
