Calculation method
Calculation method
Upward plane-normal [east,north,up]
Right-hand-rule dip azimuth=strike+90; normal=(sin dip sin dipaz,sin dip cos dipaz,cos dip).
Symbols and units
- a
- Strike azimuth, right-hand rule (degrees)
- b
- Dip below horizontal (degrees)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Strike, dip, convention. Returns Plane-normal vector. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Strike azimuth, right-hand rule (degrees): minimum 0, maximum 360. Dip below horizontal (degrees): minimum 0, maximum 90.
