Forward
Use start point, azimuth, dip, and length to calculate the end point and deltas.
Penukar XYZ dan Azimut/Ceran
Convert azimuth, dip, and length to XYZ, or reverse XYZ back to azimuth and dip.
Keep true / grid / magnetic north notes alongside mining, borehole, and underground survey records.

Apa yang anda boleh lakukan
Forward
Compute XYZ from azimuth, dip, and length
Add the direction vector to the start point to calculate the end point and deltas.
Inverse
Reverse XYZ back to azimuth, dip, and length
Use two points, or the differences between them, to recover the line orientation.
North reference
Keep true / grid / magnetic north notes visible
Store a correction angle and a reference note so the survey assumption stays in view.
CSV
Convert CSV in bulk
Auto-detect headers and delimiters, then process mixed Forward / Inverse rows together.
Sharing
Copy rows, JSON, CSV, and share links
Move a single result or the whole session to another device without server upload.
Cara guna
- Choose Forward, Inverse, or Batch CSV as the entry mode.
- Set the coordinate display and north reference, then add a correction angle and reference memo if needed.
- In Forward mode, enter the start point, azimuth, dip, and length to get the end point. In Inverse mode, enter the start and end points to get the direction.
- For CSV, paste the rows or load a file, review the converted table, and export it when it looks right.

Glosari
Azimut
A horizontal angle measured clockwise from north.
Dip
The angle from the horizontal plane, with downward positive in this tool.
ENU
East / North / Up. This is the internal calculation basis.
NED
North / East / Down. Often used in mining and aviation contexts.
Utara sebenar
North that points toward the geographic pole.
Grid north
North aligned with a map or projected grid.
Magnetic north
North indicated by a compass. It changes by place and time.
DMS
Degree / Minute / Second angle notation.
Formula
H = L × cos(dip)ΔE = H × sin(azimuth)ΔN = H × cos(azimuth)ΔU = -L × sin(dip)L = sqrt(ΔE² + ΔN² + ΔU²)azimuth = atan2(ΔE, ΔN)dip = atan2(-ΔU, sqrt(ΔE² + ΔN²))azimuth_true = normalize360(azimuth_input + offset_to_true)
Soalan Lazim (FAQ)
Adakah cerun di sini cerun geologi atau cerun garisan?
Ia dianggap sebagai cerun garisan. Alat ini tidak menyelesaikan strike / cerun untuk satah.
Are true north and grid north calculated automatically?
You can show a conversion if you enter a correction angle, but the tool does not calculate it from map or magnetic models.
Can I paste azimuth values in DMS format?
Yes. Formats such as 123°27'24", 123 27 24, and 123:27:24 are accepted.
What happens for a vertical segment?
Length still calculates, but the azimuth becomes undefined in the inverse direction.
What CSV formats are supported?
Both headered and headerless input are supported, and comma / semicolon / tab delimiters are auto-detected.
Di mana data disimpan?
By default it stays in the browser. CSV bodies are not put into the URL, so share them as files when needed.
Catatan
- Alat ini ialah bantuan penukaran. Ia tidak menggantikan hasil ukur atau piawaian tapak.
- Azimuth is measured clockwise from north, not like a standard mathematical angle.
- Cerun dianggap sebagai cerun garisan, bukan pasangan strike / cerun bagi satah.
- True / grid / magnetic north corrections are supplemental notes based on the values you enter.
- CSV headers are auto-mapped, but checking the template on the first run is still recommended.
