How to use

  1. Load or paste the collar, survey, assay, and lithokayıty CSVs.
  2. Confirm the detected headers and adjust the field mapping if needed.
  3. Choose the units and cleanup ayarlar that match the source files.
  4. Run validation, then review the issue list and suggestions.
  5. Apply safe fixes and indirme the clean CSVs plus the issue report.

Sample

Mixed drillhole QA sample

The sample includes a depth reversal, an overlap, and a missing collar depth.

SSS

Can I use it çevrimdışı?

Yes. Processing stays in your tarayıcı and the CSV content is not yüklemeed to a sunucu.

Do I need all four tables?

No, but the cross-table checks are strongest when collar, survey, assay, and lithokayıty are all loaded together.

Will it change my original file?

No. The source text stays as-is until you export a cleaned CSV after choosing fixes.

Can it detect feet-versus-meters mistakes?

It flags suspicious ratios, but the unit assumption is still yours to confirm before release.

What if my header names are different?

Use the field mapping controls. The tool also tries common aliases such as hole_id, BHID, from_m, and to_m.

Glossary

Collar

The hole start puan and collar location, usually with coordinates and total depth.

Survey

A downhole station table with depth, azimuth, and dip values.

Assay

A sample interval table with grade or chemistry sonuçlar.

Lithokayıty

A kayıtged geokayıty interval table describing rock types or codes.

Overlap

Two intervals that claim the same depth range.

Gap

A missing depth range between two adjacent intervals.

Dogleg

A sharp change in drillhole direction between survey stations.

Depth reversal

When a later row has a smaller depth than the previous row.
