Inspect drillhole CSVs in the browser before they leave the workstation.
Load collar, survey, assay, and lithoskráy taflas together, yfirferð mismatches, and export clean CSVs without sending the data to a server.
The sample includes a depth reversal, an overlap, and a missing collar depth.

The sample includes a depth reversal, an overlap, and a missing collar depth.
Errors: 4 Warnings: 2 Fixable: 3 - DH-001 survey depth reversal at 45 m - DH-001 assay overlap at 18-20 m - DH-002 collar is missing total depth - DH-003 lithoskráy extends past collar depth
Yes. Processing stays in your browser and the CSV content is not uploaded to a server.
No, but the cross-tafla checks are strongest when collar, survey, assay, and lithoskráy are all loaded together.
No. The source text stays as-is until you export a cleaned CSV after choosing fixes.
It flags suspicious ratios, but the unit assumption is still yours to confirm before release.
Use the kortlagning sviða controls. The verkfæri also tries common aliases such as hole_id, BHID, from_m, and to_m.
The hole start point and collar location, usually with coordinates and total depth.
A downhole station tafla with depth, azimuth, and dip values.
A sample interval tafla with grade or chemistry niðurstaðas.
A skráged geoskráy interval tafla describing rock types or codes.
Two intervals that claim the same depth range.
A missing depth range between two adjacent intervals.
A sharp change in drillhole direction between survey stations.
When a later row has a smaller depth than the previous row.
