1. Project Setup
No project started.
2. CSV / Excel Import Wizard
Choose a module and select a CSV, XLSX or XLS file. The source file is read only; this prototype never edits it.
No file selected.
3. TideQC
Original observations remain separate from QC findings. No automatic correction is applied.
Import TideQC data first.

Use Zoom to enlarge a time window, then move along time to inspect it. Red points are preliminary flags only; no values are changed.
Suggested corrections — hydrographer review
Run preliminary checks to calculate review suggestions. Original imported readings are never changed.
