2.3.1. Overview

The Chart Review tab will:

• Ingest a bathymetric grid, sounding selections, and feature files (see Data inputs).

• Truncate grid elevation to decimetric precision (see Grid truncate).

• Export grid elevation as ASCII XYZ file (see Grid xyz).

• Truncate all “z” values in an S57 file to decimetric precision (see S57 truncate).

• Scan HCell features to ensure proper attribution (see Scan features).

• Evaluate chart-scale soundings and features versus survey-scale soundings via “triangle rule” (see Triangle rule).
