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 BAG 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).
• Evaluate chart-scale soundings and features versus survey-scale soundings via “triangle rule” (see Triangle rule).
• Scan HCell features to ensure proper attribution (see Scan features).
