This document describes HydrOffice QC Tools 4.9.9.

2.3.8.1. How To Use?

Ensure the least depth of features match the gridded bathymetry.

In order to access this tool, load a grid and an S-57 file into the Data Inputs tab.

  • Select the VALSOU Checks tab (Fig. 2.48) on the bottom of the QC Tools interface.

  • In Parameters:

    • The Include TECSOU=laser checkbox may be enabled (in the event of lidar bathymetry wherein we’d expect features to be represented in the grid), or disabled (as in the case of shoreline investigations where the VALSOUs are not derived from the surface).

  • In Execution, click VALSOU Checks

  • After computing, the output window opens automatically, and the results are shown (Fig. 2.49). Note, the check considers all combination of grids and features files loaded. If there is no overlap found between a grid and feature file, no output is generated, and the summary will report “no overlap”.

  • From the output window, drag-and-drop the output into the processing software to guide the review.

Note

VR CSAR: this tool may provide false positives due to current limitations in accessing designated soundings through the CARIS SDK.

Note

VR BAG: this tool may provide false positives because grids created with CARIS apps do not currently contain the location of designated soundings.
