2.2.5. Grid QA — HydrOffice QC Tools 2.7.0 documentation
The Depth, Uncertainty, Density (if available), and a computed Total Vertical Uncertainty (TVU) QC layer (optional) are used to compute particular statistics shown as a series of plots. The TVU QC is either given to the program in the grid input, or calculated on-the-fly.
2.2.5.2. How Does It Work? — QC Tools 4.4.5 documentation
The Depth, Uncertainty, Density (if available), and a computed Total Vertical Uncertainty (TVU) QC layer are used to compute particular statistics shown as a series of plots. The following plots are the output of Grid QA:
Oct 24, 2014 · Specifically, this tool may be used to confirm that (i) at least 95% of the nodes in a finalized surface have a Total Vertical Uncertainty (TVU) within the maximum allowable error given by the appropriate IHO order as a function of depth (i.e., TVU QC = node uncertainty / node maximum allowable uncertainty <= 1.0) and (ii) at least 95% of the no...
