Assessment of IHO Compliance and Quality Control Report
Crosslines totaling approximately 5% of mainscheme were surveyed for Registry
# H12005. Only one cross line was completed for Registry #H12006 due to time
restraints. CARIS generated Quality Control Reports were compiled for each survey area.
This routine compares the crosslines for each project against the 2m depth BASE surface.
The graphs in Appendix K are a cumulative representation of the IHO compliance of
each region against the BASE depth surface. The results of the QC report are based on
individual HDCS soundings from the crosslines, to a BASE surface created from the
mainscheme data. Comparing HDCS crossline data to a mainscheme BASE surface may
introduce, or reduce, errors, depending on results of comparisons between surfaces and
individual soundings. In addition to comparing the crosslines to mainscheme data, the
CARIS BASE surface QC report was also performed. This utility compares uncertainty
values contained in the surface to IHO standards and created a compliance report that is
included in Appendix K. Registry Number H12005 met and exceeded IHO compliance
for IHO order 1 for depths shoaler than 100m, and IHO order 2 for depths deeper than
100m. Registry Number H12006 partially met and exceeded IHO compliance for IHO
order 1 for depths shoaler than 100m, and IHO order 2 for depths deeper than 100m. It is
a high probability that this is a result of only one cross line of data was available for
comparisons.
