2.3.6. Scan features

2.3.6.1. How To Use?

Scan features to ensure proper attribution and cartographic disposition.

• Select the Scan Features tab on the bottom of the QC Tools interface.
• In Parameters (Fig. 2.40, left side), turn the knob to select the required year of HCell Specification. Currently, the ‘2018 test’ is duplicative to 2016.
• In Execution (Fig. 2.40, right side), click Feature scan v2.

Fig. 2.40 Feature scan’s interface.

• After computing, the output window opens automatically, and the results are shown (Fig. 2.41).

• From the output window, drag-and-drop the output into the processing software to guide the review.
• In addition, the results are printed to PDF for a documented summary.

2.3.6.2. How Does It Work?

The S-57 features are scanned to ensure proper attribution and chart disposition per the required year of HCell Specification. Listed within the specification are mandatory requirements and S-57 attribution.

The QC Tools Chart feature scan will ensure the following:

• No redundant features.
• CS Soundings have an accompanying SS Sounding.
• All feature VALSOU have an accompanying SS Sounding.
• No feature VALSOU coincide with a CS Sounding.
• No objects have prohibited attribute SCAMIN.
• No objects have prohibited attribute RECDAT.
• No objects have prohibited attribute VERDAT.
• All objects have mandatory attribute NINFOM. [1] [2014]
• All objects have SORIND. [2]
• All objects have SORDAT. [2]
• No SOUNDG have prohibited attribute STATUS.
• All Wrecks must have mandatory attributes CATWRK, WATLEV, VALSOU, and QUASOU.
• All Wrecks with WATLEV = 5 (awash) must have mandatory attribute EXPSOU. [2016]
• All UWTROC must have mandatory attributes VALSOU, WATLEV, and QUASOU.
• All OBSTRN must have mandatory attributes VALSOU, WATLEV, and QUASOU.
• No OBSTRN with CATOBS =6 (foul area). [2014]
• All MORFAC must have mandatory attribute CATMOR.
• No MORFAC have prohibited attributes BOYSHP, COLOUR, or COLPAT. [2016]
• All SBDARE points must have mandatory attribute NATSUR.
• No SBDARE points have prohibited attributes COLOUR or WATLEV.
• All SBDARE points have an allowable combination of NATSUR and NATQUA noted by ‘x’ in the table below.

NATQUA: fine (1), medium (2), coarse(3), broken (4), sticky (5) soft (6), stiff (7), volcanic (8), calcareous (9), hard (10)

NATSUR: mud (1), clay (2), silt (3), sand (4), stone (5), gravel (6), pebbles (7), cobbles (8), rock (9), lava (11), coral (14), shells (17), boulder (18)

• All SBDARE lines and areas must have mandatory attribute NATSUR and WATLEV.
• All COALNE must have mandatory attribute CATCOA.
• No COALNE have prohibited attribute ELEVAT.
• All CTNARE must have mandatory attribute INFORM. [2016]
• All SLCONS must have mandatory attribute CATSLC.
• All M_QUAL must have mandatory attributes CATZOC, TECSOU, SURSTA, and SUREND.
• All M_CSCL must have mandatory attribute CSCALE.
• All M_COVR must have mandatory attribute CATCOV.
• All cartographic objects must have mandatory attributes NINFOM and NTXTDS. [3] [2014]
• All cartographic objects must have mandatory attribute INFORM. [3] [2016]
• All objects with NOAA extended attributes still populated are tallied and presented (display only) as a reminder to clear before final submission.
