Numerical values of single point soundings | This should be handled by an external database, similar to SRTM data for heights at land. | |
| I11 |      
|
Out of position soundings | This should be handled by an external database, similar to SRTM data for heights at land. | |
| I12 | 
|
Least depth in narrow channel | This should be handled by an external database, similar to SRTM data for heights at land. | |
| I13 | 
|
Non-bottom soundings | This is readings from echosounders where real seabed is deeper. Only way to survey the depth is by use of manual sounding. | |
| I14 |  
|
Unreliable soundings | Quality of seabed, sediments of water, or special conditions of currents and tides might give wrong readings, or the source are old or inaccurate. | |
