All surveying methods have different accuracy levels for determining the depths and positions.

Surveyors prefer the appropriate method for the survey. As a result of this, sometimes same survey

projects can be carried out with different accuracies. This confusion is removed by forming

surveying standards. In this way, consistency and uniformity could be provided. In this paper

different hydrographic survey standards are evaluated. In this frame, several hydrographic survey

standards belong to different organizations/offices (i.e. IHO S-44, USACE, LINZ, CHS, SMA and

NOAA) are investigated. Recent depth determination and positioning techniques with their

attainable accuracies are also introduced. These accuracies are compared to required ones described

in the standards. This study shows that today’s widely used depth determination and positioning

techniques can certainly meet the required accuracy levels.
