Geospatial Positioning Accuracy Standards, Part 5: Standards for Nautical Charting Hydrographic Surveys

Document number

FGDC-STD-007.5-2005

Maintenance authority

Office of Coast Survey, National Ocean Service, National Oceanic and Atmospheric Administration

Objectives

This standard provides minimum standards for the horizontal and vertical accuracy of features associated with hydrographic surveys that support nautical charting.  Such features include, but are not limited to, water depths, objects on the seafloor, navigational aids, and shoreline. 

Scope

For the purposes of this Standard, hydrographic surveys are defined as those surveys conducted to determine the configuration of the bottom of water bodies and to identify and locate all features, natural and man-made, that may affect navigation.  Nautical charts are compilations of data from numerous sources, principally hydrographic surveys, designed specifically to meet the requirements of marine navigation.  The scope of these standards includes the coastal waters of the U.S. and its territories.
