Quality control procedure for single beam hydrographic data, Version 1.

Abstract

An important driver for the Regional Coastal Monitoring Programmes is that all data collected and made freely available should be quality controlled in a thorough and consistent manner, to ensure that the data meets the specification, with the result that the data can be used subsequently with confidence for a wide variety of coastal engineering and management tasks. This document describes the stages used by the National Network of Regional Coastal Monitoring Programmes to quality control single beam hydrographic data. Quality control involves three types of checks: - the correct deliverables are provided; - the format and content of the deliverables are correct; - the quality of the survey data is met i.e. that it fulfils the requirements of the survey specification. The stages given herein are shown in a workflow which has been found by experience to be a practical and time-efficient route. Providing all the individual checks are carried out, they may be done in any order, using a suitable software programme, e.g. Hypack, ArcGIS.
