Hydrographic surveys follow a baseline set of minimum standards to ensure a basic level of data quality. You adhere to those minimums, unless someone with authority over the project—such as a governing jurisdiction or the contract—requires more stringent standards. When a jurisdiction or client specifies higher accuracy, additional survey practices, or stricter data handling, those requirements take precedence over the minimum standards. Weather conditions or shortening the survey duration do not automatically change which standards apply; they may affect planning or data collection logistics, but the applicable standard remains the controlling factor.
