What type of topography must be shown outside the shoreline on a hydrographic survey?

In a hydrographic survey, understanding the intended use of the survey map is crucial for determining what type of topography should be represented. The topography shown outside the shoreline often provides important contextual information that can affect how the surveyed waterway interacts with its surroundings and is utilized. This may include landforms, elevations, and nearby infrastructure that could impact navigation, environmental conditions, or development plans.

For instance, if the survey is conducted for recreational boating, information about the nearby parks, docks, or facilities becomes essential. Alternatively, for environmental assessments, details regarding coastal vegetation or land use may be prioritized. Such considerations ensure that the final map is relevant and serves its intended purpose effectively, justifying why the topography is determined by the intended use of the survey map. This tailor-fit approach maximizes the utility and applicability of the hydrographic survey data.
