What does hydrography primarily concern itself with?

Hydrography primarily concerns itself with the mapping and description of water bodies, which is accurately captured by the choice of water mapping. This field involves the measurement and characterization of underwater features, such as depth, shoreline configuration, and the nature of the seabed. Hydrographic surveys provide essential data for navigation, marine construction, resource management, and environmental monitoring. This mapping process includes not only the physical attributes of water bodies but also the dynamic environmental conditions that affect them, making it a critical discipline for safe maritime operations and effective marine resource management.

Other options, while related to water in different contexts, do not align with the primary focus of hydrography. For example, measuring fisheries pertains to biological resources, weather prediction deals with atmospheric conditions, and boat construction involves engineering rather than the survey and mapping of aquatic environments.
