Which term describes the science and art of representing water features on maps?

• A. Photogrammetry
• B. Hypsography
• C. Bathymetry
• D. Hydrography

Answer: (D)

Representing water features on maps is hydrography. This field blends scientific methods with cartographic craft to describe and depict oceans, rivers, lakes, coastlines, depths, tides, and related navigational information on charts and maps. It encompasses both data collection about water bodies and the way those features are illustrated for use on maps. Bathymetry focuses specifically on measuring water depth, not the broader depiction of water features. Hypsography deals with land elevations and topography, while photogrammetry is a method of deriving measurements from photographs to create maps. Therefore, hydrography is the term that captures the science and art of mapping water features.
