Map categories: Do hydrographic maps primarily convey information about bodies of water, such as coastlines, depths, currents, and related features?

Introduction / Context:
Hydrographic maps and charts support navigation, coastal engineering, environmental monitoring, and resource management. They focus on aquatic features rather than land parcel boundaries.

Given Data / Assumptions:

• Hydrographic products include depths (soundings), contours, shorelines, and hazards.
• They may also show currents, tides, aids to navigation, and seabed characteristics.
• Their purpose differs from cadastral or purely topographic mapping.

Concept / Approach:
These maps prioritize safe navigation and water-related planning. Symbol conventions emphasize bathymetry and maritime information, ensuring mariners and engineers can make informed decisions.

Step-by-Step Solution:

Verification / Alternative check:
Compare a hydrographic chart to a cadastral plat; the former prioritizes depths and marine hazards, confirming the focus on water features.

Why Other Options Are Wrong:

Common Pitfalls:
Reading depths without noting the datum; ignoring tide and current annotations; confusing chart scales.

Final Answer:
Correct
