Hydrographic Survey:

A hydrographic survey involves the measurement and description of physical features of water bodies, such as oceans, seas, lakes, and rivers. The primary objectives include:

• Mapping Water Bodies: Determining the depth, shape, and underwater features of water bodies, including the seabed.
• Navigation Safety: Identifying hazards such as reefs, rocks, and shipwrecks to ensure safe navigation for vessels.
• Resource Management: Providing critical data for managing marine resources like fisheries, oil, and gas reserves.
