Bathymetric chart

A bathymetric chart is a type of map that shows the underwater topography of ocean floors, lakes, rivers, and other bodies of water. Similar to how a topographic map illustrates the elevation and contours of land, a bathymetric chart displays the depth and features of submerged terrain. Key features of bathymetric charts include: 1. **Depth Contours**: These lines connect points of equal depth, allowing users to visualize the underwater shapes and features.
