# MapTiler Ocean schema

The vector tile schema describes how the vector data is organized into different thematic layers and which attribute and values each layer contains. This is useful for writing a map style.

MapTiler Ocean is a tileset that contains contour lines with minimum depth in meters, adjacent polygons with minimum depth for world oceans and seas.

Explore the tileset in the interactive map viewer, check the date of the last update, use it as vector tiles, etc.
