SeaZone HydroView API

(2018 update: API DEFUNCT) The service provides marine mapping with configurable images showing depth and topographic characteristics of the world's oceans based on detailed bathymetric data. Requests to the Web Map Tile Service (WMTS) can be embedded to generate images of a global location and the surrounding ocean. Depth and terrain features of the ocean floor are represented as aids to marine navigation, exploration, and research. API methods support submission of a global location, stated in the request as global tile row and column plus zoom level. The API generates and returns a PNG image of the land and ocean floor topography at the specified location, represented as a digital terrain model with shaded relief and depth readings (soundings).
