The British Oceanographic Data Centre (BODC) is a national facility for maintaining and distributing data concerning the marine environment. They provide several web services for implementing this data, including the GEBCO Web Map Service.
This service provides access to the General Bathymetric Chart of the Oceans' (GEBCO) global gridded bathymetric data set, enabling users to access geo-referenced underwater topographic maps over the internet. These can be viewed in a web browser or a geographic information system and incorporated with other web applications using REST (HTTP GET) calls.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
