ABSTRACT

Most globes show information on earth’s surface, but have limited information on the bathymetry. Most undersea features are yet to be discovered, and only 18% of sea surface is mapped in 500m expanse. As GEBCO (The General Bathymetric Chart of the Oceans) has archived several levels of bathymetry data over the world and tries to provide new style of globes. Authors try to classify globes by new scheme and give some vision to expand awareness of both bathymetry data and undersea features. Development of IT technologies expand the scope and information contents so much that cyber or digital globes show the nature of earth better than ever before. We performed SWOT analysis for the commercial use of globes with GEBCO’s bathymetry data set. We discussed educational issues in delivering various classes of globes to the classroom. This article may be a part of outreach activities of GEBCO products.
