Australia, topographic map. Highlands and lowlands of the continents are shown as ridges and flat areas. Southeast Asia (top left), New Zealand (lower right) and Antarctica (bottom right, white) are also seen, along with the South Pacific Ocean and its various islands (upper right). The seabed depth varies from shallow (light blue) on the continental shelves to deep ocean basins (dark blue). Topographic and bathymetric data is usually gathered by using aerial and satellite imagery combined with radar and sonar mapping. The satellites in this case were NOAA's POES satellites.
