One exception to this is the Biological Data Profile of the FGDC. To go along with Bounding Coordinates specifying the extent of the data in the dataset, the profile specifies a mandatory Description of Geographic Extent element to provide a text description of the extent of the study and/or data set.
Calm, peaceful days. The Halcyon is a bird of Greek legend and the name is now commonly given to the European Kingfisher. The ancients believed that the bird made a floating nest in the Aegean Sea and had the power to calm the waves while brooding her eggs.
The Narwhal. The Narwhal, also known as the unicorn of the ocean, is one of the rarest whales in the world. It is very mysterious in its behaviour. The name comes from a Danish word meaning âcorpseâ as the whale has been known to swim with its belly facing the surface and lay motionless for up to long time lapses. They are sallow in color with dark, more speckled specks on the backs of their bodies and lighter shade on their belly.
