Digital Globes
Globes are the spherical version of a map.
Their spherical shape allows them to represent the earth perfectly.
Globes were always in used as navigational tools as well as to
understand various earth’s processes and phenomena.
The earliest globes were traced to the fifteenth century. Like maps,
globes also show accurate directions, dimensions, distances, shapes
and sizes of all the countries in the world. Most globe-makers use
high quality geographic research and cartographic abilities to
design globes. They are also updated regularly to take note of any
changes in the world’s political, social, or environmental
conditions.
Digital globes are those which use advancements in digital
technology for representing the earth better. They have digital
images over and inside the screen that keep changing as per the
user’s requirements. The images, derived from satellite images, are
made to appear on the screen, which is similar to a picture screen
of a television. There are also digital raised-relief globes with
clearly defined mountain ranges and water bodies. There are also
celestial digital globes available. However, digital globes are not
generally meant for commercial applications.
Virtual globes are also digital globes that can be viewed on the
computer or any other interface. These may be simple globes used for
classroom teaching, or they can be highly technologically advanced.
Some virtual globes use state-of-the-art technology like satellite
imaging and multiple GIS databases for real-time coverage. Virtual
globes can be online or offline. These days, the application of
virtual globes has become so common that they are also being fitted
in cars in order to make navigation easier for the driver. They can
provide detailed information, right down to a street’s name.
Another kind of digital globe is the hyperglobe that uses virtual
reality to present spatial effects. These are used for visually
depicting certain geographic processes and phenomenon such as the
earth’s inclination, space travel, and satellite technology, through
three-dimensional geoid visualization, animation, and real-time
presentations. These also have interactive cartometric tools for
making the data globally available.
