Digital Globes
Globes would be the spherical version of the map. Their spherical shape enables them to represent the earth perfectly. Globes were forever in used as navigational tools as well as to understand various earths processes and phenomena.
The earliest globes were traced towards the fifteenth century. Like maps, globes also show accurate directions, dimensions, distances, sizes and shapes 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 alterations in the worlds political, social, or environmental conditions.
Digital globes are the ones which use advancements in technology for representing our planet better. They have digital images over and inside the screen that keep changing according to the users requirements. The pictures, derived from satellite images, are created to appear on the screen, that is similar to a picture screen of the 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 aren’t generally meant for commercial applications.
Virtual globes are also digital globes that can be viewed on the computer or 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. Nowadays, the application of virtual globes has become so common that they’re also being fitted in cars in order to make navigation easier for the driver. They can provide detailed information, right down to a streets name.
Another kind of digital globe is the hyperglobe that uses virtual reality to provide spatial effects. These are used for visually depicting certain geographic processes and phenomenon such as the earths 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.
