Cartography, uptil some time ago, was the only way of mapping or charting
the globe. Map-reading and map-making is a science, the subtleties of
which might not be available to every lay person. However, commercial-use
maps have been available for a long time now. They are especially useful
for tourists and for drivers. The major drawback of paper 2-D maps was
that they have always been location or area specific. While an atlas, in
theory, is a collection of maps of the whole globe, minute details can
never be divined from them.

Google Earth, the latest software application from the Internet giant
Google, aims to change all this. One of the main features of this
application is that it promises you minutely detailed maps of any
location in this world. Even pictures of man-made building, trees, parks,
mountains are available, if you so desire, in 3-D. It’s a method of
information gathering for any specific location in this world. Google
Earth is quite simply, an extraordinary technological feat. At a stroke,
it has dominated the cartographical business. All you need is a computer
and an Internet connection. Just download the software and you can
discover the world from your desktop.

Google Earth employs the use of satellite imagery, conventional maps and
extremely sophisticated streaming technology to deliver the data to your
desktop. Just type in the location in the software (powered by the award-
winning Google Search) and the map is immediately available to you. Also,
Google Search makes available a list of local facts about your search
object. This technology makes searching for schools, parks, apartment
buildings, even hotels and restaurants anywhere in the world extremely
easy. Not only does it make driving instructions available to you,
location to location, the software also allows you to rotate and full
tilt the maps. This makes it easier for you to explore the urban location
or terrain in 3-D detail.

A great number of customization tools are available for the individual
user. You can bookmark or save your favorite searches and share them with
family and friends. Google Earth also makes use of KML. It is a data
exchange format which allows the user to add their annotations to the map
or the view and also enables the sharing of this information. The map is
formatted in the form of layers-with some features characteristic to each
layer. For example, a specific layer would shoe the geographical
features, while another will make information regarding schools,
hospitals, shopping and airports available to you.
