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.

The Roll Of Satellites
One of the largest parts of our news programs is the up to date reports they give us about our recent and upcoming weather events.
Usually news shows will highlight the weather at the beginning of a program and later dedicate a whole segment of the broadcast entirely to the weather report. Accurate weather reporting makes some aspects of our lives a whole lot easier.
In the olden days of weather forecasting, when we had cute little weather girls who were not trained meteorologists, all we got was a large map of the country with those funny looking cutouts of a sun, clouds, raindrops or snow flakes. Those reports were not always very accurate either.
Of course we have come a long way since those days. Today almost all news programs use real meteorologist that are expertly trained in weather related issues, along with satellite imaging to show what our coming weather will be.
Satellites play a large part in the way weather is forecast. The images received from them can show not only the clouds that make our weather, but smoke from wildfires, volcanic ash, oil spills, our coastlines, and so much more. These satellite images are used for all kinds of news reporting besides just our weather forecast. They provide us with important news worthy images from all around the world.
We all know what an important part that satellites play in our lives today. They help us to have better television reception, phone service, and our military uses them also.
They help us to take pictures of things deep in space that normally we could never hope to see. With all these added bonuses of having satellite technology, helping to predict our weather is still one of the most important jobs that they do.
There has been much hurricane and tornado activity that has plagued our planet in recent years. As disastrous as they have been, many lives have been spared because we are now able to clearly see where these storm systems are and track them until they eventually play them selves out.
We can see where they originate, how strong they are, and people are able to make them selves ready.
There are many other factors that satellites play an important part in concerning weather and forecasting it. The best part is knowing we have an eye in the sky helping to protect and forcast our future weather conditions.

Research And Development In Satellite Network And Imaging Systems
Ongoing research and development in advanced technology is just one of the many ways Dish Network attempts to meet the needs of their customers. They provide their subscribers the latest in improved digital satellite television services. This is one of the main reasons there are over 12 million satisfied and happy subscribers. Dish Network often updates their packaging with new channels as well as improves others to maintain, as well as entice new customers, to their growing number in viewing audiences. Recent additions to the Dish Network channel packages include the Bridges television channel, Voom High Definition channel, and the soon to arrive Karaoke channel. It can be said now that Dish Network ignores no one in their line up of diverse digital satellite television programming.
A review of their current programming shows Dish Network now offers over 250 channels of digital satellite television programming with the availability of High Definition or Standard resolution giving you perfect viewing through digital format with little or no imaging being lost. The detail provided by High Definition programming is essential if you are a sports enthusiast or an avid movie fan. It allows you to see more of the surrounding area/location as the camera is pulled back from the objects being filmed, and this advanced technology has changed the way programming is produced. Accompanying sounds are more clearly audible, and you feel like you are physically present on location. In addition to the expanded channel coverage, Dish Network also provides 50 channels of Sirius music, with sports and educational programming, children’s and adult’s programming, 500 commercial-free movies each month, interactive gaming, weather and traffic updates, and international programming. Dish Network offers promotions of free equipment, including several models of Digital Video Recorders, free installation, and some services free for a limited time. Your DVR will enable you to record and store up to 100 hours of programming as well as fast forward, pause (including live programming), and playback, giving you control of replay action. All these services and more are available, and this article will inform you of recent updates to Dish Network’s diverse programming lineup.
Dish Network added Bridges TV to their multi-cultural lineup of channels providing programming relevant to the Muslim culture. There are now more than seven million Muslim Americans, giving this channel the potential of a large audience of Muslims as well as providing a greater understanding of this religion. Bridges TV is now available nationwide, and shows movies, news programs, sitcoms, and children’s programming.
Dish Network’s High Definition digital format allows superior sound and imaging. Voom, a provider of high definition programming no longer in business, sold its satellite to Dish Network to enable Dish Network to provide additional channels showing several original Voom high definition channels. This addition makes Dish Network’s High Definition programming Number One in the nation. Voom’s original channels included RUSH HD, Ultra HD, Animania HD, and others.
Dish Network has a plan to add a karaoke channel to their lineup, and this will be the nation’s first interactive channel of this type. Proposals for this channel include plans to offer a choice of two play lists containing ten songs each that will change twice a month and will differ in genre. Subscribers will be given an opportunity to experience this addition on a trial basis.
These new additions will surely enhance Dish Network’s lineup of programming available to subscribers with ongoing plans for future channel packages.

Satellite Imaging Systems Used By NASA
NASA was established more than 50 years ago and has been a world leader in studies of our home planet. In October 2005 NASA decided to share their series of the stunning 'Blue Marble' images. The satellite photos were divided into 12 calendar months and provided a detailed overview at an entire year in the life of our planet.
Each image took up 10 Gigabytes of hard disk space. To be able to understand how much 10 Gigabytes really is, you can think of that each image consists of 5000 pictures taken with a typical digital camera.
Two years later they are probably still the largest zoomable images ever seen on the Internet. Thanks to advanced zoom technology it is possible for NASA to manage and study our earth by images using any Internet connection.
During the recent years it has become possible to buy expensive products over the Internet. You can buy everything from clothes, cars to expensive furniture. Unfortunately you still have to make a decision for the product based on one or a few images - often in poor quality.
Several studies have shown that the most significant barrier in modern e-commerce is the lack of quality product images - more specific the lack of sufficient image details or resolution. Customers can't "experience and feel" the products in the same way as they were holding them.
The explanation is that high quality images take up a lot of disk space and increase the download time. It is inappropriate to let Internet users wait several seconds for a high quality image each time the user is viewing a product.
Another barrier is the increasing use of mobile devices like PDAs and mobile phones. It is still too hard making a decision for a product on a 240 x 320 pixel display on a mobile phone if the product image is 1680 x 1050 pixels.
But how can it be possible to zoom even large images like NASA's 10Gb satellite images by use of an Internet Connection while webmasters are struggling to limit sizes of their web images?
By combining and re-scaling existing technologies for other purposes and goals, it has become possible to see and almost feel tiny details of any e-Commerce product in the same way as you can study every detail of even large satellite images.
E-Consultant Sonja Jacobsen explains the controversial mix of NASA technology and existing web technology "as a way to move forward in a competitive market" and "almost all e-shops will be able to present their products with zoomable pictures within 2-3 years with similar technologies".

Internet Faxing And Satellite Imaging Systems
Internet faxing need not be restricted to being used for official purposes alone. Online faxing can also be used for personal purposes as well as for people who are on the move constantly. The great thing about this facility is that you can send and receive faxes to and from any part of the world as long as a reliable internet connection has been stabilized. Even better news is that this is much cheaper than a fax machine. Additional advantages are that internet faxing does not involve hassles such as phone connection, fax machine, paper etc.
In brief, here are some of the advantages in using internet faxing:
Initially, the cost of setting it up is very minimal. As the traditional fax machine is required to send or receive faxes, a phone line does not become a necessary pre requisite; hence saving a whole load of money on phone bills as well as thermal paper that is usually needed for fax machines.
Internet faxing can save money both in terms of long term and short term savings. Depending on the usage, the sign up fees can be anywhere from $20 to just $5 per month.
It can be accessed anywhere, provided an internet connection is available. As the fax service is web based, a person need not confine themselves to an office or home in order to send or receive faxes. It is the ideal solution for professionals, who travel a lot and are always on the move such as real estate agents, sales personnel etc.
Be it one small office or a multi storey building of many different offices; or even a home, internet faxing is compatible to any scale of business. If your faxing demands are large, you could even get discounted rates from the providers. This in itself would account for substantial savings in addition to meeting all your faxing needs.
The best part of internet faxing is that it is very cost effective. Since this makes use of the internet to send and receive faxes, all that you need to do is sign up for the service with a service provider on a monthly basis and enjoy the many benefits it has to offer, convenience being the primary objective.
There is also an option of creating an account with the service provider and logging into your account when you need to send or receive a fax. Also an added advantage with this is that you can store your faxes. Service providers offer a wide variety of packages, in which you have the option of personalizing your package by choosing additional features, customized for your needs.
