Watch the Earth Change before Your Eyes

Landscapes/Features of Earth Undergone Dramatic Change


Several of the landscapes and features of the Earth have undergone a dramatic change since 1984. Google has made its prime update to Time-lapse with addition of four years of imagery, big amounts of new data together with a sharper view of the Earth from 1984 to 2016.

Latest images by Google’s Time-lapse application portrays how the features comprising of Alaska’s Columbia glacier and Dubai’s extensive cityscape tend to have drastically progressed in the last 32 years. Its Time-lapse visualisation of Earth, had first been released by Google in 2013, offering the most comprehensive image of our changing planet, made available to the public.

The communicating time-lapse experience permits people in exploring changes to the surface of the Earth like never before from observing the sprouting of Las Vegas strip to the retreat of Alaska’s Columbia glacier. Moreover, it enables user in exploring a variety of compelling locations much further than 1984. For instance, in London, one can make out the progress of the City Airport and the Olympic stadium in Stratford. On zooming in on the Aral Sea it portrays how it has been drying since the 1960s owing to Soviet irrigation programmes.

New Time-lapse Show Sharper View of Planet


If the date is moved to 2007, the volume of the Aral Sea seems to be reduced to about 10% of its original size. For the time being, over the past three decades, Alaska’s Columbia Glacier is observed to have retreated over 12 miles.Another city which has undergone drastic changes since 1984 is New York.

 In comparison to 1984 to 2016, it shows how much progress has been made around the Central Park area and Brooklyn. Programme Manager at Google Earth Engine, Chris Herwig, had commented that `in leveraging the same techniques were used in improving Google Maps and Google Earth back in June, the new Time-lapse showed a sharper view of our planet, with truer colours and less distracting artefacts’.

He further informed that using Google Earth Engine, they had combined over 5,000,000 satellite images, approximately 4 petabytes of data in creating 33 images of the complete planet, one for each year. He added that for the latest update, they had access to more images from the past due to the Landsat Global Archive Consolidation Program together with fresh images from two new satellites, namely Landsat 8 and Sentinel-2.

The 33 new terapixel global images were then encoded into just over 25,000,000 overlapping multi-resolution video tiles, making interactively explorable by Carnegie Mellon CREATE Lab’s Time Machine library, which is a technology in creating and inspecting zoomable as well as pannable time-lapses over space and time.

In order to explore the feature, one could type in the name of a place in the search bar and move the timeline towards the bottom in opting for the year one would prefer to view. Images had been initially collected as part of constant joint mission between the United States Geological Survey –USGS and NASA known as Landsat.

 The Landsat mission’s satellites since the 1970s had been observing the Earth from space. The images have been sent back to Earth and archived on USGS tape drives which is an achievement that is much stress-free with the present digital technology than with analog tape in the 1970s. In order to make this historic archive of earth imagery available online, Google began working with USGS in 2009.

Story behind their names

You have probably heard the story of how you got your name at least once or twice. Well, people are not the only ones that come with interesting naming stories. Founders of companies go to great lengths to come up with quintessential company name, which can at times make or break them.



Google:
The name started as a joke boasting about the amount of information the search-engine would be able to search. It was very first named as"Googol" a word of the number represented by 1 followed by 100 zeros. But later founders-Stanford graduate students Sergey Brin and Larry Page represented their project to angel investor, and from whome they received a cheque made out to "Google'.





Yahoo:


The name was derived by Jonathan Swift and was used in his book 'Gulliver's Travels'. it represents a person who is revolting in nature and action and is barely a human. Yahoo! founders Jerry Yang and David Filo finalised this name because they considered themselves as yahoos.

Micro soft:
Coined by Bill Gates to represent his company that was devoted to MICRO computer SOFTware. Originally named it as Micro-soft, but then the'-' was removed.






Adobe:


Came from the name of the river Adobe Greek that ran behind the house of founder John Warnock.







Corel:



The name was arrieved from the founder's name Dr.Michael Cowpland. The logo stands for COwpland REresearch Laboratory.






Apple computers:
Steve Jobs was three months late in filling a name for the business, because he didn't get any better name for his new company. So one day he told the staff," If I do not get a better name by 5 O'clock today, our company's name will be anything I like." Since at 5 O clock no body came up with a better name, and he was eating an apple at that time (favourite fruit of Steve Jobs), so he kept the name of the company as " Apple Computers".

Cisco:
It is not an acronym as is popularly believed it Short for San Francisco.

Hewlett Packard:


Bill Hewlett and Dave Packard tossed a coin to select whether the company they founded would be called Hewlett-Packard or Packard-Hewlett. And thelosser was Bill, but not Dave








eBay:

The founder of eBay, Pierre Omidyar , had a web consulting company called Echo Bay Technology Group. Echobay.com was already taken when he tried to register it, so he selected the ne name eBay.Com instead.
