ABU DHABI // The greening of Dubai has been captured from space in a satellite photograph published this week.
Centred around Discovery Gardens, the image highlights the lusher communities in red, including Emirates Hills, Jumeirah Islands, and Emirates Golf Club and Springs.
Dubai Media Office on Saturday posted on Twitter the image that Dubai Sat-2 took last year.
The photograph uses false colours to represent certain types of areas. Vegetation is marked in red, bare ground is brown, water is dark blue, and buildings and paved surfaces are light blue or grey.
The image would be useful to public and private entities such as Dubai Municipality and environmental agencies, said Salem Al Marri, assistant director general of scientific and technology affairs at the Mohammed bin Rashid Space Centre.
As the satellite’s onboard camera was limited to capturing images that are 10 kilometres wide, it took five to six passes over Dubai to stitch together a complete picture of the city.
“The image you see is a mosaic which takes months to create,” said Mr Al Marri.
Even though Dubai Sat-2 circumnavigates the globe about 14 times a day, four of which are over the UAE, it takes more than three months to shoot Dubai in its entirety.
The duration will be significantly reduced when the UAE launches its next-generation satellite into orbit.
KhalifaSat, the first satellite built entirely by Emirati engineers, will augment Dubai Sat-2 when it is launched in 2018 and provide more detailed images thanks to a higher-resolution camera.
“If Dubai Sat-2 can tell you how many trees there are in a specific area, you will be able to identify what kind of trees they are with KhalifaSat,” said Mr Al Marri.
With a shelf life of about five years, KhalifaSat will be beaming images well after Dubai Sat-2 is decommissioned in 2020.
Dubai Sat-2’s infrared image is reminiscent of pictures taken of Dubai’s development by a Nasa satellite between 2000 and 2011. Using the same technology, Nasa’s Terra satellite took 12 photographs during that period.
Hundreds of thousands of people viewed the time-lapse video online, which documented the city’s remarkable growth and the creation of the Palm Jumeirah and the World islands.

How to keep control of your emotions
If your investment decisions are being dictated by emotions such as fear, greed, hope, frustration and boredom, it is time for a rethink, Chris Beauchamp, chief market analyst at online trading platform IG, says.
Greed
Greedy investors trade beyond their means, open more positions than usual or hold on to positions too long to chase an even greater gain. “All too often, they incur a heavy loss and may even wipe out the profit already made.
Tip: Ignore the short-term hype, noise and froth and invest for the long-term plan, based on sound fundamentals.
Fear
The risk of making a loss can cloud decision-making. “This can cause you to close out a position too early, or miss out on a profit by being too afraid to open a trade,” he says.
Tip: Start with a plan, and stick to it. For added security, consider placing stops to reduce any losses and limits to lock in profits.
Hope
While all traders need hope to start trading, excessive optimism can backfire. Too many traders hold on to a losing trade because they believe that it will reverse its trend and become profitable.
Tip: Set realistic goals. Be happy with what you have earned, rather than frustrated by what you could have earned.
Frustration
Traders can get annoyed when the markets have behaved in unexpected ways and generates losses or fails to deliver anticipated gains.
Tip: Accept in advance that asset price movements are completely unpredictable and you will suffer losses at some point. These can be managed, say, by attaching stops and limits to your trades.
Boredom
Too many investors buy and sell because they want something to do. They are trading as entertainment, rather than in the hope of making money. As well as making bad decisions, the extra dealing charges eat into returns.
Tip: Open an online demo account and get your thrills without risking real money.

Dubai works towards better air quality by 2021
Dubai is on a mission to record good air quality for 90 per cent of the year – up from 86 per cent annually today – by 2021.
The municipality plans to have seven mobile air-monitoring stations by 2020 to capture more accurate data in hourly and daily trends of pollution.
These will be on the Palm Jumeirah, Al Qusais, Muhaisnah, Rashidiyah, Al Wasl, Al Quoz and Dubai Investment Park.
“It will allow real-time responding for emergency cases,” said Khaldoon Al Daraji, first environment safety officer at the municipality.
“We’re in a good position except for the cases that are out of our hands, such as sandstorms.
“Sandstorms are our main concern because the UAE is just a receiver.
“The hotspots are Iran, Saudi Arabia and southern Iraq, but we’re working hard with the region to reduce the cycle of sandstorm generation.”
Mr Al Daraji said monitoring as it stood covered 47 per cent of Dubai.
There are 12 fixed stations in the emirate, but Dubai also receives information from monitors belonging to other entities.
“There are 25 stations in total,” Mr Al Daraji said.
“We added new technology and equipment used for the first time for the detection of heavy metals.
“A hundred parameters can be detected but we want to expand it to make sure that the data captured can allow a baseline study in some areas to ensure they are well positioned.”
