Queensland’s floods are so huge the only way to track them is from space

Linlin Ge, UNSW

Many parts of Queensland have been declared disaster zones and thousands of residents evacuated due to a 1-in-100-year flood. Townsville is at the epicentre of the “unprecedented” monsoonal downpour that brought more than a year’s worth of rain in just a few days, and the emergency is far from over with yet more torrential rain expected.

Such monumental disruption calls for emergency work to safeguard crucial infrastructure such as bridges, dams, motorways, railways, power substations, power lines and telecommunications cables. In turn, that requires accurate, timely mapping of flood waters.

For the first time in Australia, our research team has been monitoring the floods closely using a new technique involving European satellites, which allows us to “see” beneath the cloud cover and map developments on the ground.

Floods don’t occur randomly, so why do we still plan as if they do?

Given that the flooding currently covers a 700km stretch of coast from Cairns to Mackay, it would take days to piece together the big picture of the flood using airborne mapping. What’s more, conventional optical imaging satellites are easily “blinded” by cloud cover.

But a radar satellite can fly over the entire state in a matter of
seconds, and an accurate and comprehensive flood map can be produced in less than an hour.

Eyes above the skies

Our new method uses an imaging technology called “synthetic aperture radar” (SAR), which can observe the ground day or night, through cloud cover or smoke. By combining and comparing SAR images, we can determine the progress of an unfolding disaster such as a flood.

In simple terms, if an area is not flooded on the first image but is inundated on the second image, the resulting discrepancy between the two images can help to reveal the flood’s extent and identify the advancing flood front.

To automate this process and make it more accurate, we use two pairs of images: a “pre-event pair” taken before the flood, and a “co-event pair” made up of one image before the flood, and another later image during the flooding.

The European satellites have been operated strategically to collect images globally once every 12 days, making it possible for us to test this new technique in Townsville as soon as flooding occurs.

To monitor the current floods in Townsville, we took the pre-event images on January 6 and January 18, 2019. The co-event pair was collected on January 18 and January 30. These sets of images were then used to generate the accurate and detailed flood map shown below.

The image comparisons can all be done algorithmically, without a human having to scrutinise the images themselves. Then we can just look out for image pairs with significant discrepancies, and then concentrate our attention on those.

Our technique potentially avoids the need to monitor floods from airborne reconnaissance planes – a dangerous or even impossible task amid heavy rains, strong wind, thick cloud and lightning.

This timely flood intelligence from satellites can be used to switch off critical infrastructure such as power substations before flood water reaches them.

Plinky Prompt – My Best Friend Rebecca: Why She is My Best Friend

My best friend is not around anymore. I would probably have not written about her tonight, except I have been thinking about her throughout the day. I have just felt a need to write something about her tonight.

My friend Rebecca died over two years ago now, but the memory of her continues fresh in my mind and in my heart. I miss her so, so much. I think of her often – there may be a smile, sometimes a quiet laugh, often there will be tears. Her place has never been taken by another & her place will always be her place.

I think this far down the track I am yet to say goodbye… I don’t want to say goodbye. I still hope that she is just around the corner and that we can continue where we left off. One more conversation, one more embrace, one more look – one more so much. But that would still not be enough.

I knew her – she knew me. We could talk with openness. We just went together so well. Her thoughtfulness, her heart, her being – Rebecca. That is why she was my best friend. She was Rebecca – she is Rebecca. There is no one like Rebecca to me.

I miss her so.

Church of England moves towards ordaining women

Over the weekend, the Church of England introduced draft legislation putting the country’s Anglican communion on the fast track to allowing women’s ordination, reports Catholic News Agency.

On Saturday, May 8, the Church of England’s revision committee published a 142-page review in favor of draft proposals that support women being consecrated as bishops and priests.

According to Reuters, the church’s revision committee also proposed safeguards for more traditional parishes who have expressed opposition to ordaining women, including the right to request that a male bishop perform blessings and ordinations. However, the committee proposals did not meet the requests by these parishes for new dioceses or a special class of bishops.

“After much discussion the Committee rejected proposals aimed at fundamentally changing the approach of the legislation for those unable to receive the ministry of female bishops,” wrote Church of England officials in a statement Monday.

The draft proposals will now go forward for debate at the Church’s General Synod, in July in York, Northern England. If passed, the Church of England will hold the same position on female ordination as the Anglican Communion in the United States and New Zealand.

Monday’s statement also clarified that the “earliest that the legislation could achieve final approval in Synod (when two-thirds majorities in each of the Houses of Bishops, Clergy and Laity will be required) is 2012, following which parliamentary approval and the Royal Assent would be needed.”

The statement added that “2014 remains the earliest realistic date when the first women might be consecrated as bishops.”

This move is likely to increase interest among traditionalist Anglicans in the Pope’s recent invitation for Church of England members to become Catholic. Last November, the Holy Father released “Anglicanorum coetibus,” a motu propio which offered Vatican guidelines for Anglican groups to enter into communion with the Catholic Church.

The Sunday Telegraph in Britain reported on May 2 that several Anglican bishops recently met with Vatican officials to discuss the process of converting to Catholicism.

Despite the Archbishop of Canterbury Rowan Williams reportedly urging them not to leave the Church of England, several bishops are looking to break from the Anglican Communion over their opposition to the introduction of women bishops and priests.

According to the British paper, Bishops John Broadhurst, Keith Newton and Andrew Burnham, from the Dioceses of Fulham, Richborough and Ebbsfleet respectively, all met with senior Vatican officials last week.

Muslim Relatives of Sudanese Christian Woman Pursue Her, Son

Native of Khartoum lives in seclusion in Egypt as brother, ex-husband hunt for her.

NAIROBI, Kenya, December 10 (CDN) — A Sudanese woman who fled to Egypt after converting from Islam to Christianity is living in secluded isolation as her angry family members try to track her down.

Howida Ali’s Muslim brother and her ex-husband began searching for her in Cairo earlier this year after a relative there reported her whereabouts to them. While there, her brother and ex-husband tried to seize her 10-year-old son from school.

“I’m afraid of my brother finding us,” said the 38-year-old Ali, who has moved to another area. “Their aim is to take us back to Sudan, and there they will force us to return to the Islamic faith or sentence us to death according to Islamic law.”

Ali said she divorced her husband, Esam El deen Ali, because of his drug addiction in 2001, before she converted to Christianity. She was living with her parents in Khartoum when she began seeing visions of Christ, she said.

“In 2004, I started to see a vision of Christ speaking to me,” she told Compass. “When I shared it with my friend, who is a Muslim, she said that she used to hear these things from Christians.”

This comment spurred her to seek out a Christian friend from southern Sudan, who told her about Jesus Christ and prayed with her.

“After that time, I begun to see more visions from Christ saying, ‘He is Christ the Good Shepherd,” she said.

Fearing that relatives might discover she was a Christian, in 2007 she escaped with her then-8-year-old son. Previously the family had tried to stop her from leaving on grounds that she should not travel unescorted by an adult male relative, and because they disapproved of her divorce.

“They destroyed my passport, but through the assistance of a Christian friend, I acquired a new passport and secretly left,” she told Compass by e-mail.

Her peace in Egypt was short-lived; earlier this year, while Ali secretly attended church as she stayed with a Muslim relative in Cairo, the relative found out about her conversion to Christianity and notified her brother and ex-husband in Sudan.

They arrived in Cairo in July. She had found lodging at All Saints’ Cathedral, an Episcopal church in Cairo that houses a refugee ministry, but as it became clear that her brother and ex-husband were searching for her, refugee ministry officials moved her and her son to an apartment.

Ali said her brother and ex-husband sought to kill her for apostasy, or leaving Islam – with the support of relatives back in Sudan and others in the community, members of the Shaingia tribe who practice a strict form of Islam.

“Life became very difficult for me,” she said.

The Rev. Emmanuel S. Bennsion of All Saints’ Cathedral confirmed that Ali’s ex-husband and brother were acting on a tip from one of Ali’s relatives when they came searching for her in Cairo. They went to her son’s school to take him back to Sudan. It was a Christian school, and the director refused to hand the boy over to them, Bennsion said.

“Since that time, she has started hiding and become afraid,” Bennsion told Compass.

Ali had received financial support from family in Sudan through the relative in Cairo who notified her family of her conversion; that support has since vanished.

Fearing forcible repatriation to Sudan, Ali tried to go to Israel; Egyptian authorities arrested her at the border and jailed her for two months. During that time, she said, her son was put in an Islamic children’s home. A Muslim family had adopted him, but she was able to win back custody after leaving jail in October.

“We have stopped going out of the apartment or even going to church,” she said. “My son can no longer go to school daily as before. We cannot live our lives as before. I cannot now participate in the Bible study or fellowships – I’m now depending only on myself for growing spiritually, and for prayer and Bible study.”

She said her only hope for living her faith openly in Christian community is to secure asylum to another country that guarantees religious freedom.

Special Investigations Team Sought in Orissa Violence

Acquittals increasingly surpass convictions due to shoddy or corrupt police investigators.

NEW DELHI, December 7 (CDN) — Christian leaders in India have called for a special investigations team to counter the shoddy or corrupt police investigations into anti-Christian violence in Orissa state in August-September 2008.

Of the 100 cases handled by two-fast track courts, 32 have been heard as of Nov. 30, resulting in 48 convictions and more than 164 acquittals. A legislator for the main Hindu extremist party has been exonerated “for lack of evidence” in six cases, most of them involving murder charges. The number of cases registered total 787.

“Christians are extremely shocked by this travesty of justice in Orissa,” attorney Bibhu Dutta Das told Compass.

The government of Orissa set up two fast-track courts in Kandhamal district headquarters for cases related to the violence that began in August 2008 after the killing of Swami Laxmanananda Saraswati and four of his disciples in Jalespetta on Aug. 23, 2008. The chief minister of Orissa state has admitted that Hindu extremist umbrella group Sangh Parivar was involved in the anti-Christian violence (see sidebar below), and Christian leaders have said they are increasingly concerned over verdicts in the fast-track courts based in Phulbani.

Among those exonerated “for lack of evidence” was Manoj Pradhan, a legislator from the Hindu extremist Bharatiya Janata Party (BJP), who was acquitted of murder on Nov. 24. He was accused of killing Trinath Digal of Tiangia village on Aug. 25, 2008.

Thus far, Pradhan has been cleared in six of 14 cases against him.

“Manoj Pradhan has been let off in all the major cases against him, mostly murder cases, for lack of evidence,” attorney Das told Compass. “Now only small cases of arson remain against him.”

Attorneys said acquittals have resulted from police investigations that were intentionally defective to cover up for Hindu extremist attackers. In many cases, for example, police have fraudulently misrepresented the ages of suspects so they would not match with those denoted in the victims’ First Information Reports, leaving the court no option but to let the alleged culprits go.

Nine people were convicted, and five suspects, including Pradhan, were acquitted “for lack of evidence” on Nov. 18 for burning the house of Ratha Nayak in Mlahupanga village, Kandhamal on Aug. 27, 2008. Those convicted were sentenced to four years of prison and fined 3,500 rupees (US$75) each.

In a previous case, witnesses had testified to the involvement of Pradhan in the kidnapping of Kantheswar Digal – subsequently murdered on Aug. 25, 2008 – in Sankarakhole village, Phulbani district, but their testimony failed to convince the court to condemn the BJP politician.

Pradhan was arrested and jailed in October 2008 and was elected as BJP Member of the Legislative Assembly from the G. Udayagiri constituency while in jail.

On Nov. 24, Judge C.R. Das acquitted six suspects: Budhdeb Kanhar, Purander Kanhar, Gadadhar Kanhar, Sudhir Pradhan, Ajibana Pradhan and Dadhi Mallick. They were accused of killing Meghanad Digal and his wife Priyatama from Dutukagam village, Tikabali on Sept. 25, 2008.

Judge S.K. Das sentenced 12 persons to four years of prison along with a fine of 2,000 rupees (US$43) each on Nov. 28 for torching houses and shops at Sirtiguda village, under Nuagaon police jurisdiction, on Sept. 13, 2008.

Indo-Asian News Service reported that on Nov. 30 Sanjeev Pradhan was convicted of torching the house of Shravan Kumar Digal of Penagari village on Aug. 25, 2008. Sanjeev Pradhan was sentenced to prison for five years and fined 7,500 rupees (US$160).

Special Investigation Team Sought

Christian leaders are calling for a special investigation team like the one created after communal violence wracked Gujarat state in 2002.

“The need of the hour is a special investigation team, for the investigations of the Orissa police have caused doubts,” attorney Das said. 

He added that the cases should be transferred out of Kandhamal, as Christian leaders feel justice cannot be served in the district’s Hindu extremist atmosphere.

Many of the Christians displaced as a result of the violence have yet to return to their villages. The archbishop of Bhubaneswar-Cuttack, Raphael Cheenath, told media that out of 50,000 people displaced, about half have returned, “but they are facing housing problems. The state government should take it up earnestly.”

Dr. John Dayal of the All India Christian Council stated in a Dec. 4 report that “several thousand of the 50,000 Christian refugees are still to return home. Many cannot, as they have been told they have to convert to Hinduism before they will be accepted in the villages. The threats and coercion continue till today.”

He added that most of the more than 5,000 houses destroyed in December 2007 and August-October 2008 mayhem have yet to be rebuilt.

Attorney Das told Compass many of those who fled their village fear returning home.

“It is true that in many cases, the pre-condition of converting to Hinduism and facing violence if they do not has been the factor that has prevented the people from returning to their homes,” he said. “The fear of being attacked again has also stopped many from going into their villages. The government has not been very successful in instilling trust in the Christian community that such incidents can be prevented in the future.”

Orissa police yesterday arrested a man accused in the rape of a nun during the violence in Kandhamal. Gururam Patra was reportedly arrested in Dharampur.

He was accused of leading a mob that attacked the nun at on Aug. 25, 2008. Police have so far arrested 19 people in the incident, with another 11 still at large. The 29-year-old nun has told police she was raped and paraded naked by a Hindu extremist mob, and that officers only stood by when she pleaded for help.

SIDEBAR

Official Names Hindu Nationalist Groups in Orissa Violence

NEW DELHI, December 7 (Compass Direct News) – The ruling party of Orissa state, which labelled last year’s mayhem in Kandhamal district as “ethnic violence,” has publicly admitted that Hindu nationalist groups were behind the killings and arson of Christians and their property.

“It is learnt from the investigation into the riot cases that the members of the RSS [Rashtriya Swayamsevak Sangh], the VHP [World Hindu Council] and the Bajrang Dal were involved in the violence that took place last year,” Orissa Chief Minister Naveen Patnaik told the state legislative assembly last month.

Patnaik, in response to a question by a member of the Communist Party of India, also disclosed that police had arrested 85 people from the RSS, 321 members of the VHP and 118 Bajrang Dal members in the attacks. He said that only 27 members from these groups were still in jail.

The others were either bailed out or acquitted for lack of evidence, which Christians say is due to shoddy or corrupt investigation by police and prosecutors (government attorneys).

Soon after violence in Kandhamal broke out in August 2008, Patnaik blamed it on “conflict of interest” between Dalits (people at the bottom of the caste hierarchy in Hinduism and formerly known as “untouchables”) and tribal people.

National media speculated that Patnaik was seeking to deflect attention from the Bajrang Dal, which had been accused of the attacks on the Christians. The Bajrang Dal (Army of Hindu God Hanuman) is the youth wing of the VHP, which is seen as part of the RSS family.

Local Christians had suspected the role of the RSS and related outfits since the violence began on Aug. 24, 2008 – one day after Hindu nationalist leader Laxmanananda Saraswati was killed by Maoists (extreme Marxists) and RSS members blamed Christians for it.

The RSS is a Hindu nationalist conglomerate whose political wing, the Bharatiya Janata Party (BJP), was part of the ruling coalition during the 2008 eruption of the violence that killed more than 100 people, mostly hacked to death or burned alive, and incinerated more than 4,500 houses, over 250 churches and 13 educational institutions.

Patnaik’s party, the Biju Janata Dal (BJD) broke up its 11-year-old alliance with the BJP in March 2009, a month before state assembly and national elections were held. The BJD, which fought the two elections alone, won a majority in the state assembly and most seats in parliament from the state.

It was only after the coalition’s break-up that the BJD began to hint at the culpability of the RSS and related groups.

“It was important to break up with the BJP, because I don’t consider them healthy any longer for my state after Kandhamal [violence] – which I think is very apparent to everyone,” Patnaik told CNN-IBN, a private TV news channel, on April 19.

A state government-constituted panel, the Justice Mohapatra Commission of Inquiry, is probing the Kandhamal violence but has yet to issue its final report.

Meantime, a report of another panel, the Justice M.S. Liberhan Commission of Inquiry, said that top leaders of the BJP, the RSS, the VHP and the Bajrang Dal “meticulously planned” the demolition of the 17th century Babri Mosque 17 years ago.

More than 2,000 people were killed in communal violence across the country following the demolition of the mosque on Dec. 6, 1992. The incident polarized voters along religious lines and subsequently contributed to the BJP’s rise in Indian politics.

The Liberhan report, presented to parliament on Nov. 25, indicted several Hindu nationalist leaders, including former Prime Minister Atal Bihari Vajpayee, current Leader of Opposition in the People’s House L.K. Advani, VHP leader Ashok Singhal and former RSS chief K.S. Sudarshan.

Observers said the indictment of extreme Hindu nationalists, however, has come too late, as the BJP no longer seems to be powerful at the national level.

Report from Compass Direct News 

AUSTRALIA: CYCLONE HAMISH UPDATE – 8th March 2009

Cyclone Hamish is continuing to track parallel down the Queensland coast and thus far there have been no reports of injuries or major damage. Damaging winds can now be expected between Mackay and Bundaberg with the storm currently located to the north-east of Mackay.

The cyclone has been downgraded from a category 5 cyclone to a category 4 cyclone. The storm is massive and will still cause major damage should it cross the coast on Tuesday as forecast. The cyclone is generating winds of up to 260 km per hour.

Lady Elliot, Heron and Fraser Islands are all being evacuated as the cyclone heads in their direction. It is thought that the Hervey Bay area is the likely area the cyclone will fully impact on, with its remnant reaching possibly Brisbane.

CRIME CRACKDOWN: Councils to DNA Test Dog Droppings

Yes you read the title of this post correctly – there is a major crime wave in Sydney that warrants a massive redirection of funds. According to news reports today, a number of Sydney local governments are keen to test dog droppings with DNA technology in order to crackdown on owners who refuse to clean up after their dogs.

Dog owners are required to pick up dog droppings here and this is generally done by disposable gloves (or the like) and a plastic bag that dog owners take with them when walking the dog. The owners are then required to dispose of the waste in a responsible manner. However, it seems that a number of dog owners just can’t bring themselves to clean up after their dogs – perhaps these owners are simply above doing this type of thing or maybe they can’t stomach doing so.

Dogs are currently required to have an identification microchip installed (for want of a better word) and under the proposed DNA testing scheme, they would then also be DNA tested so that their records are kept on a database. With this done, dog droppings could be DNA tested and the results cross referenced with the database. The owners of offending dogs would then be easy to track and revenue increased for local councils (oops, did I suggest that this was a revenue raising scheme) through the issue of a fine.

 

 

 

RUNAWAY TYRE … The Perfect Landing

While having a look at another Blog I saw a link to this YouTube video which I thought my readers may enjoy (are there any out there by the way?).

Let me set the scene – it is a car race and one of the cars looses a wheel which begins to travel by itself down the race track. It could be a disaster, but as you’ll see it is far from it.

Enjoy.

THE MARK OF THE BEAST AND CATTLE TAGS

According to a Blog entry by David Kravets, community farmers in the USA are becoming quite concerned about cattle tags because they are the ‘mark of the beast,’ a reference to symbolic language used in the Book of Revelation.

The tags, as in Australia, are used to track cattle and can be used for ensuring meat quality, keep a check on the spread of disease, etc.

The anti ‘Mark of the Beast’ farmers have filed a suit in the U.S. District Court for the District of Columbia and are quite serious about not complying with cattle tagging laws (National Animal Identification System). The lawsuit was filed by a group called the ‘Farm-to-Consumer Legal Defense Fund,’ which has some 1 400 members.

Should the farmers fail to win the lawsuit, many are expected to quit farming rather than comply with something which would see them (according to their beliefs) embrace the Beast of Revelation.

This sort of thing should be of no surprise when dealing with Christians who have embraced the Premillennialist viewpoint of end times eschatology. Those who hold to such teachings see the mark of the beast in any number of modern technological gadgetry and computer generated codes. They see the mark of the beast in any sort of identification card or chip, in barcodes, etc.

In short, the chief error of the Premillennial viewpoint is the literal understanding of the figurative language of Revelation and other similar writings found in such books of the Bible as Daniel and Ezekiel.
