What’s free is the most expensive | Lee Yee

Last week, Carrie Lam announced that the Central government will support Hong Kong’s fight against the epidemic in several large initiatives, including universal screening, earmarking AsiaWorld Expo as a holding treatment facility, and the construction of the makeshift hospitals, all cost to be borne by the Central government.

Such “good deeds”, shouldn’t society respond with great enthusiasm? But according to Carrie Lam, there are voices in society trying to divide the public and the government, “Every time (the government) does something, it will be discredited by some people with conspiracy theories,” and asked the media to “join (the government) in the call on citizens to participate in testing.”

Distorting facts is what discrediting means, but some facts cannot be denied, for example:

● Nationally-approved testing personnel have been exempted by the government from the requirement to register for medical laboratory work in Hong Kong. China’s BGI (formerly Beijing Genomics Institute) will process the samples from the citywide screening. Its chemists are not registered in Hong Kong.

● BGI is a listed company in Shenzhen responsible for collecting and analyzing the “national gene bank”.

● In July 2020, two companies under BGI Group were included in the sanctions list by the U.S. Department of Commerce for “suspicion of forced collection of DNA of Uyghurs and other Muslim minorities for research in order to suppress Uyghurs.”

● On Aug. 14, a multinational biotechnology company filed a lawsuit with the High Court against BGI, accusing it of infringing upon a gene sequencing kit patent. GBI’s trustworthiness is in line with the level of many other Chinese companies.

● Some medical professionals believe that under the current condition of border and market non-closure, doing universal screening alone is not helpful. The public’s acceptance of testing increases the risks.

Faced with these facts, it’s evident to the public how many will be tested voluntarily. Moreover, the effectiveness of screening has been questioned by regions who’ve successfully stopped the spread of the virus, including Taiwan.

Because of China’s support, Hong Kong is not paying. As such, Carrie Lam and her cabinet have relentlessly professed their gratitude towards the Central government.

Japanese writer Isaka Kotaro said, “Nothing is more expensive than free.” A few years ago, Chinese entrepreneur Jack Ma also repeated the same thing, “free is the most expensive.” Why the most expensive? Because the price you pay is time, privacy, health, freedom, these seemingly intangible things, our most precious wealth. From the collected samples, a chemist can obtain one’s DNA, some very sensitive and personal privacy information.

We would rather pay for what we need, rather than the free things given. If the three anti-epidemic initiatives were paid for by the government, it will be necessary to get LegCo to approve the funds. In the process, at least the government and BGI or other institutions must go through negotiations that must be disclosed, rather than operating within a black box. If the three initiatives were to invite bids from Western countries, there will not be viral conspiracy theories or “smearing” remarks on social media.

The Carrie Lam regime has been accusing the United States and other Western countries of adopting “double standards” for Hong Kong in recent years. For example, the US police force also used violence against the protesters, many countries have national security laws, and other countries have postponed elections, etc., why only criticize and sanction Hong Kong?

Regarding the behaviors of people, society, and countries, we should adopt the same standards for judging and commenting, but the premise is that the other party is a person, society, and country with certain standards. We respect people from anywhere, but that does not equate respecting people who have no standards in words or deeds, and do not respect themselves. Many countries have national security laws, but behind which most countries have legislative procedures that are fully authorized by public opinion, and are restricted by the judiciary and independent media and public opinions. How is a national security law with absolute powers without checks and balance comparable to those in these other countries? Many countries allow a certain degree of police violence on protesters, but there are other mechanisms to restrict them, such that improper police violence will be followed by legal consequences.

Under autocracy, power is the single most almighty thing, accompanied by no “standards” whatsoever, whether professionally, or behaviorally of those in power and their people. Autocracy does not comply with universal standards. The standards used on those people and regimes with standards cannot be adopted on those people and regimes that do not. Facing those without standards, the natural human instinct is distrust.

What Are Ground Control Points (GCPs) and How Do I Use Them?
A Guide to Using Ground Control Points with Drone Mapping Software
If you work with drone mapping software, you’ve no doubt heard talk of ground control points (GCPs). Used often in the surveying industry, as well as in virtual design and construction, GCPs greatly increase the global accuracy of drone maps. Although they are not necessary in every situation, GCPs are a vital tool for precision mapping. But what exactly are ground control points? And how do you go about using them correctly?

To help crack the code on ground control points, we’ve put together this short guide to using GCPs with drone mapping software.

What Are Ground Control Points?
So what exactly are ground control points? Ground control points are large marked targets on the ground, spaced strategically throughout your area of interest. If you use ground control points with your aerial map, you first need to determine the RTK GPS coordinates at the center of each. (We’ll explain how to do this a little later.) The ground control points and their coordinates are then used to help drone mapping software accurately position your map in relation to the real world around it.

It might be helpful to think of your GCPs as a series of thumbtacks placed on your drone map. Because the drone mapping software knows the exact location of each of these “thumbtacks”, it can reference their locations when it matches up all of the other points on the map.
When and Why Are GCPs Important?
When used correctly, ground control points greatly improve the global accuracy of your drone map. That is to say, they help ensure that the latitude and longitude of any point on your map corresponds accurately with actual GPS coordinates. This is important in situations where precision mapping and true global accuracy are needed. As we mentioned above, surveying companies generally use GCPs, because a high level of global accuracy is important in most of the work that they do. Virtual design and construction is another sector that often requires this level of precision drone mapping.

Landpoint, a surveying company based in Louisiana, uses ground control points when creating drone maps used for topographical surveying. Using GCPs on an 85-acre map, their team conducted an accurate aerial survey, saving over 80 man hours compared to traditional land survey methods.

Each drone mapping project is unique, and not all projects require a high level of global accuracy. Because of this, it is important to assess each project individually before you decide to take the extra step of using GCPs. But generally speaking, projects like geo-referenced overlays, design documents and land title surveys benefit from the use of ground control points. In an upcoming post, we’ll take a deeper look at which types of projects are best suited for using GCPs.

How to Construct a Ground Control Point
There is no one right way to make a ground control point. One important thing to remember is that the GCP must be easily visible in your aerial imagery. This is achieved by using high-contrast colors and by making sure the ground control point is large enough to be seen from your particular flight altitude. We generally recommend flying at 300 feet with a frontlap and sidelap of 70/75 when using ground control points. Keep in mind that this may change dependent upon the area you are mapping. Learn more by reading our recent post about mapping accuracy and reviewing our GCP support documents.

A number of companies do sell pre-made, portable ground control points. However, many drone users simply fashion their own.
This well constructed GCP was spray painted onto the concrete using a stencil. Notice that the marker is large enough to be visible from far away. A center mark helps eliminate any confusion as to where the center point is located.

If you’re unable to mark GCPs with paint, there are a variety of low-cost ways to make markers with items available from any local hardware store. The weather-resistant rubber and vinyl markers seen above end up costing about $5 each and are very durable.

Measuring the Location of Your GCPs
As we mentioned above, it is important to measure the GPS coordinates at the center of each ground control point. To do this, you need either a Real Time Kinematic (RTK) or Post Processing Kinematic (PPK) GPS receiver. Trimble and Leica products are commonly used for high-accuracy GPS measurements. New, lower-cost alternatives have recently come onto the market as well. Hiring a surveyor to measure the location of your ground control points is also an option.

Do not use a phone or tablet to measure the location of your ground control points. The accuracy of these devices is very similar to that of a drone’s onboard GPS system and will not deliver precise results. Instead, use one of the previous methods listed above, such as an RTK or PPK GPS receiver.

Best Practices for Using Ground Control Points with Drone Mapping Software
Of course, if you use ground control points with drone mapping software, it is important to use them correctly. Follow these best practices to help ensure your GCPs serve their intended purpose and improve the accuracy of your map.

Use a minimum of 4 large GCPs: DroneDeploy requires a minimum of 4 ground control points. Each should measure at least four feet. No more than 10 are usually needed for larger maps.

Evenly distribute your GCPs on the ground: For most maps of moderate size, we recommend 5 GCPs, one located near each corner and one located in the center, as pictured above. Also, make sure GCPs are spaced far enough apart, to avoid confusion. As a general rule, if you can see more than one GCP in an image, they are too close together.

Create a buffer zone around your map’s perimeter: We recommend a buffer zone between the edges of your map and any ground control points. This ensures there is enough image coverage to carry out reprocessing. The size of your buffer zone should be somewhere between 50–100 feet, depending on the overlap of your flight. A higher overlap produces more images and generally requires less buffer zone.

Be aware of elevation changes: If the area being mapped has noticeable elevation changes like hills, mines and valleys, make sure to place at least one ground control point on each of the different major elevations.

Make sure your GCPs are unobstructed: Visual obstructions like overhangs, snow, shade or glare make ground control points difficult to identify on your drone map.

Know Your EPSG code: Before processing your map in DroneDeploy, you must enter the EPSG code that relates to your GPS measurements. Choose your EPSG code by modifying the settings of your GPS measurement device. In most cases, we recommend using WGS84 (EPSG: 4326).

" justice for wildlife "
ร่วมเป็นเสียงขอความยุติธรรม ไม่ให้การสังหารโหดเจ้าเสือดำ
สายพันธุ์ที่ใกล้สูญพันธุ์แห่งป่าทุ่งใหญ่นเรศวร นั้นเงียบหายไป

#เชิญเซฟภาพcoverเปลี่ยรใช้กันได้เลยครับ #ทวงความยุติธรรมให้เสือดำ

This is the face of wildlife crime in Thailand. This is a Criminal, and if justice follows course, this man should serve time for the crime !
.
This man is also one of the most wealthy persons in Thailand, being the President and CEO of a prominent infrastructure construction company.
.
Very little attention has come to this newsworthy event, but at least the man has been charged with wildlife offenses. Let's see what money and power can buy ? Will Law stand fast and protect the endangered Wild ? Or will corruption be fostered and influence pampered ?
.
KANCHANABURI — A construction company mogul and three other men were charged Tuesday with poaching a leopard, panther and other wildlife in a sanctuary.
.
Premchai Karnasuta, the 63-year-old president of Italian-Thai Development and three others were charged with six poaching-related crimes after they were caught 2am on Monday in the Thungyai Naresuan Wildlife Sanctuary with animal carcasses and hunting weapons.
.
“In that area, camping is prohibited, but we found four tourists so we searched them. We found lots of weapons and wild animal carcasses,” Thammarat Wangsopha, the sanctuary’s director said Tuesday.
.
Authorities found two rifles, a double-barrelled shotgun, various bullets, the body of a Kalij pheasant, a muntiacini deer carcass, a skinned and salted black leopard and a black panther skull in the camp.
.
The four men were sent to the local police station where they were charged with hunting animals in a wildlife sanctuary, which carries a maximum sentence of five years and a fine of 50,000 baht; illegally hunting protected species and possesing caracasses of protected species, punishable by four years in jail and a 40,000 baht fine.
.
They were also charged with weapons-related charges and poaching, punishable by up to 10 years in prison and a 200,000 baht fine.
.
The other three men arrested and charged with Premchai were Yong Doadkrua, 65, Natee Riamsaen, 43, and Thanee Thummat, 56.
.
The sanctuary director said the construction CEO claimed he was the guest of a wildlife official.
.
“Premchai is claiming that he’s the guest of Kanchana Nittaya, the director of the Wildlife Conservation Office,” Thammarat said. “He said he submitted documents asking for permission. But by due process those documents are supposed to be sent to the regional wildlife offices.”
.
Thammarat denied the claim.
.
“I insist that I have not seen any such document,” Thammarat said. “Although police are investigating, we in the National Parks Department will follow this case to the end.”
.
Kanchana, the director of the Wildlife Conservation Office of the Department of National Parks, Wildlife and Plant Conservation has denied giving permission for Premchai and his friends to hunt.
.
However, she said she received an unidentified phone call on Sunday asking for instructions to apply for a camping permit in Thungyai Naresuan Wildlife Sanctuary. She told him to contact the regional wildlife office.
.
“He’s not my guest,” Kanchana said. “Camping permission must be granted by the regional office.”
.
“While police have moved slowly on this case, showing the lack of transparency in the area, I’d like to congratulate Thungyai Naresuan Wildlife Sanctuary officials for arresting Premchai, being unafraid of his influence,” Sasin Chalermlarp, president of the environmental organization Seub Nakhasathien Foundation said Tuesday.
.
“It’s common knowledge that some people believe consuming panthers will lead to increased sexual virility,” Sasin said when asked why Premchai would target those particular animals. “As for the pheasant, that’s wild game hunting.”
.
Sasin believes the panther skin is for decoration.
.
“Of course it will become part of his his collection. If we checked his house, we would probably find the rest of his collection. I’d like authorities to investigate his house and his hunting history, since the panther seems to be skillfully shot and skinned,” Sasin said.
.
Sasin said he estimates that Premchai shot the panther while the other three men skinned it.
.
Another animal rights activist asked for people to apply pressure.
.
“Social media and the media must put pressure on this case, especially since money talks, so that the case can eventually go to court,” Edwin Wiek of Wildlife Friends Foundation said.
.
If the case goes to court, it would already be a “triumph,” Wiek said, because many illegal poaching cases don’t make it that far.
.
Referring to a couple sentenced in 2010 to five years for picking mushrooms in Dong Radaeng Forest, Wiek said expects a “similar or higher sentence” for this case.
.
Illegal poaching by the rich and powerful is common in Thailand, Wiek said.
.
“The police, rich people and government officials do it all the time,” Wiek said. “I think it’s because rich people want to show off to their friends that they have barami [social power], that they can afford to hunt because they have so much money.”
.
Premchai is CEO of Thailand’s largest construction company, Italian-Thai Development. The firm Suvarnabhumi Airport, the BTS Skytrain, MRT subway and other major projects. Italian-Thai Development also has building contracts in Vietnam, India and Taiwan and mines in Laos, Thailand and Africa.
.
Premchai was listed 35th richest in Thailand in 2011 by Forbes before falling off the list in later years.

?? Construction of the Da Lat–Thap Cham Railway began in 1908, a decade after it had first been proposed by Paul Doumer, then Governor General of French Indochina, and proceeded in stages. Due to the difficulty of the mountainous terrain west of Sông Pha—where the Ngoan Muc Pass rose into the Central Highlands—construction proceeded slowly, requiring several rack railway sections and tunnels to be built. The railway was 84 km (52 mi) long, and rose almost 1,400 metres (4,600 ft) along a winding route with three rack rail sections and five tunnels. The railway tracks finally reached Da Lat in 1932, 24 years after construction had begun. Another railway station existed at the time, operated by the SGAI, a company that had managed the operation of the railway until that time. The job of designing and constructing a new railway station to replace the old one was given to French architects Moncet and Reveron, who submitted a proposal designed by Reveron in 1932. The new station would follow the Art Deco style popular at the time, but would incorporate some characteristics of a Cao Nguyen communal house of Vietnam's Central Highlands, specifically with its high, steep roofs. Construction of the new station began in 1935, directly supervised by Moncet, and was completed three years later in 1938, becoming one of the first colonial-style buildings to be erected in the area.

Throughout the Vietnam War, the Da Lat–Thap Cham line—as with the entire Vietnamese railway network—was a target of bombardments and sabotage. Relentlessly sabotaged and mined by the Viet Cong, the line gradually fell out of use, with regular operations coming to an end in 1968. Following the Fall of Saigon in April 1975, the railway was dismantled to provide materials for the repair of the main line. In the 1990s, however, a 7 km (4.3 mi) section of the line between Da Lat Railway Station and the nearby village of Trại Mát was restored and returned to active use as a tourist attraction.

A 2002 planning document listed the restoration of the entire Da Lat–Thap Cham railway as a priority for infrastructure development for Da Lat and Lâm Đồng Province, including the upgrading of Da Lat Railway Station to handle passenger and cargo transportation. The proposed renewal received the backing of provincial and local governments, and the national government indicated that private companies would also be allowed to participate in the reconstruction of the railway. The project would also include a connection to the North–South Railway at Thap Cham, allowing trains to circulate between Da Lat and the rest of the country for the first time since the Vietnam War. In December 2009, four rail cars restored to look like the rail cars used on the Da Lat–Thap Cham line in the 1930s were put into use on the Da Lat–Trai Mat tourist railroad, carrying signage reading "Dalat Plateau Rail Road".
