On Tuesday, when the first photo of the charred wreckage inside the Notre Cathedral appeared online, engineers around the world said an observation was clear: restoring old buildings to the glorious past builders may turn to cutting
Edge technologies related to the future.
Design experts say that even before engineers can get into the deepest part of the structure that is still smoldering, conservatives and engineers are already thinking about it, to restore one of Europe's most iconic buildings to the legendary past, what modern technology might be brought about.
They acknowledge that this is a speculative activity, but it is closely related to the future of UNESCO's World Heritage site.
Reconstruction work may take advantage of expertise gained from disasters such as the Fukushima Daiichi nuclear power plant in Japan and the National Museum of Brazil fire, experimental robots and new digital tools are used to go to places where people can't safely risk and replicate detailed artifacts lost in the fire.
Experts say that throughout the reconstruction process, engineers and protectors will be forced to work with a constant
The question now is: "How do they integrate the brand new 21st century technology with the ancient craft and construction industries to keep the cathedral preserved and alive?
Catherine Malone said
France, interim chief depositary officer of the National Historical Protection Trust, a privately funded non-profit organization based in Washington.
"It will be a very interesting intersection of technology and craftsmanship, and the world will keep a close eye on how they are achieving this.
"Some of the technologies that will be used to restore Notre have been on display.
On Monday, an orange wall of fire roared past the roof of the cathedral, and hundreds of firefighters fought back,

According to French newspaper Le Parisien, help firefighters put hoses to control the fire before the fire destroyed two iconic belfries of the cathedral.
"Thanks to these drones, thanks to this new technology that is absolutely inevitable today, we can make tactical choices to stop this fire when it may occupy two belfries, A spokesman for firefighters in Paris, Gabriel Plus, said.
On the ground, the robot fire extinguisher giant exploded the middle hall with water, reducing the temperature of the glass
The room was packed with people, according to the newspaper.
Experts say some of the same technologies may be used in return for the next critical months-
Century cathedral attracted 12 million visitors last year.
Experts say one way to get started is to introduce other drones to investigate the locations inside the huge cathedral that are too dangerous or damaged for engineers.
Jerry Hajjar, professor of civil engineering at Northeastern University, said drones can be equipped with sensors.
Small cameras and laser scanners.
This will allow the engineer to record the fire damage and create a highly accurate three
Stereo vision of a specific location within the church.
Hajjar says other sensors can be like X-
Ray and estimate the mineral properties and stress levels of the structure.
Hajjar said, but the documentation work may be harder than it sounds, noting that the drone has to rise with the connection of the device and the lower the battery life, the longer it can stay in the air.
It could be particularly challenging in a building up to 226 feet, he said.
Another way to test the integrity of the cathedral could involve robots, Hajjar said, noting that research on using climbing robots to check and repair steel bridges is already in progress.
"After the Fukushima disaster, the value of using robots becomes very obvious," Hajjar said . ".
"They don't want to send people in because they're too dangerous, but realize that they can use crawling robots to get access to the site and get valuable images.
"This could be 3-
Surveying and Mapping engineers will be required to consult existing problems.
In 2015, Andrew Talon, associate professor at Vasa College, who died of brain cancer last year, told National Geographic that he had completed a full laser scan of the entire Cathedral.
Experts say Talon's digital technology can provide important information for any reconstruction effort.
There is only one problem: according to the Atlantic, it is not entirely clear where Taron's scans are, which can be stored on a single hard drive.
A popular video game can also provide another source of digital information about Notre.
In 2014 articles on edge, Caroline misser-

She said it took her two years to create a model of a church that captures the interior and exterior of the building.
Experts say that once engineers have a clearer understanding of the structural integrity of the church, they can design the right roof.
They will have to decide whether to rebuild the roof frame with wood.
If they do not choose structural engineered wood that can reduce the weight of the roof and provide artistic freedom, engineers can choose to use steel.
Gary house said that while it would leave the original wooden roof of the church, Steel would allow engineers to use less material, even lighter than Wood, chief operating officer of durable group, this is a collection of companies specializing in historical restoration.
Replacing what is lost may not be the biggest challenge, Howes said.
Instead, he said, it will combine old and new to provide a window for admirers around the world to include upgrades and conform to modern building codes.
"The project is more emotional than structural," he said . ".
"Everyone wants the cathedral to look like they remember.
Fortunately, France has an advantage over the rest of the world, Mr Howles added.
"Some of the best craftsmen in the world are in France," he said . "
"Whether it's a restoration or a contemporary work, they don't lose a historic deal like we did in the United States. S.
We go there every year to learn from them. ”James W.
Shepherd, director of conservation and facilities at Washington's National Cathedral, whose damage from the 2011-magnitude earthquake has yet to be repaired, said the days after events like Monday's fire would be a critical moment for the Virgin.
"They need the expertise there to make sure they are cleaning up the ruins and taking out what is saleable or not saleable," said Sheppard . ".
"What you're talking about is that what they're trying to pull out may be something 700 or 800 years old that could be partially burned or partially damaged by water.
In Brazil, 90% of the national museum collections were burned down last year. D data to re-
Make precious items lost in the fire.
Experts say the same technology can be used in Paris if they can get similar data.
