he has insisted that any pace deal with russia depends on moscow's forces. pulling back today at pre invasion positions. he also a cold for diplomatic options to say those still inside the as of style steel plant and mario pulp. and you're up to date on t w op. next is our take show shift, we'll have more headlines at the top of the hour. i'm jarrett rayden berlin, have a great day with it. started out with spooking intimidation, and transformed into an orgy of hate and violence. the history of the ku klux klan, the oldest terrorist organization in the united states,

its members fight for racist state, ruled by white supremacy. what we're talking about here is not only disorganized violence, it's not only terrorism. it's politics. found it over 150 years ago. it's repeatedly died out, but always been resurrected. the ku klux glen starts may 11th on d w. ah. when will the leaning tower of pisa collette many world famous monuments are at risk you to climate change war and negligence. but with the help of 3 d scans, drones and a i, we can save these iconic buildings. at least virtually i would a walks. that's all topic on shipped today. ah, shoot. having digital backups comes in hand like of your diploma or your

favorite. todos the same is true for historic buildings that have deteriorated over the years. like mexico cities famous metropolitan cathedral, which has been damaged by several earthquakes. luckily is 3 d model is earthquake proof. that's also a detailed 3 d model of the gateway of india and moon by which has been eroded by sea water. but it's estimated that so far, only about 15 percent of the world's casual heritage has been digitally preserved by now. ukraine's cause will have it. it is especially at risk. it's not only buildings and god says that in danger. but all kinds of online archives of things like paintings and literature, to me in ukraine, russian bombs are not only killing people and estimating homes and infrastructure. they're destroying cultural heritage too. right now everything's at risk. everything from physical museum collections to records of library holdings,

to servers with web sites. at the end of the day, the internet is as physical as, as anything else that depends on servers that have to be connected to power and connected to cables. and those servers are at risk of being destroyed, it's servers or destroyed digital backups of art and other records are lost to that's why quin number ski and a group of librarians researchers and programmers join forces to start saving, ukrainian cultural heritage online. soon after the russian attack feature, volunteers began archiving as much as possible relying and what they could find from ukrainian cultural institutions online were trying to, to capture those websites with everything that's on them. any pdf, any image, any 3 d model, or, or walk through, or trying to capture a version of, of all of it so that, that can be, you know,

thing that is safe and outside the country. ah, some tech companies are supporting search by providing servers in storage for free so far, the group has saved more than 30 terabytes of content from over 3500 websites. more than 1300 volunteers helped with the task. sometimes it's not even like a firefighter squad, it's, it's more like, you know, neighbors with water buckets. you know it, many of us had not really done any work on web archiving before this year on quin dombrowski hope so chose archive will never actually be needed. we, we don't actually want these to be useful if they're useful it's, it's a sign that something terrible. it's happened in terms of the preservation of, of cultural heritage. the great thing about this project, anyone can pitch him. you can learn more at social dot org. sometimes doing your part to digitally preserved cultural heritage is simple. other times more expertise is needed. ah,

the great wall of china is the world's longest manmade structure. it's more than 20000 kilometers long over 2000 years old and in desperate need of repair. drones are used to survey parts of the wall that are difficult to access. after filming the wall of close, the data is then used to create 3 d models. a i is then used to scan these models, identify the damage and plan the necessary repairs. the non profit cy arc specializes in 3 d laser scans of endangered cultural sites. here's how it works. laser scanner sensors pulses of light by measuring how long it takes for the lights to be reflected off various surfaces. it's possible to determine the size and surface material of objects. this method is called lighter. another technique that's used is photo crematory, where overlapping photos

a combined to create extremely realistic and 3 d models. anyone can check out the scans on google's arts and culture platform or download the datasets on open heritage. 3 d digital technology has become critical in reconstructing destroyed buildings. in august 2015, the temple of bounce, yameen, and palmera syria was reduced to rubble by the islamic state. terrorist group. however, back in the 1950s, swiss archeologist to pull colors, excavated, undocumented the temple. the information you collected back then made it's possible to create a virtual reality image and 3 d model, or the temple of bounce yameen is supposed to be rebuilt, just like palmer's arch of triumph, which was also destroyed by ins. using digital models, robots built

a smaller replica of the archway which has been exhibited in several cities. hopefully, the arch of triumph can one day return to its original location in syria. in 2019 of fire destroyed large parts of the natural dom cathedral, the incident shall trans and people worldwide businessmen. one of the most iconic landmarks in paris was lost forever. fortunately not, it's cowardly being restored. true to be original. thanks. in part with this man, andrew tell him no tra, dom was a lifelong passion for andrew talon. here the belgian born art historian is walking around the 850 year old cathedral before the fire. he was recording a $360.00 degree video, which is why the image looks a bit distorted. another interesting detail to see about this is a bit of that was often used as

a joint between edged bedded elements such as this talon use. laser scanning technology to map no to dumb. he collected more than 1000000000 data points, which he then linked to photos of the scanned areas and became fascinated with the cathedral from a very young age. his work there in trying to create a global laser survey that is really what makes his work stand out there. so we are still reading the benefits of that effort from 2010 in 2012. he scans not just not sure i'm you know, late does since it's not hundreds of cathedral from sweden to spain not turned on was, i think, a crown jewel and a lot of ways. and andrew talent did not live to see exactly how important his scans would turn out to be several months before the fire destroyed. no tread arms roof inspire. he died of cancer. part of the reconstruction plan is based on

talents where it is one of several records that we have of the pre fire state of neutral. and this is of course, critically important as the decision was made to restore the building ident and queen neutral damage. restoration team combined talents, models with additional scans, resulting in this impressive 3 d model. us software developer autodesk provides a cloud based data platform, which gives all the stakeholders involved in reconstruction access to the latest records. that makes it easier to plan construction work like calculating how many oak trees need to be felt to replace no transpire. france is determined to restore the cathedral true to its original design. the one that andrew talon and his team mapped before the fire thus safeguarding its

future. there are many ways in which cultural heritage can be endangered. one prominent example art stolen by colonizers, the kenya based non profit, african digital heritage, is working to digitize these treasures. and we frame how this history is documented . yet another advantage of digital copies, cultural heritage can be showcased to a global audience online, ah, artifacts from african history. ideally, you might see them in person in the museum collection, but kenyan historian chow tianna minor. once more world wide accessibility, we decide for many reasons, one of the primary ones being access, enabling audiences practitioners be such as to access material remotely to access material from different countries. you know,

you don't have to be in kenya to access cultural heritage. another reason why we digitize is to preserve the material the digital heritage specialist trains museum staff across kenya. the teams have a huge task ahead of them, digitizing tens of thousands of books, papers, and photos. some of them hundreds of years old. i lot of the time when i'm training on digitization, i would say read the process of digitization is not about just sticking the photograph. it's about the decisions that you make before you take this photograph . the 1st step is inspection and selection. not everything can be digitized choosing the right objects is also a way of writing history. when we are digitizing, do we still defeat the theme? colonial kind of tom. do we still repeat the ways in which our people are objects i

describe, or is this an opportunity to say okay, let's change how things are described. 0, one example. the mama comes in the 1950s. the british army and colonists detained many canyons and forced labor comes using a cable material. the african digital heritage non profit has created 3 these guns of the country. we've been going out into the field documenting these sites in that kind of i would say akila, gina, sans to see what struck to and still exist as well as contextualizing this tangible heritage, dis, tangible, nato buildings in land to people as memories and people stories digitizing african cultural heritage is a way to re examine, contextualize, and preserve this history and culture. ah,

i feel that they walk about read going to digitize his see is also about connecting time. we are connecting the past the present. and in this very act we are shipping future. 7 thanks to digitization, it's possible to save, got casual heritage for generations to come. but 3 d models shouldn't be regarded as mere replacements or backups of the originals. instead, there a chance for people across the globe to get to know cultural sides they otherwise may have never seen was your take? can monuments really be capital on the screen? or do you need to physically be there to get the full experience? let us know what do you think as often now, bye bye. ah ah

ah, ah, africa with 4 dw travel reporters. and our check in special will explore them piled b of kenya to the most amazing motorcycle route in south africa. and explore traces of colonialism in nigeria. check in with next on d. w. guardians of truth on exiled turkish journalistic john dunder, i had paid almost every price of being a journalist in a country like through key and mexican investigative journalist on i believe this. they want to kinda nice to know what is happening there
