Ars Technica: Lidar reveals networks of pre-Columbian cities and towns in Bolivia

Ars Technica: Lidar reveals networks of pre-Columbian cities and towns in Bolivia. “An airborne lidar survey recently revealed the long-hidden ruins of 11 pre-Columbian Indigenous towns in what is now northern Bolivia. The survey also revealed previously unseen details of defensive walls and complex ceremonial buildings at 17 other settlements in the area, built by a culture about which archaeologists still know very little: the Casarabe.”

RTL Today: High-tech race to map Ukraine’s damaged historic buildings

RTL Today: High-tech race to map Ukraine’s damaged historic buildings. “Many of Ukraine’s historic monuments have been destroyed in the three months since Russia invaded, but cultural experts are working to conserve their memory using cutting-edge technology and 3D scans. One of them is volunteer French engineer Emmanuel Durand, a specialist in 3D data acquisition, who is assisting a bevy of architects, engineers, historic building experts and a museum director to record buildings in Kyiv, Lviv, Chernigiv and Kharkiv.”

GIM International: Creating a 3D Model of the Famous Budapest Chain Bridge

GIM International: Creating a 3D Model of the Famous Budapest Chain Bridge. “Two Hungarian companies designed a three-step data collection workflow to overcome the challenges in this urban surveying project, which included the use of UAVs and remote-controlled boats for Lidar and photogrammetry data. The result: a digital 3D BIM-compatible model of Budapest’s iconic bridge over the River Danube to assist in preparations for restoration and renovation work.”

‘Architecture as an artifact’: Auburn professors scan 3D digital reconstructions of historic Rosenwald Schools (Associated Press)

Associated Press: ‘Architecture as an artifact’: Auburn professors scan 3D digital reconstructions of historic Rosenwald Schools. “Even with the trusses exposed, and roofs caving in, the Rosenwald Schools from the segregation era still have a lesson to teach. As the ashy paint that clings to the outside of the buildings across Alabama peel more and more with every passing year, two Auburn University professors saw the value in preserving what is left of the 40 remaining Rosenwald schoolhouses before it’s too late. Gorham Bird and Junshan Liu are using drones, 360-degree photography, photogrammetry and laser scanners to create 3D digital reconstructions to keep these buildings “standing” in an online archive.”

Mashable: Digital map of Rio’s biggest favela is reintegrating vital public services

Mashable: Digital map of Rio’s biggest favela is reintegrating vital public services. “From infrastructure to healthcare, Rio de Janeiro’s favelas have remained largely excluded from vital public services. Starting in Rocinha, Rio’s biggest favela, a new digital map hopes to change that. Ran by MIT Senseable City Lab, ‘Favelas 4D’ uses 3D laser scanning technology to digital map the maze-like area.”

Corridor Crew Scans an Entire Ghost Town With a Phone and YOU MUST NOT MISS IT

One of the YouTube channels I subscribe to is called Corridor Crew. The channel’s description is “We run a production studio based upon ingenuity, hard work, and friendship. Watch our ups and downs as professional creators!” Its most recent video was about using LiDAR to scan an entire ghost town. WITH A PHONE. Cerro Gordo is now available to view (and in some cases walk through!) at https://poly.cam/cerro-gordo . I watched most of the backstory video with my jaw on the floor. The progress made by LiDAR scanning apps is unbelievable. If you didn’t realize how far phone-based 3D scanning has come, do yourself a favor and watch the video or visit the ghost town online.

GPS World: Earth Archive project aims to create digital twin of entire planet

GPS World: Earth Archive project aims to create digital twin of entire planet. “The Earth Archive Initiative is an unprecedented scientific effort to create a digital twin of the entire surface of the Earth – and everything on it. By scanning the planet’s land surface with very high-resolution lidar, the Earth Archive will create a true three-dimensional digital twin of our world — an open source, digital record of the Earth that will reflect the landscape exactly as it was at the time of scanning.”

Google News Pilipinas: University of the Philippines opens portal on Taal Volcano data, 1st in Asia to offer public access

Good News Pilipinas: University of the Philippines opens portal on Taal Volcano data, 1st in Asia to offer public access. “The Taal Volcano LiDAR datasets were derived through the use of airborne systems mounted on an airplane. The output of the LiDAR sensor is a 3D point cloud containing points that were scanned. The LiDAR technology was able to generate maps with resolution of up to 1×1 meter which can be used for planning and reconstruction of areas damaged by the Taal Volcano eruption in Batangas on January 12, 2020. The Taal Volcano mapping is free and downloadable by anyone with internet access and by most modern GIS software.”

Ars Technica: Archaeologists map centuries of history beneath world’s oldest cathedral

Ars Technica: Archaeologists map centuries of history beneath world’s oldest cathedral. “The Archbasilica of St. John Lateran doesn’t quite look its age. The basilica, where the Pope presides in his role as Archbishop of Rome, was already ancient when it was rebuilt in the 1650s…. Centuries of Roman history lie buried in the darkness in layers stretching down to 8.5 meters (27.89 feet) below the modern floor of the cathedral, and the subterranean archaeological sites are like a honeycomb through the city’s Caelian Hill. Now, using a combination of laser scanning and ground-penetrating radar, archeologists have made a complete map of the site.”
