:download: Dados LiDAR (Light Detection And Ranging) do território de Portugal continental podem ser descarregados a partir do Centro de Dados da Direção-Geral do Território (DGT).

"Neste momento estão disponíveis para descarregamento os dados referentes a 90% da área do território, sendo que os dados para a zona noroeste de Portugal continental estão ainda em fase de produção."

A while ago I started making oblique mountain views based on #lidar datasets. Sometimes lidar doesn't cover an entire view, so larger-scale data need to be used as well, with the products merged for the final result.

Here's a story in 4 pictures about making one combined-dataset view - using a range of tools: command line data processing, @qgis , @inkscape and @Krita . See alt text for details. 🏔️ 🗺️ ❤️

McLeester and her team used drone lidar technology, which involves flying a drone low to the ground and using pulses of light to map the topography of an area in great detail. Historically, lidar imaging has used planes, which can’t get as close to the ground and therefore aren’t able to pick up as much detail.

“This is some of the earliest data with drone lidar,” McLeester said. “I think with this new technology, we’re going to find more and more of these agricultural sites across North America in unlikely places.”

WPR · Archaeologists make surprising discovery along the Menominee River on Wisconsin borderA new discovery along the Menominee River calls into question what archaeologists thought they knew about the scale of Indigenous agriculture before the arrival of European settlers.

I will never fully understand #ElonMusk’s aversion to #LiDAR for #Tesla vehicles.

No system is perfect, but adding it could provide their #AI with some extra, crucial data—especially when traveling in the rain. 🌧️

"What if I told you that one of the most well-capitalized AI companies on the planet is asking volunteers to help them uncover “lost cities” in the #Amazonia—by feeding #machinelearning models with open satellite data, #lidar, “colonial” text and map records, and #indigenous oral histories? This is the premise of the #OpenAItoZChallenge, a #Kaggle-hosted hackathon framed as a platform to "push the limits" of #AI through global knowledge cooperation.

In practice, this is a product development experiment cloaked as public participation. The contributions of users, the mapping of biocultural data, and the modeling of ancestral landscapes all feed into the refinement of OpenAI’s proprietary systems. The task itself may appear novel. The logic is not. This is the familiar playbook of Big Tech firms—capture public knowledge, reframe it as open input, and channel it into infrastructure that serves commercial, rather than communal goals."

»#Xiaomi-Gründer Lei Jun griff #Tesla während der Präsentation am Donnerstag frontal an […] Das Topmodell des YU7 soll demnach 329.900 Yuan (rund 40.000 Euro) kosten, hat eine Reichweite von 760 Kilometern mit einer einzigen Ladung und beschleunigt in 3,23 Sekunden auf 100 Kilometer pro Stunde. Es ist in neun Farben erhältlich und mit einem #Lidar-Radar ausgestattet. Dank einer 800-Volt-Plattform soll das Auto schneller laden als ein Tesla Model Y.«

Over 100 Chachapoya structures discovered at Gran Pajatén in Peru’s Andes

Archaeologists have uncovered over 100 previously unknown structures at Gran Pajatén, a centuries-old archaeological complex in Peru’s Río Abiseo National Park. The discovery fundamentally reinterprets the site, one of the most iconic remnants of the Chachapoya civilization...
