A decade ago I presented this pair of slides to an all-staff seminar at the Australian Antarctic Division. First shows a lidar pass as a reasonable scale for piloted aircraft. Second is a dense point cloud of a ship in sea ice showing a reasonable scale for RPAS/drone operations.

This is still true. At the time no small RPA existed that could operate in those conditions. In 2021/22 I was flying one in the Arctic, and it turns out slide 2 was very optimistic!

“If you’ve never heard of LiDAR before, it stands for “Light Detection and Ranging.” It can map out an area by firing lasers at it and recording how long it takes for the reflected light to return. It’s a handy way of creating a 3D model of a physic ...continues

AI aids large-scale mapping of Angkorian reservoirs beyond Greater Angkor

A group of international researchers has harnessed the strength of artificial intelligence to reveal previously unknown reservoirs from the Angkorian period in Cambodia...

Sony Electronics Announces the World's Smallest and Lightest[1] Miniature Precision LiDAR Depth Sensor

https://www.prnewswire.com/news-releases/sony-electronics-announces-the-worlds-smallest-and-lightest1-miniature-precision-lidar-depth-sensor-302426709.html

Fairly disappointed, but not altogether surprised, that the new Non-forest Tree mapping from Forest Research is not really useful for mapping trees on #OpenStreetMap. Mostly it only has 1 m resolution Lidar, so the map shows canopy above 3 metres in height. Undoubtedly useful for other purposes, such as shade calculations.

Schade #heise. Wieder mal ein Downer für mich: Ein für mich prinzipiell sehr interessanter Artikel zu Rasenrobotern, der mit keinem Wort erwähnt, ob man eines der Geräte auch ohne Verbindung zum Hersteller voll nutzen kann.

Starke Abhängigkeit zu einer App lässt mich vermuten, dass damit auch die #Cloud mitgemeint ist.

Dann hoffe ich, dass mein alter #Gardena möglichst lange noch durchhält. Der braucht weder Internet noch Cloud noch App für seine Funktion.

Nebenbei: der flexible Begrenzungsdraht scheint mir immer noch deutlich praktischer zu sein als die teuren High-Tech-Alternativen: einfach zu installieren, einfach zu korrigieren/finetunen, lästig aber akzeptabel bei der Fehlersuche bei Kabelbruch.

YMMV.

Urban settlements in the #Amazon region? They existed long before Columbus. But knowledge about them was more or less lost for a long time. In her keynote lecture on Tuesday, Bolivian archaeologist Carla Jaimes Betancourt from the #UniBonn explained why #Lidar technology is now bringing back this knowledge and what new discoveries have already been made.
In an interview, she also told us why she became an archaeologist
