Supposed to be [1][2] according to [0] but only by lots of clicking through GUI? It's really intuitive. GSI(Geospatial Information Authority of Japan) download site is a lot better, though they're more geography focused.
Free reminder that the USGS is involved in an epic, nearly decade-long collection of mid- and high- density lidar of the entire continental USA, and the QC'd data (point cloud & derived) is published gratis for everyone to use:
I must say this is tremendous. There are many different AIGC explorations in 3D topics, with such high quality dataset, it will greatly assist current workflow and accelerate the 3D creative evolution.
> Switzerland is one of the first countries to possess a detailed 3D buildings model covering the whole country. This digital model of Switzerland consists of approx. 70 million 3D objects. Besides every single building in Switzerland and the Principality of Liechtenstein, bridges, cable cars, forests, individual trees and geographical names are also represented in 3D. Two movement modes enable interactive navigation through space. Discover digital Switzerland from the air in flight mode or take a virtual stroll around a 3D model of your own village or neighbourhood.
I wonder if this dataset has been added to OpenStreetMap (or what the legal restrictions could be). If I look at Zurich on https://osmbuildings.org/ it seems like it has all the buildings in 3d.
This might be a stupid question, but isn't Switzerland known for its countless hidden bunkers and defense positions? Doesn't mapping and publicly exposing basically the whole country only bring negatives and nothing positive?
I though Switzerland's defense was more based around being mountainous and having explosives planted in critical tunnels/bridges and having a large percentage of the population armed and trained for national self defense. Basically in a ground invasion would be deadly and slow with no mobility and resistance everywhere.
Besides that it's hard to imagine which foreign power would have incentive and power projection to even try it.
The way I've understood it is that none of their defense is hidden, it uses the natural and societal benefits. Most of that could be gleaned by anyone with access to satellite images and wikipedia.
That might all be outdated info though, it'd be interesting to see where I'm wrong though!
I have one of such fortifications, called Toblerone line, running around our place in canton Vaud. The whole line is maybe 15km long from Geneva lake up the Jura mountains, made up from concrete spikes (even raisable in the middle of roads), blowable bridges and around 15 tiny concrete fortresses (fortinettes), all in plain sight, mostly visible on google maps/street view.
All built around 1930s. There is popular hiking trail along all this, since nature and forests around it are pretty and well maintained. No secret really. Same for many other old stuff. New stuff should be hidden on bases/remote places.
Btw checked our building and surrounding ones and its pretty precise but not up to date with 2024 finished construction.
In france, the national geodata institute (IGN) has captured lidar data of the whole country (20 points per km2 if memory serves, in the OP it’s 30p per km2).
