Fairly accurate and current 3D mapping has been available for many areas free from usgs.gov for several years as a result of LIDAR. It is used by cellular/radio companies for shadow/fresnel predictions for RF. In 2018, I bought a modeling package for a city to determine what views permitting taller buildings would affect, and potential views from elevations on a proposed structure. You can download LIDAR data and a some tools for free: https://www.usgs.gov/faqs/what-lidar-data-and-where-can-i-download-it?qt-new... But the article references LIVE 3D data. I'm sure that would be "crowdsourced" from live device data. With enough bandwidth - 5G+ - image points, position and attitude data can update the world, a few billion points of data at a time...

3D mapping is here and improving. Some of the drone jobs I've been doing as a remote pilot in command are mapping using DJI Terra using their RTK system and LiDAR:
Mostly for inspections but also inventory of assets.
Skydio now has 3D imaging using their drones, as well:

Skydio is a company that was founded by ex Tesla engineers, and their hallmark is having amazing autonomous capabilities.

The predictions found in the enclosed link, if true, mirror Dave's
response to Hal's frightened question: What is going to happen? — Something wonderful.
Many companies are working on versions of what is discussed; even if
half of those companies efforts come to fruition, the future will effect a transitional jump.
If that occurs, whither goes Amateur Radio? At a minimum, every
radio manufacturer will be behind the curve.
