Those are photogrammetry palm trees I expect.

Photogrammetry - Wikipedia.

The technology can give very good results, for example studios where they have a large number of cameras in fixed positions taking stills from many angles. The more images you take, the better quality the image could be, but that’s not always the case.

Then there is laser scanning.
