This is getting very close to actual field survey work and IMO the best app, by a mile, to carry out the scanning part in this kind of setting is Dot3D. It's basically been built for larger-scale capture and reliable loop-closure.
Here's a scan of several km (!) of length all done with Dot3D on an iPad [1]. You can also explore the point cloud on the web.
Also, digging a little deeper, here's a study comparing the accuracy and loop-closure capabilities of several 3D scanning apps. It's spot on. [2]

- danielvf 4y agoLink 2 is clearly content marketing. It's a blog with only one post. Though it claims to be a comparison of tools, it only mentions the name of Dot3D, refers to all other tools by number, so you can't look at them, and is written by someone on the Dot3D team.
- FinnKuhn 4y agoAlso two of the three last posts of the account you replied to are just tweets from the Dot3D founder...
- traspler 4y ago300$/y is a bit much for hobbyist street scanning though... The linked content marketing blog post shows Scaniverse to be nearly as good, so that's nice to know as an alternative.
