How to easily join 2 pieces of geolocation terrain?

I think it can be done by a lot of manual moving, but I also imagine someone has a nifty trick up their sleeve to get the job done quickly?

“Quickly” depends upon how fast you are at tweaking geometry.
There is no magic trick that can instantly make the two TINs into one functional terrain.
The up side is you’re about to become a Move/Inference Lock Black Belt.

See this topic for ideas…

How does zoom effect terrain data import?

Making two or more TINs into one functional terrain (no gaps, overlaps or stray edges) is not a quick task. See Ref: [1] regarding functional terrain Subsequent operations may be difficult or impossible unless the terrain is functional. The problem being the geometry of successive grabs does not perfectly align with each other. See image Ref: [2] … Shadows are on. Note the gaps where the two TINs overlap. You might try using this plugin to make multiple TINs into a functional terrain. YMM…
