It sounds like it would more be used for relative elevation differences. Is GNSS the gold-standard for that? I'd have thought you could do better with a laser and a level.
- AnimalMuppet 6y agoI'm not sure that we have levels that are accurate enough for that.
- tgb 6y agoReally? I can't tell what accuracy a good theodolite gets, but this consumer device [1] claims 3/16ths of an inch at 30ft. Obviously that won't scale to 1km distance like they're doing in this, a professional one seems competitive with the quoted ~2cm accuracy.

- WJW 6y agoAbsolute gold standard for use in a laboratory, probably not. But GNSS is definitely the instrument of choice for 99% of surveying and navigational purposes.
