3dgeonames - A 3d open location code written in perl5 — Ervin Ruci, 20 minutes; accepted

Location encoding has gained a lot of attention lately, from newer iterations of the popular geohash algorithm, to serious commercial efforts like what3words, to new and revisited open source systems like Google's plus codes. Still, nobody has tackled the problem of 3d location encoding, yet, although there is an obvious use case for it with the growing popularity of 3d mapping. 3dgeonames is the 3d version of the perl5 module Geo::Code. It produces location codes for latitude,longitude,elevation triplets with a resolution of 1 meter for an elevation of up/down to +- 17576 metres. This talk expands of the use case and methodology used to solve this problem.
