The more amateur world I am familiar with (OSM et al) does not go for a theodolite at all. The general approach is to satellite-trace the place out and use GPS tracks for what it can’t cover.[1] For more detailed shapes or up-to-date imagery, OpenDroneMap might be used to assemble own drone imagery.

The rendering part is usually done by leaflet on the web. GIS software should allow importing from OSM too.
