There's adjacent work for any utility, but the type I was doing was cable/fiber.
The crux of the concept is receiving a map, sometimes partially completed, sometimes with partially incorrect information, and using easily placed symbols to make corrections for submission.
Whatever % of that you feel comfortable doing in the field, you do, with the remainder being finished wherever (often in front of a TV show, from what I saw).
A slightly more complicated (and nonpublic) version of contributing to OpenStreetMaps.
