On nautical chart plotters/GPS the Go Home feature is called the MOB button, or man overboard. There was an article in Ocean Navigator about 10 years ago about a group of guys sport fishing off Cape Hatteras. Faced with several hour return back to the marina they all went below to sleep off a day of sun and drinking leaving one guy on deck to man the boat. Nature called and you guessed it... a couple of hours later someone woke up and realized he was overboard. Pressing the MOB button caused the autopilot to turn the boat, waking the everyone else on board as it heeled. They called the coast guard, but ultimately returned to the guy floating in the ocean. Very lucky indeed.
There is a book by Nigel Calder titled "How to Read a Nautical Chart" that goes into GPS and the technology of cartography in detail. Although its not specifically for terrestrial GPS most of the theory is relevant and some of the detail about map types (raster, etc.) very valuable. It's a whopping $12 for the Kindle/E-readers at Amazon and probably free to anyone in a big city with a library card. It may help explain why Basecamp does a few of the things it does.
