I've seen a few of these tutorials and have done some cursory searches but haven't found any services that automate generating Minecraft maps from any open map standards. Is there anything out there for this? EDIT: Hmm, actually clicked the link in TFA and found this https://www.youtube.com/watch?v=Wha2m4_CPoo https://www.youtube.com/watch?v=Wha2m4_CPoo which is closer to what I'm imagining, but is still a process and not a service.
