what is the source for this commit??

because by a cursory glance at the various features added I have a feeling that at least part of this commit is additions that do not exist in reality. for example this commit adds English named hot5els/guest houses in the middle of Africa, while its possible that such a thing exists I doubt that it is real. this also adds a dog park that when you look at the default imagery layer for the area (somewhere in Nebraska) seems to be in the middle of a marsh or swamp of some sort, so unless some construction has happened in the area since the imagery updated (I dont know when it last updated) that along with the fact that the feature is called doggy park which doesn't seem like a name for a park (from my experience in the US they usually are named after a person, movement etc. and not just their purpose alone).
