Yep, and having location data is really useful for organizing said photos.

I think it's really neat Google Photos lets you see all photos taken at a particular location. One of my pet peeves is when friends share photos with me that we took together at a gathering and only the ones I took with my phone show up in that list unless I manually add location data. (Inaccurate timestamps are an even more annoying related issue.)
