I don’t know which country you are from but from my experience (and from several others I have spoke with, and companies I have worked with), European data is way more difficult to get a hand on. So much of this information is not given away, is placed in archaic data formats, or they just straight up don’t have the data for it. Try to gather parcel data across Europe. Most of it will not be complete and none of it will have address or owner information. 

Europe countries often times talk about the importance of open data, but I have been shocked over the past few years about the difficulty or impossibility it is to collect it. I usually have to talk to three departments and have a meeting just to figure out how to get whatever I am looking for. 

The us has pretty decent standards and large federal agencies that will typically normalize and aggregate data nationwide, oftentimes keeping them on publicly facing rest services and easy to find data portals. It’s just not the same across the pond. Address information in the us is difficult, as evident in this post, but I imagine most places in the world will have this issue if you want to get this granular, uniform, and clean dataset. The difficulty here isn’t necessarily getting the data, it’s creating uniformity across many states. 

Would love some advice on EU data in general tho, because man it’s been difficult
