> really good data sources with fully open access (no user accounts necessary)

Ola!

I am the author of the repo, worked in satellite projects for the Galician goverment some years ago.

You don't need an account to download the data from OSM (you do need to contribute back, which makes sense IMO). You don't need an account to download tiles from some publicly available sources (i.e. https://pnoa.ign.es/ in Spain) but I prefer to made the code work with MapBox and let them pay the infra (until they stop free offering). Happy to share a simple snippet to use a different tile provider.

Any public dataset (that I am aware) is not really meant to be frequently updated, at best you get a second version release a year later. A lot of public money (I know because have been payed a small portion of these budgets) is spent on building datasets that are used for a couple of research papers, uploaded to the web and then become outdated.

If I want to help updating them or correcting label mistakes, in most (all?) cases, there is no practical way for me to do it.

I believe that OpenStreetMap has the potential to be the best publicly available spatial "dataset" for (some specific) CV use cases.

If we focus on creating ways to contribute with quality data (the idea behind this small project), it will just keep getting a better dataset, that anyone can contribute to be up-to-date.

Thanks so much for the add'l context, that all sounds very real. I have worked in/around academic projects, and maintaining otherwise useful assets and data that follow on from individual projects sounds like a somewhat ubiquitous challenge. I am a systems admin and IT consultant by day, my interests in ML and cartographic endeavors are extra-curricular, but I appreciate what you're doing!
