Data Hub
Oh, hey. Fancy seeing you here. Realized that button didn't line up with an existing category, huh? Probably wasn't too hard to figure out.
I have... let's say, opinions on the the level of data available if you go looking, but I must admit it's terribly useful to have at my fingertips. I wanted a place to put some of my resources and there didn't really seem to be a good place for them on the Atlas. So, this is a sort of official-unofficial page, like a storage closet of sorts. I let it link to the outside because all this information is available elsewhere on the internet anyway - you'll find it if you go looking. It's just nice to have in one place.
Some of these links are a bit circular, since they aggregate links to other datasets.
A small collection of public transit APIs.
An appropriately-named, massive list of datasets for public use. Keeps track of which ones are still working, too. Entirely links to other sites.
Datasets provided by Florida International University.
27k+ datasets from NASA and counting.
Public data from Tableau.
Large datasets from the Society for Science. Mainly links to other sites.
US voter and election-related data. Links to PA.
Datasets straight from the US government.
