Open Data Portals
Government and institutional portals that catalog and publish open datasets for public and research use.
Open data portals are official platforms — usually run by governments or international institutions — that catalog and publish datasets for public use, typically covering statistics, geography, transportation and public services.
They're distinct from community platforms like Kaggle in that the data is generally authoritative and sourced directly from the publishing institution.
