Route counts combine dedicated sources with broader regional and global discovery routes. They do not claim that every dataset contains observations for every country; Atlas verifies country coverage and source metadata during research.

Official Netherlands discovery anchors

These are country-specific authorities and catalogs, shown separately from executable connectors. A reachable official portal is a discovery route; Atlas still verifies the dataset, administrative level, licence and freshness before using it.
