Gain seamless access to origin-destination (OD) data from the
Spanish Ministry of Transport, hosted at
<https://www.transportes.gob.es/ministerio/proyectos-singulares/estudios-de-movilidad-con-big-data/opendata-movilidad>.
This package simplifies the management of these large datasets by
providing tools to download zone boundaries, handle associated
origin-destination data, and process it efficiently with the 'duckdb'
database interface. Local caching minimizes repeated downloads,
streamlining workflows for researchers and analysts. Extensive
documentation is available at
<https://ropenspain.github.io/spanishoddata/index.html>, offering
guides on creating static and dynamic mobility flow visualizations and
transforming large datasets into analysis-ready formats.
