The session focused on using the Scholarly Migration Database (by

#flowmapblue by Ilya Boyandin
https://flowmapblue.github.io/flowmapblue.R/ and
#flowmapper by Johannes Mast

Scholarly Migration Database
💻 One of the tutorials at @IC2S2 2025 in Norrköping is our tutorial on analyzing and visualizing large open human mobility data in Spain using R #rstats: https://www.ic2s2-2025.org/tutorials/
It will cover #spanishoddata (ropenspain.github.io/spanishoddata/, by @EgorKotov , @robinlovelace , Eugeni Vidal Tortosa),
#flowmapper (https://github.com/JohMast/flowmapper by Johannes Mast), #flowmapblue (https://flowmapblue.github.io/flowmapblue.R/ by @ilyabo), with under the hood data crunching using @duckdb #DuckDB .
#30DayMapChallenge #aNewTool #rstats #spanishoddata ( https://ropenspain.github.io/spanishoddata/ ) meets #mapgl and #flowmapper to show differences between daily home-work-home trips and all other frequent and infrequent trips in Barcelona.
Not only trying a new tool (#mapgl #rstats, thanks to https://github.com/walkerke), but also contributing to a new tool (#rstats #flowmapper, thanks to https://github.com/JohMast).
Get Spanish Origin-Destination Data
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.

L’Afrique, un continent isolé dans la mondialisation (situation en 2018)
Indépendamment du choix crucial du système de projection à l’échelle mondiale, les cartographies de migrations mondiales réalisées à l’échelle internationale (au niveau des pays) donnent à voir ces flux démographiques par le seul prisme des États qui peut être vu comme un carcan. Ces flux, parce qu’ils vont s’exprimer entre de nombreuses zones vont être d’autant plus nombreux, et, présenter des amplitudes importantes qui vont conduire à sélectionner l’information à représenter. L’enjeu est ici d’éclaircir leur image (réduire l’effet spaghetti) [1], ce qui suppose généralement de ne représenter que les plus importants, ceux qui sont jugés significatifs. Ces derniers vont...
