✨ NEW TOOL FOR #MOBILITY DATA #DATAVIZ ✈️🚚🚗🏃

Do your visualisations of origin-destination matrices look like a mess of criss-crossing hairs? Maybe you could benefit from our #EdgeBundling tool by me, Oula Inkeröinen, @miladmzdh and Olle Järv!

🛠️ The tool: https://doi.org/10.5281/zenodo.14532547

This tool is an output from the #MobiTwin project funded by the #EuropeanUnion through the #HorizonEU programme.

To support using this data, we have also developed an #EdgeBundling tool to aid in visualising complex origin-destination flow data:

We also provide a ready-made edge-bundled network on NUTS 2 level lead by Oula Inkeröinen:

Great! My abstract got accepted into #LBS2025 conference!

I will be presenting my work on #StudentMobility and an #EdgeBundling tool.

This year Location-based Services is in Espoo, so I can just ride the metro there. Travel budget will be around €15. Good times.

Anybody else going to #LBS?

Alright, I will share my map for Day 2 of #30DayMapChallenge again. It depicts regional student #mobility across Europe a few years ago. As the data contains 200 000+ flows, straight line geometries make a fuzzy mess, but through aggregation and a technique called #EdgeBundling one can reduce visual clutter in the image.

The data and methods will be published openly in the near future. The work is a part of the #MobiTwin #EUHorizon project.

For those working in #Python and #mobility or #network data, and who want to get #EdgeBundling to work, check out this repository: https://github.com/xpeterk1/edge-path-bundling/

I tried with our project data and it works nicely. It calculates really fast and uses little resources.

Potentially interesting to @underdarkGIS and @martinfleis

Hey #spatial #R folks, is it possible to extract geometries from #ggplot as files? That is, the point, line, and polygon geometries in the graphs to #geopackage or #shapefile etc.

It is possible with #seaborn and #matplotlib, but that's Python not R. There's a nice and lightning fast #EdgeBundling technique in the newest ggplot, which is very promising for the #visualization of massive #mobility data.

There is also something in #HoloViews but I do not understand that library at all.
