🗺️ #30DayMapChallenge – Jour 4 : My Data
Thème du jour : Cartographier quelque chose de personnel.

De mes débuts au gymnase de l'Arche à Bethoncourt jusqu’au chaudron du gymnase des Brèques à Courseulles-sur-Mer, chaque point sur la carte raconte une période, une équipe, des rencontres et beaucoup de bons souvenirs. 😅

🏃 Mon parcours : BeexVA Handball, Belfort, Gray, Carpiquet, Courseulles sur mer

River Network Routing And Discharge Partitioning On A Multichannel River Network
--
https://doi.org/10.1029/2025WR041417 <-- shared paper
--
"... KEY POINTS:
• River multifurcation pathways were identified in a vector river network globally
• A multifurcation scheme was added to a river network routing model to split river discharge at divergences
• Accounting for multichannels improved discharge accuracy and resulted in earlier arrival of flood waves downstream of divergences…”

@cargot_robbie I've posted an updated demo video of my QGIS "Walk Potential" plugin and published the code to Gitlab.

The latest version uses a free isochrone service by default. No dependencies, subscriptions, or licenses required!

Demo: https://urbanists.video/w/kNht44gXqiN2w95ZhxQRVW
Code: https://gitlab.com/markstos/qgis-walk-potential
Example of how a pedestrian demand metric is useful for finding locations to prioritize sidewalk funding: https://mark.stosberg.com/toolkit-for-sidewalk-location-priority/
