Day 42. Rivers as flow networks ๐
South America's river systems as interconnected flow networks.
Using HydroSHEDS data, the focus is on hierarchy: streams โ tributaries โ major rivers โ ocean. Multiple scales reveal both continental structure and local complexity.
The visualization moves through zoom levels in a rotating Three.js carousel.

#100DayMapChallenge Day 42/100
Create a Catchment Map in QGIS in 10 Minutes
#30DayMapChallenge Day 17: A New Tool
๐ ๏ธ Tried #JupyterGIS, a #Python-based mapping tool in #JupyterLab, for mapping transboundary aquifers using open data from #IGRAC + #HydroSHEDS basins on an #OSM raster backdrop. Whatโs great? Real-time map+code collaboration, live annotations, and reproducible workflows. A promising lightweight, open alternative to traditional #GIS!
#30DayMapChallenge โ Day 13: 10 minute map
Map of the #Mara River Basin made in #QGIS with #HydroSHEDS #opendata and @maptiler.bsky.social #vectortiles.

#30DayMapChallenge Day 28: The Blue Planet ๐
I've created globes with rivers from #HydroSHEDS & bathymetry from Ocean RGB raster tile in #QGIS using the #MapTiler & Globe Builder plugins. Check out the beauty of our planet's waterways & ocean depths! ๐๐
