#30DayMapChallenge – Day 14: Data Challenge (#OpenStreetMap)
Although this year’s challenge doesn’t include a #vintagemap theme, I decided to bring a bit of history into today’s task.
Using #QGIS, I styled current OpenStreetMap data of #RhodeIsland in the aesthetic of 19th‑century maps. The polygon boundaries were given a Raster Image Fill, with sampled colours directly taken from old maps of the area. To enhance the look, I also used geometry generators to style the water bodies.

#30DayMapChallenge Day 12: Map from 2125
A worst‑case scenario of 2.5 m #SeaLevelRise reshapes the Netherlands. Built in #QGIS with SRTM90 via #OpenTopography, raster image styled polygons, @maptiler.bsky.social satellite raster tiles, and rendered in #3D using Qgis2threejs.
⚠️ Assumes no adaptation. Collapse of the #AMOC (a key ocean current regulating climate) not included.
🔥 Urgency: cut greenhouse gases now to avoid this future.

#30DayMapChallenge Day 8: Urban
On #WorldUrbanismDay, I highlight the most paved municipality in the Netherlands: Krimpen aan den IJssel (43.3%), with Kortland-Noord at nearly 53%.
The Imperviousness Map of NL, made by Friedenau Society for Climate Adaptation Services, derived from AHN LiDAR + BGT, was recently released as a 25 cm COG and used in their Neighbourhood Dashboard: https://buurtdashboard-dev.vercel.app/

#30DayMapChallenge Day 7: Accessibility 🌍✈️
I mapped visa-free travel:
🛫outbound (where citizens can go) and 🛬inbound (who countries let in).It reveals global mobility inequality and rising deglobalisation. Borders are tightening due to geopolitics, trade, migration fears & right-wing politics.
This affects researchers & global collaboration.
📊 Data: 2025 Passport Index

#30DayMapChallenge Day 6: Dimensions Today’s map is a #3D view of Algiers using #QGIS. Elevation = evapotranspiration! I used a #FAO #WaPOR L1 AETI image from 2008 as the elevation model, draped with Google Satellite imagery. Vegetated/agricultural zones rise above urban areas highlighting water dynamics in a striking way. #GIS #RemoteSensing

#30DayMapChallenge Day 5: Earth🌍
I mapped gas fields, mines & earthquakes in the Netherlands. #Groningen’s gas extraction and #Limburg’s mining caused seismic risks, which js now a political issue around damage & compensation. I made this while teaching #QGIS & @merginmaps in Leek (Groningen) for my company #QWAST, hired by #Fervent & #Geo2Meet. The course is part of a reskilling project for GIS jobs. #GIS -
#30DayMapChallenge Day 4 – Data: My Data
🌍 Every year, a colleague asks me to map the geographic distribution of new MSc students in Water & Sustainable Development at IHE Delft. This year, I used #QGIS + #NaturalEarth polygons + #GlobeBuilder plugin to create a #worldmap showing where our students come from. A beautiful dataset that reflects our global classroom! #GIS #OpenData #WaterEducation -
#30DayMapChallenge day 2: Lines 🗺️ Mapped Rotterdam’s watery past through street names with pre- and suffixes like singel, boezem, sloot, vaart, haven, and gedempte. These names trace water infrastructure. Some still flowing, others filled in.

#30DayMapChallenge 2025 day 1: points
Inspired by my stay in Maastricht performing Carl Orff's #CarminaBurana with Brabant Koor & the Jussen Brothers.
Today’s map shows Dutch place names ending in -tricht, -drecht, -trecht—derived from Latin Trajectum, meaning river crossing. #toponyms
Maastricht = Mosa Trajectum.
Made with #QGIS #OpenStreetMap and #vectortiles from @maptiler.bsky.social
🎟️ Still tickets for the amazing concerts weekend: https://jussenmaastricht.nl/
