#30DayMapChallenge Day 4: Green Friday Trees from 6 Dutch cities reconstructed from point clouds using our software Adtree (github.com/tudelft3d/AdTr…). One was tilted by the strong Dutch wind. Can you guess which one?

#30DayMapChallenge Day 6: Network Cycle lanes in South Holland, the Netherlands. Did you know that you can just as easily cycle between cities as you can inside them? Generated using github.com/gboeing/osmnx, a python library for spatial data analysis from OpenStreetMap

#30DayMapChallenge Day 7: Raster Summer sizzle in Amsterdam. Surface temperature on hot summer days (2018-2022), expressed as the difference from the mean (~28°C). Can you spot the hottest/coolest areas? 😎

#30DayMapChallenge Day 15: Food and drinks The most important map in our office is from the fridge to the eating table 😊 We used novel-view synthesis method nerfacto from nerfstudio to render the path to our fridge!

#30DayMapChallenge Day 16: Minimal The minimal elements for a good map! We did go a bit lazy on this one because we are preparing for the second half of the challenge 😇

#30DayMapChallenge Day 18: Blue Friday 3DBAG (3dbag.nl) from a #RoyalDelftBlue perspective. Looking forward to getting this ceramic tile from Royal Delft!

#30DayMapChallenge Day 22: NULL Nerding out on the National Dutch Amersfoort / RD New map projection system #EPSG28992 #QGIS

#30DayMapChallenge Day 28: 3D Why would you want 3D building models? This #blender render of our 3dbag.nl dataset showcases three possible answers to that question!

#30DayMapChallenge Day 29: "Out of my comfort zone" This is a 4D polychoron, composed of two LoDs of a building, projected in 3D space and then rendered in 2D. Do you see it? 🤓 The map is created with azul4d: github.com/kenohori/azul4d

#30DayMapChallenge Day 30: Remix For the remix, we made a GIF of all of our maps. Sorry we think we’re just tired after this intensive month... and we need a break until the #30DayMapChallenge2023 !

New paper: Inferring the number of floors for residential buildings by Roy E, Pronk M, Agugiaro G & Hugo Ledoux #ijgis tandfonline.com/doi/full/10.10…

Delft here we are. Awaiting our first in-person meetings that will take place from 16-17th of February 2023 at TU Delft. A lot of discussion, work and fun are in front of us.
