How to lie with maps. I suddenly remembered quite late this evening that it's already November! Have you ever had a lot of points and wondered how to best display them? Here is an webmap of gun deaths for Cook County, Illinois playing with three approaches with varying levels of deception. #30DayMapChallenge #Points

#30DayMapChallenge Day 1: Points
I mapped the tiny pene-exclave of Point Roberts, accessible only by water or by crossing an international boundary. I chose a modified antique style. I enjoy that this little bit of the US is nesteled by our 🇨🇦 neighbors.
#30daymapchallenge Day 17 (collaboration): OpenStreetMap Nodes of Leipzig Zentrum, coloured by user who edited them most recently. The way I see it, every map using OSM-Data is collaborative, but it's hard to show just how much of a collaboration it is. As of March 2025 there are 452 different users who last edited a node in this area, disregarding ways and relations. Colours were chosen at random by QGIS.
Incredible writeup from @pinakographos on how to make stylised terrain relief. Just in time for #30DayMapChallenge !

It's been a long journey (over year since I began), but there's finally now a first public release of the oblique hachures method. With many thanks to @SouthArrowMaps, who significantly refined the methodology from what I began with.

Just updated my vault template to show how I use the new Maps feature for #Obsidian Bases. Super useful for travel planning.
