I finally managed to color countries in my map for the refraction horizontal #sundial
Round map with hour lines, to be placed under 5cm acrylic glass.
The flower's shadow tells solar time and the place where the Sun is overhead. Here off the coast of west Africa, heading to Cuba.
Layout made with a #Python script using #matplotlib and #geopandas

#SãoPaulo map made with #geopandas + #folium + social vulnerabilirty index data from GeoSampa. A heavy but interactive version at https://abav.lugaralgum.com/sketch-a-day/2026/sketch_2026_06_02/mapa.html

The #openriskacademy course Introduction to #GeoJSON has been updated. The update expanded several sections, added examples with #geopandas and fixed some broken links. Enjoy! www.openriskacademy.com/course/view....

The #openriskacademy course Introduction to #GeoJSON has been updated

This course is a CrashProgram (short course) introducing the GeoJSON specification for the encoding of #geospatial features.

The course is at an introductory technical level. It requires some familiarity with data specifications such as JSON and basic knowledge of #Python. The update expanded several sections, added examples with #geopandas and fixed some broken links.

Meh, anyone know how to fix illegal polygons like this in geopandas? I guess there's no fixing this though, this is someone uploading a bad fire perimeter they drew in Google Earth, no doubt. #gis #python #geopandas

@pyohio I'm going strong on my daily creative coding sketches, I usually do them with Python and the #py5 library, and this year it has been all smooth sailing: https://abav.lugaralgum.com/sketch-a-day

Also some #geopandas, #OSMnx and #Folium fun at our local hackerspace here in São Paulo #GaroaHackerClube. I've heard that PyOhio is one of the most welcoming US regional conferences, maybe one day I get the chance to join you :)

Baixamos uns dados do GeoSampa e experimentamos um pouco com #OSMnx e #GeoPandas + #Folium
