Por algún motivo que no logro depurar, la función `distance()` de #GeoPandas me sigue devolviendo valores en grados, aún cuando estoy asignando un CRS proyectado a los archivos que estoy tratando de medir :catThink: .

📚 Look what GeoPandas has for the geospatial community! An academic paper 📄 covering the history ⌛ of the project, its core data structures and its influence on the wider geospatial Python ecosystem 🐍🗺️.
It is open access 🔓 and offers a useful reference for researchers and others working with GeoPandas.
#TodayILearned that if you do a .dissolve() on a #geopandas #GeoDataFrame "by" a certain column, it becomes "an index" thus, kind of hidden. You can regain access to it with .reset_index()
Also, when merging two gdfs it can be useful to first select just the relevant columns from one of them, in order to preserve the geometry column of the other...
...at least this is how it looks like how it worked for me...
I finally managed to color countries in my map for the refraction horizontal #sundial

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 :)

QGIS to (Geo)Pandas – part 3
The journey continues: QgsArrowIterator is now merged, making it possible to iterate over QgsFeatures as Arrow batches.

The #Volcanic Isles . A brief history of volcanism across The British Isles.
Quite pleased with how this one turned out.
Location of volcanoes taken from wikipedia (spotted a mistake and got to make an edit to wikipedia in the process); fault lines from the #BGS 625k bedrock dataset and the IE GSI 500k Bedrock Geology for Ireland. Font: League-Spartan by the League of Moveable Type.
#requests, #pandas and #geopandas for scraping and wrangling.#scipy for making the proximity surface (that's the colour scheme), #matplotlib for plotting. With all labeling done manually in #inkscape.
EDIT: I've been kindly and helpfully informed that (a) Ben Nevis' age is closer to 399 Ma; (b) some are missing; (c) others perhaps shouldn't be there; (d) it's complicated. So, maybe don't use this map to make any strategic decisions.

Sous quel climat vivez-vous ?
Dès l'Antiquité, on définissait les climats comme des bandes géographiques distinctes, selon la durée du jour le plus long de l'année.
Sur l'équateur : 1er climat - durée 12h.
Sud de la France : 7e climat - durée 15h. etc.
À partir du cercle polaire, le jour le plus long dure 24h !
Fun fact : dans l'Antiquité, on ne définissait les climats que jusqu'à la latitude 50° car au-delà on pensait la terre inhabitable 😁
