Ok 4am to 5am is the ranting hour 🤣

...what is it with geospatial engineers and software people and utterly missing the point of rock climbing?

It's not meant to be "made easy by software tools"

Climbing cliffs is a privilege, And extremely hard on multiple levels. Especially unbolted cliffs. Especially new cliffs.

That is the entirety of the point. it is supposed to be hard. Safe outcomes are supposed to arise out of a mentoring driven evolution of multiple skills.

Hey Mapping Fam, Geohipster is seeking map contributions for their 2026 GeoHipster calendar. They aren't on Masto, but you can get more info here https://www.geohipster.com/2026-geohipster-calendar/

A six-sided polygon in light blue with an outline of the continents in red and black plaid fill. The words #geohipster and mapping the world one organic vertex at a time are in white font.

GeoHipster is a collaborative independent online publication on geotechnology and culture, with special focus on open source and open data. We interview geohipsters (the meaning of the term being open to interpretation) from all walks of life and from all corners of the world. We aim to be informative and entertaining. — A six-sided polygon in light blue with an outline of the continents in red and black plaid fill.

In #foss4ge2025 I was talking about Mercator projection, and what is the difference with "Web-Mercator"

These images (at different zoom levels) show a loxodromic curve (at 45° N) in Web-Mercator (EPSG:3857) - that is a straight line in Mercator (EPSG:3395). In red the loxodromic or rhumline. In blue a straight line connecting the endpoints.

(To reproduce it in #QGIS, deselect "Clip features to canvas extent" for the affected layers as discussed in https://github.com/qgis/QGIS/issues/62654)
