topic_projection(1grass)

🌸 Topic: projection 🌸

okay bestie, so this is topic_projection(1grass) — it's not a command, it's a vibe check of a topic page 💅. It's the GRASS User's Manual's little roundup of everything projection-related, so if your brain goes "wait, which tool do I use to re-project stuff??" you land here and it's giving ✨ organized ✨.

Projections are literally the whole personality of GIS. You got coordinates living in one vibe, and you need them living in another vibe, and these four commands are your besties for that. Periodt. 🦋
