💖 t.upgrade — the GRASS GIS glow-up page 💖

okay bestie, you found a page in the GRASS GIS User's Manual and it's literally called t.upgrade(1). it's short, it's sweet, it's giving "small module, big consequences". let's get into it 🦋

✨ NAME ✨

t.upgrade — upgrades the version of the temporal database.

like, it takes your temporal database and drags it into the current era. no cap.

🏷️ KEYWORDS 🏷️

temporal, metadata, time

(so if you were searching for any of those three words, hi, you're in the right place 💅)

🌸 SYNOPSIS 🌸

t.upgrade
t.upgrade --help
t.upgrade  [--help]  [--verbose]  [--quiet]  [--ui]

that's it. that's the whole vibe. no required arguments, no positional drama, just flags.

🎀 Flags 🎀

  • --help — prints the usage summary. the "wait what does this do again" button.
  • --verbose — verbose module output. it will talk to you. a lot. main character energy.
  • --quiet — quiet module output. it will not talk to you. mysterious. elusive. iconic.
  • --ui — forces the GUI dialog to launch. for when you want a lil window instead of the terminal. 🙈

💫 DESCRIPTION 💫

okay so here's the tea. the t.upgrade module upgrades the temporal database in the current mapset from version 2 (which is the default in GRASS 7) to version 3 (which is the default in GRASS 8).

and why should you care about version 3, you ask? because version 3 introduces semantic label support. 🏷️✨ that's the whole glow-up. if you wanna know the deets on that, go look at i.band.library — it's all explained there.

heads up bestie: this is a one-way kind of thing conceptually — you're moving your temporal database forward a version. the module does exactly this and nothing else. no extra sprinkles, no secret options. 🫶

🌈 EXAMPLE 🌈

t.upgrade

yeah. that's the example. that's the whole example. you run it. it upgrades. slay. 💅
