✨ topic_classification ✨

okay bestie, welcome to the GRASS User's Manual 💖 this is the topic page for topic_classification and it's literally the group chat for everything classification-coded. if you've ever wanted to sort pixels, cells or attributes into little boxes and give them names, you're in the right place. no cap. 👑

🌈 TOPIC: CLASSIFICATION 🌈

classification is the vibe where you teach the computer to look at data and go "oh that's forest", "oh that's water", "oh that's a mystery", and honestly? iconic. here's the whole squad of tools that do it 👇

  • i.cluster — generates spectral signatures for land cover types in an image using a clustering algorithm. it just... groups stuff that looks alike. unsupervised queen 💅
  • i.gensig — generates statistics for i.maxlik from a raster map. it's the lil' prepper that feeds i.maxlik its snack 🍓
  • i.gensigset — generates statistics for i.smap from raster map. same energy, but this one's for i.smap.
  • i.maxlik — classifies the cell spectral reflectances in imagery data. it looks at how shiny each cell is and picks a label for it ✨
  • i.signatures — manage imagery classification signature files. like a lil' filing cabinet for your signatures 🎀
  • i.smap — performs contextual image classification using sequential maximum a posteriori (SMAP) estimation. yes that's the whole name, no we're not abbreviating it, it ate 🔥
  • v.class — classifies attribute data, e.g. for thematic mapping. vector data deserves a glow-up too 🦋
also! there's a whole corresponding keyword called classification with even more references if you want to go deeper. iykyk.

💜 THE SIGN-OFF 💜

that's the whole page bestie! this beauty is from the GRASS 8.5.0 Reference Manual, © 2003-2026, brought to you by the one and only GRASS Development Team 👑🫶 and yes, topic_classification(1grass) is the name, don't forget it. periodt. 💅🌸
