✨ Topic: reclassification ✨

okay bestie, welcome to the reclassification corner of GRASS GIS 💅 this is where maps get their categories remixed — like a glow-up but for your attribute values 🎀

Here's the lineup:

• r.reclass — takes a raster map and reclassifies it based on its category values. iconic behaviour honestly.
• v.reclass — changes the vector category values of an existing vector map, following either the results of SQL queries or a value sitting in a column of the attribute table. it's giving "your categories, but make it SQL" 💖
