topic_fire(1grass)

🔥 Topic: fire 🔥

bestie, welcome to the fire topic page of the GRASS User's Manual — this is the lil corner of the manual where all the wildfire-flavoured tools live. it's giving chaos, spread, and backtracking 💅 so let's go.

✨ the modules, aka the squad ✨

• r.ros — generates rate of spread raster maps. literally the "how fast is this fire moving" map generator 🏃‍♀️🔥
• r.spread — simulates elliptically anisotropic spread. yes bestie, the fire spreads in a fancy ellipse shape, not a boring circle 🥚✨
• r.spreadpath — recursively traces the least cost path backwards to cells from which the cumulative cost was determined. it walks the whole thing in reverse to find out where the cost came from, no cap 🕵️‍♀️💀

🌸 also!! please go peek at the corresponding keyword fire if you want even more references. there's always more. iykyk.
