✨ surface, but make it a vibe ✨

okay bestie, welcome to topic_surface from the GRASS User's Manual 💖 this is your little group chat of modules that all live under the surface topic — interpolation, random surfaces, contour stuff, all of it. no cap, this whole page is just the guest list. let's go 🦋

🌸 the modules (the main characters) 🌸

  • r.contour — takes a raster map and spits out a vector map of the contours you asked for. lines on lines on lines ✨
  • r.fill.stats — fills up the 'no data' cells (NULLs) in a raster map with interpolated values (IDW), and it does it fast. obsessed 🏃♀️
  • r.fillnulls — the no-data areas in your raster maps? filled. using spline interpolation. glow up complete 💅
  • r.random.surface — generates random surface(s) that have spatial dependence. randomness but make it ✨spatially aware✨
  • r.resamp.bspline — bilinear or bicubic spline interpolation, with Tykhonov regularization. fancy girly behavior 🎀
  • r.surf.area — prints an estimation of the surface area for a raster map. how much area bestie 😭
  • r.surf.contour — generates a surface raster map out of rasterized contours. contour → surface, the pipeline of dreams 🌈
  • r.surf.fractal — creates a fractal surface of a given fractal dimension. it's giving infinite coastline energy 🌀
  • r.surf.gauss — makes a raster map using a gaussian random number generator. normal distribution slay 🔔
  • r.surf.idw — surface interpolation from raster point data via Inverse Distance Squared Weighting. say that three times fast 🫶
  • r.surf.random — produces a raster surface map of uniform random deviates with a defined range. chaos, but within bounds 👑
  • v.surf.bspline — bicubic or bilinear spline interpolation with Tykhonov regularization, vector edition. she's back and she's a v. this time 💜
  • v.surf.idw — surface interpolation from vector point data via Inverse Distance Squared Weighting. same energy, vector flavor ⭐
  • v.surf.rst — surface interpolation from a vector points map by splines. rst = regularized spline with tension, iykyk 🧚
side note bestie: peep the corresponding keyword surface if you want even more references on this topic 💌
