💖 t.rast3d.mapcalc 💖

okay bestie, listen up — this is the GRASS User's Manual page for t.rast3d.mapcalc (that (1grass) bit just means she's a GRASS module, no biggie). She does r3.mapcalc math on maps from sampled space time 3D raster datasets. voxels. 3D. iconic behavior honestly. ✨

🎀 KEYWORDS 🎀

temporal, algebra, raster3d, voxel, time

🌸 SYNOPSIS 🌸

t.rast3d.mapcalc
t.rast3d.mapcalc --help
t.rast3d.mapcalc [-ns] inputs=name[,name,...] expression=string
[method=name[,name,...]]  output=name basename=string  [nprocs=integer]
[--overwrite]  [--help]  [--verbose]  [--quiet]  [--ui]

🦋 Flags

  • -n — register the Null maps, periodt 💅
  • -s — check the spatial topology of temporally related maps and process only the ones that are spatially related 🫶
  • --overwrite — let those output files bulldoze whatever's already sitting there. existing files? gone. bye 🫢
  • --help — prints the usage summary, for when you're like "wait what" 😭
  • --verbose — verbose module output, she's chatty now 💬
  • --quiet — quiet module output, she's giving mystery 🕶️
  • --ui — force the GUI dialog to pop up, main character entrance 🌈

🍓 Parameters

  • inputs=name[,name,...] [required] — the name(s) of the input space time raster3d datasets you're feeding her 🧺
  • expression=string [required] — the r3.mapcalc expression that gets applied to each time step of the sampled data. this is the whole point, no pressure 💅
  • method=name[,name,...] — how you wanna sample the input dataset
    • Options: start, during, overlap, contain, equal, follows, precedes
    • Default: during,overlap,contain,equal
  • output=name [required] — name of the output space time raster3d dataset 🎁
  • basename=string [required] — basename of the new generated output maps
    • heads up: a numerical suffix separated by an underscore gets attached to it so it can create a unique identifier. it's her little signature 🖊️
  • nprocs=integer — number of r3.mapcalc processes to run in parallel
    • Default: 1

✨ DESCRIPTION ✨

okay so t.rast3d.mapcalc gives you exact the same functionality as t.rast.mapcalc, except it's for space time 3D raster datasets. so if you need the docs, go read t.rast.mapcalc, she's got you covered 📚

and ngl? she's just a simple wrapper for r3.mapcalc that got enhanced with temporal functions. glow up fr fr 🔥
