💖 d.to.rast — the manual, but make it cute 💖

okay so bestie, we're in the GRASS GIS User's Manual, section d.to.rast(1), and this lil module is literally the screenshot button of the display world. let's get into it 🫶

✨ NAME ✨

d.to.rast — Saves the contents of the active display monitor to a raster map. that's it, that's the whole job, and she does it flawlessly 💅

🏷️ KEYWORDS 🏷️

display, export, raster

🌸 SYNOPSIS 🌸

d.to.rast
d.to.rast --help
d.to.rast output=name  [--overwrite]  [--help]  [--verbose]  [--quiet]
[--ui]

🎀 Flags 🎀

  • --overwrite — Allow output files to overwrite existing files (yes, she will absolutely clobber what's already there if you let her, so be careful 👀)
  • --help — Print usage summary
  • --verbose — Verbose module output
  • --quiet — Quiet module output
  • --ui — Force launching GUI dialog

🦋 Parameters 🦋

  • output=name [required] — Name for output raster map

💜 DESCRIPTION 💜

so d.to.rast saves the content of the currently selected monitor into a raster map. the active monitor can be selected with d.mon. and plot twist — d.to.rast can be run from the GUI Console tab, too. no cap.

💀 important vibe check: this module is not sensitive to computational region settings. she does not care about your region, she just copies the monitor. periodt.

⭐ EXAMPLE ⭐

bestie we're gonna combine different raster and vector map layers to create a composite layer which can be draped over elevation in 3D view. iconic behavior, honestly.

First, we add a couple of maps to layer manager:

g.region raster=elevation
d.rast map=elevation
d.rast map=lakes
d.vect map=roadsmajor width=4
d.vect map=roadsmajor width=2 color=yellow
# create a raster map from the display
d.to.rast output=composite

Then uncheck all layers except for elevation and switch to 3D view. In Data tab, set color map to the newly created composite map. chef's kiss 🧚

Figure: Raster map created by d.to.rast draped over digital elevation model.
