💖 topic_sampling(1grass) 💖

okay bestie, welcome to the GRASS User's Manual page for topic_sampling(1grass) — aka the ✨sampling✨ topic. it's giving "everything you need when you wanna grab values at specific points" energy and honestly? iconic.

🌸 THE TOPIC: sampling 🌸

no cap, this is a topic page — a curated little squad of modules that all do the sampling thing. sampling = asking "hey what's the value right here?" and getting an answer back. let's meet the whole friend group 🫶

• d.where — figures out the geographic coordinates that go with point locations you gave it in display coordinates. like, translating screen vibes into map vibes 💅
• r.random.cells — generates random cell values, but make it spatially dependent. so the randomness has a friend group, not just chaos 🌈
• r.random — creates raster cells or vector points, randomly placed. scattering them like confetti 🎀
• t.rast.what — samples a space time raster dataset at specific vector point coordinates and writes the output to stdout, and you get to pick from different layouts. three cheers for options 👑
• t.sample — samples the input space time dataset(s) with a sample space time dataset and prints the result to stdout.
• t.vect.observe.strds — observes specific locations in a space time raster dataset over a period of time, using vector points. it's watching. main character surveillance 🦋
• t.vect.what.strds — stores raster map values at the spatial and temporal positions of vector points, saved as vector attributes.
• v.random — generates random 2D/3D vector points. yes, three dee, she's versatile 💜
• v.sample — samples a raster map at vector point locations.
• v.what.rast — uploads raster values at the positions of vector points to the table.
• v.what.rast3 — uploads 3D raster values at the positions of vector points to the table.
• v.what.vect — uploads vector values at the positions of vector points to the table.
