d.where | Identifies the geographic coordinates associated with point locations given in display coordinates.
r.random.cells | Generates random cell values with spatial dependence.
r.random | Creates a raster map layer and vector point map containing randomly located points.
t.rast.what | Sample a space time raster dataset at specific vector point coordinates and write the output to stdout using different layouts
t.sample | Samples the input space time dataset(s) with a sample space time dataset and print 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.
t.vect.what.strds | Stores raster map values at spatial and temporal positions of vector points as vector attributes.
