Note: This document is for an older version of GRASS GIS that will be discontinued soon. You should upgrade, and read the current manual page.

Topic: sampling

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.
v.random	Generates random 2D/3D vector points.
v.sample	Samples a raster map at vector point locations.
v.what.rast	Uploads raster values at positions of vector points to the table.
v.what.rast3	Uploads 3D raster values at positions of vector points to the table.
v.what.vect	Uploads vector values at positions of vector points to the table.
