r.to.vect.tiled

Converts a raster map into vector tiles.

Command linePython (grass.script)

r.to.vect.tiled [-svzbtp] input=name output=string type=string [column=name] [x=integer] [y=integer] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

r.to.vect.tiled input=name output=string type=string

grass.script.run_command("r.to.vect.tiled", input, output, type, column="value", x=2, y=2, flags=None, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.to.vect.tiled", input="name", output="string", type="string")

DESCRIPTION

r.to.vect.tiled vectorizes the input raster map and produces several tiled vector maps covering the current region.

Vectorizing a large raster map with r.to.vect can require a lot of memory. In these cases, r.to.vect.tiled can reduce memory usage by vectorizing each tile separately.

The tiles are optionally patched together with the -p flag.
