GRASS GIS manual: r.to.vect.tiled

NAME

r.to.vect.tiled - Converts a raster map into vector tiles.

KEYWORDS

raster, conversion, geometry, vectorization, tiling

SYNOPSIS

r.to.vect.tiled

r.to.vect.tiled --help

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

Flags:

-s: Smooth corners of linear features
-v: Use raster values as categories instead of unique sequence (CELL only)
-z: Write raster values as z coordinate; Table is not created. Currently supported only for points.
-b: Do not build vector topology; Recommended for massive point conversion
-t: Do not create attribute table
-p: Patch the tiles
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=name [required]: Name of input raster map
output=string [required]: Output base name
type=string [required]: Feature type; Options: point, line, area
column=name: Name of attribute column to store value; Name must be SQL compliant; Default: value
x=integer: Number of tiles in x direction; Default: 2
y=integer: Number of tiles in y direction; Default: 2

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.
