r.to.vect.tiled - GRASS GIS manual

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

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.
