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

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.
