NAME - Converts a raster map into vector tiles.


raster, conversion, geometry, vectorization, tiling

SYNOPSIS --help [-svzbtp] input=name output=string type=string [column=name] [x=integer] [y=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]


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

Table of contents

DESCRIPTION vectorizes the input raster map and produces several tiled vector maps covering the current region.

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

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