Vector conversion

Convert format

Converts any OGR-supported vector layer into another OGR-supported format.

This algorithm is derived from the ogr2ogr utility .

Parameters

Label	Name	Type	Description
Input layer	INPUT	[vector: any]	Input vector layer
Additional creation options (optional)	OPTIONS	[string] Default: ‚‘ (no additional options)	Additional GDAL creation options.
Converted	OUTPUT	[vector: any]	Specification of the output vector layer. One of: Save to a Temporary File Save to File… The file encoding can also be changed here. For Save to File, the output format has to be specified. All GDAL vector formats are supported. For Save to a Temporary File the QGIS default vector format will be used.

Outputs

Label	Name	Type	Description
Converted	OUTPUT	[vector: any]	The output vector layer

Rasterize (vector to raster)

Converts vector geometries (points, lines and polygons) into a raster image.

This algorithm is derived from the GDAL rasterize utility .

Default menu: Raster ‣ Conversion

Parameters

Label	Name	Type	Description
Input layer	INPUT	[vector: any]	Input vector layer
Field to use for a burn-in value Optional	FIELD	[tablefield: numeric]	Defines the attribute field from which the attributes for the pixels should be chosen
A fixed value to burn Optional	BURN	[number] Default: 0.0	A fixed value to burn into a band for all features.
Output raster size units	UNITS	[enumeration] Default: 0	Units to use when defining the output raster size/resolution. One of: 0 — Pixels 1 — Georeferenced units
Width/Horizontal resolution	WIDTH	[number] Default: 0.0	Sets the width (if size units is „Pixels“) or horizontal resolution (if size units is „Georeferenced units“) of the output raster. Minimum value: 0.0.
Height/Vertical resolution	HEIGHT	[number] Default: 0.0	Sets the height (if size units is „Pixels“) or vertical resolution (if size units is „Georeferenced units“) of the output raster.
Output extent	EXTENT	[extent]	Extent of the output raster layer. If the extent is not specified, the minimum extent that covers the selected reference layer(s) will be used.
Assign a specified nodata value to output bands Optional	NODATA	[number] Default: 0.0	Assigns a specified nodata value to output bands
Additional creation options Optional	OPTIONS	[string] Default: ‚‘	For adding one or more creation options that control the raster to be created (colors, block size, file compression…). For convenience, you can rely on predefined profiles (see GDAL driver options section).
Output data type	DATA_TYPE	[enumeration] Default: 5	Defines the format of the output raster file. Options: 0 — Use input layer data type 1 — Byte 2 — Int16 3 — UInt16 4 — UInt32 5 — Int32 6 — Float32 7 — Float64 8 — CInt16 9 — CInt32 10 — CFloat32 11 — CFloat64
Pre-initialize the output image with value Optional	INIT	[number]	Pre-initializes the output image bands with this value. Not marked as the nodata value in the output file. The same value is used in all the bands.
Invert rasterization	INVERT	[boolean] Default: False	Burns the fixed burn value, or the burn value associated with the first feature into all parts of the image not inside the provided polygon.
Rasterized	OUTPUT	[raster] Default: ‚[Save to temporary file]‘	Specification of the output raster layer. One of: Save to a Temporary File Save to File… The file encoding can also be changed here For Save to File, the output format has to be specified. All GDAL raster formats are supported. For Save to a Temporary File the QGIS default raster format will be used.
