.. only:: html Vector conversion ================= .. only:: html .. contents:: :local: :depth: 1 .. _gdalconvertformat: Convert format -------------- Converts any OGR-supported vector layer into another OGR-supported format. This algorithm is derived from the `ogr2ogr utility `_ . Parameters .......... .. list-table:: :header-rows: 1 :widths: 20 20 20 40 :stub-columns: 0 * - 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 ....... .. list-table:: :header-rows: 1 :widths: 20 20 20 40 :stub-columns: 0 * - Label - Name - Type - Description * - **Converted** - ``OUTPUT`` - [vector: any] - The output vector layer .. _gdalrasterize: 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``: :menuselection:`Raster --> Conversion` Parameters .......... .. list-table:: :header-rows: 1 :widths: 20 20 20 40 :stub-columns: 0 * - 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 :ref:`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.
