DESCRIPTION
This program burns vector geometries (points, lines, and polygons) into
the raster band(s) of a raster image. Vectors are read from OGR sup-
ported vector formats.
Note that on the fly reprojection of vector data to the coordinate sys-
tem of the raster data is only supported since GDAL 2.1.0.
-b <band>
The band(s) to burn values into. Multiple -b arguments may be
used to burn into a list of bands. The default is to burn into
band 1. Not used when creating a new raster.
-i Invert rasterization. Burn the fixed burn value, or the burn
value associated with the first feature into all parts of the
image not inside the provided polygon.
-at Enables the ALL_TOUCHED rasterization option so that all pixels
touched by lines or polygons will be updated, not just those on
the line render path, or whose center point is within the poly-
gon. Defaults to disabled for normal rendering rules.
-burn <value>
A fixed value to burn into a band for all objects. A list of
-burn options can be supplied, one per band being written to.
-a <attribute_name>
Identifies an attribute field on the features to be used for a
burn-in value. The value will be burned into all output bands.
-3d Indicates that a burn value should be extracted from the "Z"
values of the feature. Works with points and lines (linear in-
terpolation along each segment). For polygons, works properly
only if the are flat (same Z value for all vertices).
-add Instead of burning a new value, this adds the new value to the
existing raster. Suitable for heatmaps for instance.
-l <layername>
Indicates the layer(s) from the datasource that will be used for
input features. May be specified multiple times, but at least
one layer name or a -sql option must be specified.
-where <expression>
An optional SQL WHERE style query expression to be applied to
select features to burn in from the input layer(s).
-sql <select_statement>
An SQL statement to be evaluated against the datasource to pro-
duce a virtual layer of features to be burned in.
-dialect <dialect>
SQL dialect. In some cases can be used to use (unoptimized) OGR
SQL instead of the native SQL of an RDBMS by passing OGRSQL. The
"SQLITE" dialect can also be used with any datasource.
New in version 2.1.
-of <format>
Select the output format. Starting with GDAL 2.3, if not speci-
fied, the format is guessed from the extension (previously was
GTiff). Use the short format name.
-a_nodata <value>
Assign a specified nodata value to output bands.
-init <value>
Pre-initialize the output image bands with these values. How-
ever, it is not marked as the nodata value in the output file.
If only one value is given, the same value is used in all the
bands.
-a_srs <srs_def>
Override the projection for the output file. If not specified,
the projection of the input vector file will be used if avail-
able. When using this option, no reprojection of features from
the SRS of the input vector to the specified SRS of the output
raster, so use only this option to correct an invalid source
SRS. The <srs_def> may be any of the usual GDAL/OGR forms, com-
plete WKT, PROJ.4, EPSG:n or a file containing the WKT.
-to NAME=VALUE
set a transformer option suitable to pass to GDALCreateGenImg-
ProjTransformer2(). This is used when converting geometries co-
ordinates to target raster pixel space. For example this can be
used to specify RPC related transformer options.
New in version 2.3.
-co <NAME=VALUE>
Many formats have one or more optional creation options that can
be used to control particulars about the file created. For in-
stance, the GeoTIFF driver supports creation options to control
compression, and whether the file should be tiled.
The creation options available vary by format driver, and some
simple formats have no creation options at all. A list of op-
tions supported for a format can be listed with the --formats
command line option but the documentation for the format is the
definitive source of information on driver creation options.
See raster_drivers format specific documentation for legal cre-
ation options for each format.
-te <xmin> <ymin> <xmax> <ymax>
Set georeferenced extents. The values must be expressed in geo-
referenced units. If not specified, the extent of the output
file will be the extent of the vector layers.
-tr <xres> <yres>
Set target resolution. The values must be expressed in georefer-
enced units. Both must be positive values.
-tap (target aligned pixels) Align the coordinates of the extent of
the output file to the values of the -tr, such that the aligned
extent includes the minimum extent.
-ts <width> <height>
Set output file size in pixels and lines. Note that -ts cannot
be used with -tr
-ot <type>
Force the output bands to be of the indicated data type. De-
faults to Float64
-optim {[AUTO]/VECTOR/RASTER}}
Force the algorithm used (results are identical). The raster
mode is used in most cases and optimise read/write operations.
The vector mode is useful with a decent amount of input features
and optimise the CPU use. That mode have to be used with tiled
images to be efficient. The auto mode (the default) will chose
the algorithm based on input and output properties.
New in version 2.3.
-q Suppress progress monitor and other non-error output.
<src_datasource>
Any OGR supported readable datasource.
<dst_filename>
The GDAL supported output file. Must support update mode ac-
cess. This file will be created (or overwritten if it already
exists):option:-of, -a_nodata, -init, -a_srs, -co, -te, -tr,
-tap, -ts, or -ot options are used.
The program create a new target raster image when any of the -of,
-a_nodata, -init, -a_srs, -co, -te, -tr, -tap, -ts, or -ot options are
used. The resolution or size must be specified using the -tr or -ts
option for all new rasters. The target raster will be overwritten if
it already exists and any of these creation-related options are used.
C API
This utility is also callable from C with GDALRasterize().
New in version 2.1.
EXAMPLE
The following would burn all polygons from mask.shp into the RGB TIFF
file work.tif with the color red (RGB = 255,0,0).
gdal_rasterize -b 1 -b 2 -b 3 -burn 255 -burn 0 -burn 0 -l mask mask.shp work.tif
The following would burn all "class A" buildings into the output eleva-
tion file, pulling the top elevation from the ROOF_H attribute.
gdal_rasterize -a ROOF_H -where 'class="A"' -l footprints footprints.shp city_dem.tif
The following would burn all polygons from footprint.shp into a new
1000x1000 rgb TIFF as the color red. Note that -b is not used; the or-
der of the -burn options determines the bands of the output raster.
gdal_rasterize -burn 255 -burn 0 -burn 0 -ot Byte -ts 1000 1000 -l footprints footprints.shp mask.tif
