DESCRIPTION

22       This program burns vector geometries (points, lines, and polygons) into
23       the raster band(s) of a raster image.  Vectors are read from  OGR  sup‐
24       ported vector formats.
25
26       Note that on the fly reprojection of vector data to the coordinate sys‐
27       tem of the raster data is only supported since GDAL 2.1.0.
28
29       -b <band>
30              The band(s) to burn values into.  Multiple -b arguments  may  be
31              used  to burn into a list of bands.  The default is to burn into
32              band 1.  Not used when creating a new raster.
33
34       -i     Invert rasterization.  Burn the fixed burn value,  or  the  burn
35              value  associated  with  the first feature into all parts of the
36              image not inside the provided polygon.
37
38       -at    Enables the ALL_TOUCHED rasterization option so that all  pixels
39              touched  by lines or polygons will be updated, not just those on
40              the line render path, or whose center point is within the  poly‐
41              gon.  Defaults to disabled for normal rendering rules.
42
43       -burn <value>
44              A  fixed  value  to burn into a band for all objects.  A list of
45              -burn options can be supplied, one per band being written to.
46
47       -a <attribute_name>
48              Identifies an attribute field on the features to be used  for  a
49              burn-in value.  The value will be burned into all output bands.
50
51       -3d    Indicates  that  a  burn  value should be extracted from the "Z"
52              values of the feature. Works with points and lines  (linear  in‐
53              terpolation  along  each segment).  For polygons, works properly
54              only if the are flat (same Z value for all vertices).
55
56       -add   Instead of burning a new value, this adds the new value  to  the
57              existing raster.  Suitable for heatmaps for instance.
58
59       -l <layername>
60              Indicates the layer(s) from the datasource that will be used for
61              input features.  May be specified multiple times, but  at  least
62              one layer name or a -sql option must be specified.
63
64       -where <expression>
65              An  optional  SQL  WHERE style query expression to be applied to
66              select features to burn in from the input layer(s).
67
68       -sql <select_statement>
69              An SQL statement to be evaluated against the datasource to  pro‐
70              duce a virtual layer of features to be burned in.  Starting with
71              GDAL 3.7, the @filename syntax can be used to indicate that  the
72              content is in the pointed filename.
73
74       -dialect <dialect>
75              SQL  dialect. In some cases can be used to use (unoptimized) OGR
76              SQL instead of the native SQL of an RDBMS by passing OGRSQL. The
77              "SQLITE" dialect can also be used with any datasource.
78
79              New in version 2.1.
80
81
82       -of <format>
83              Select  the output format. Starting with GDAL 2.3, if not speci‐
84              fied, the format is guessed from the extension  (previously  was
85              GTiff). Use the short format name.
86
87       -a_nodata <value>
88              Assign a specified nodata value to output bands.
89
90       -init <value>
91              Pre-initialize  the  output image bands with these values.  How‐
92              ever, it is not marked as the nodata value in the  output  file.
93              If  only  one  value is given, the same value is used in all the
94              bands.
95
96       -a_srs <srs_def>
97              Override the projection for the output file. If  not  specified,
98              the  projection  of the input vector file will be used if avail‐
99              able. When using this option, no reprojection of  features  from
100              the  SRS  of the input vector to the specified SRS of the output
101              raster, so use only this option to  correct  an  invalid  source
102              SRS.  The <srs_def> may be any of the usual GDAL/OGR forms, com‐
103              plete WKT, PROJ.4, EPSG:n or a file containing the WKT.
104
105       -to NAME=VALUE
106              set   a    transformer    option    suitable    to    pass    to
107              GDALCreateGenImgProjTransformer2(). This is used when converting
108              geometries coordinates to target raster pixel space. For example
109              this can be used to specify RPC related transformer options.
110
111              New in version 2.3.
112
113
114       -co <NAME=VALUE>
115              Many formats have one or more optional creation options that can
116              be used to control particulars about the file created.  For  in‐
117              stance,  the GeoTIFF driver supports creation options to control
118              compression, and whether the file should be tiled.
119
120              The creation options available vary by format driver,  and  some
121              simple  formats  have  no creation options at all. A list of op‐
122              tions supported for a format can be listed  with  the  --formats
123              command  line option but the documentation for the format is the
124              definitive source of information  on  driver  creation  options.
125              See  Raster drivers format specific documentation for legal cre‐
126              ation options for each format.
127
128       -te <xmin> <ymin> <xmax> <ymax>
129              Set georeferenced extents. The values must be expressed in  geo‐
130              referenced  units.   If  not specified, the extent of the output
131              file will be the extent of the vector layers.
132
133       -tr <xres> <yres>
134              Set target resolution. The values must be expressed in georefer‐
135              enced units.  Both must be positive values.
136
137       -tap   (target  aligned  pixels) Align the coordinates of the extent of
138              the output file to the values of the -tr, such that the  aligned
139              extent includes the minimum extent.  Alignment means that xmin /
140              resx, ymin / resy, xmax / resx and ymax / resy are integer  val‐
141              ues.
142
143       -ts <width> <height>
144              Set  output  file size in pixels and lines. Note that -ts cannot
145              be used with -tr
146
147       -ot <type>
148              Force the output bands to be of the  indicated  data  type.  De‐
149              faults to Float64
150
151       -optim {[AUTO]/VECTOR/RASTER}}
152              Force  the  algorithm  used  (results are identical). The raster
153              mode is used in most cases and optimise  read/write  operations.
154              The vector mode is useful with a decent amount of input features
155              and optimise the CPU use. That mode have to be used  with  tiled
156              images  to  be efficient. The auto mode (the default) will chose
157              the algorithm based on input and output properties.

159              New in version 2.3.
160
161
162       -oo <NAME=VALUE>
163              New in version 3.7.
164
165
166              Source dataset open option (format specific)
167
168       -q     Suppress progress monitor and other non-error output.
169
170       <src_datasource>
171              Any OGR supported readable datasource.
172
173       <dst_filename>
174              The GDAL supported output file.  Must support  update  mode  ac‐
175              cess.   This  file will be created (or overwritten if it already
176              exists):option:-of, -a_nodata, -init,  -a_srs,  -co,  -te,  -tr,
177              -tap, -ts, or -ot options are used.
178
179       The  program  create  a  new  target  raster image when any of the -of,
180       -a_nodata, -init, -a_srs, -co, -te, -tr, -tap, -ts, or -ot options  are
181       used.   The  resolution  or size must be specified using the -tr or -ts
182       option for all new rasters.  The target raster will be  overwritten  if
183       it already exists and any of these creation-related options are used.
184

EXAMPLE

192       The  following  would burn all polygons from mask.shp into the RGB TIFF
193       file work.tif with the color red (RGB = 255,0,0).
194
195          gdal_rasterize -b 1 -b 2 -b 3 -burn 255 -burn 0 -burn 0 -l mask mask.shp work.tif
196
197       The following would burn all "class A" buildings into the output eleva‐
198       tion file, pulling the top elevation from the ROOF_H attribute.
199
200          gdal_rasterize -a ROOF_H -where "class='A'" -l footprints footprints.shp city_dem.tif
201
202       The  following  would  burn  all polygons from footprint.shp into a new
203       1000x1000 rgb TIFF as the color red.  Note that -b is not used; the or‐
204       der of the -burn options determines the bands of the output raster.
