DESCRIPTION

       This program burns vector geometries (points, lines, and polygons) into the raster band(s) of a raster
       image. Vectors are read from OGR supported vector formats.

       Note that on the fly reprojection of vector data to the coordinate system of the raster data is only
       supported since GDAL 2.1.0.

       Prior to GDAL 1.8.0, gdal_rasterize could only modify existing raster images. Since 1.8.0, it will 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.

       -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 polygon.
           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 interpolation 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 produce a virtual layer of features to be
           burned in.

       -dialect dialect:
           (GDAL >= 2.1.0) SQL dialect. In some cases can be used to use (unoptimized) OGR SQL instead of the
           native SQL of an RDBMS by passing OGRSQL. Starting with GDAL 1.10, the 'SQLITE' dialect can also be
           used with any datasource.

       -of format:
           (GDAL >= 1.8.0) Select the output format. Starting with GDAL 2.3, if not specified, the format is
           guessed from the extension (previously was GTiff). Use the short format name.

       -a_nodata value:
           (GDAL >= 1.8.0) Assign a specified nodata value to output bands.

       -init value:
           (GDAL >= 1.8.0) Pre-initialize the output image bands with these values. However, 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:
           (GDAL >= 1.8.0) Override the projection for the output file. If not specified, the projection of the
           input vector file will be used if available. 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, complete WKT,
           PROJ.4, EPSG:n or a file containing the WKT.

       -to NAME=VALUE:
           (GDAL >= 2.3.0) set a transformer option suitable to pass to GDALCreateGenImgProjTransformer2(). This
           is used when converting geometries coordinates to target raster pixel space. For example this can be
           used to specify RPC related transformer options.

       -co 'NAME=VALUE':
           (GDAL >= 1.8.0) Passes a creation option to the output format driver. Multiple -co options may be
           listed. See format specific documentation for legal creation options for each format.

       -te xmin ymin xmax ymax :
           (GDAL >= 1.8.0) Set georeferenced extents. The values must be expressed in georeferenced units. If
           not specified, the extent of the output file will be the extent of the vector layers.

       -tr xres yres :
           (GDAL >= 1.8.0) Set target resolution. The values must be expressed in georeferenced units. Both must
           be positive values.

       -tap:
           (GDAL >= 1.8.0) (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:
           (GDAL >= 1.8.0) Set output file size in pixels and lines. Note that -ts cannot be used with -tr

       -ot type:
           (GDAL >= 1.8.0) For the output bands to be of the indicated data type. Defaults to Float64

       -q:
           (GDAL >= 1.8.0) 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 access. As of GDAL 1.8.0, this file will be
           created (or overwritten if it already exists) if the -of, -a_nodata, -init, -a_srs, -co, -te, -tr,
           -tap, -ts, or -ot options are used.

C API

       Starting with GDAL 2.1, this utility is also callable from C with GDALRasterize().

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 elevation 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 order 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
