NAMEgdal_rasterize - gdal_rasterize burns vector geometries into a raster
SYNOPSISUsage: gdal_rasterize [-b band] [-i] [-at] [-burn value] | [-a attribute_name] [-3d] [-l layername]* [-where expression] [-sql select_statement] <src_datasource> <dst_filename>
DESCRIPTIONThis 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 the vector data must in the same coordinate system as the raster data, on the fly reprojection is not provided. -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. -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 a polygon. -at: Enables the ALL_TOUCHED rasterization option so that all pixels touched by lines or polygons will be updated not just those one 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. These values are adjusted by the burn value given by '-burn value' or '-a attribute_name' if provided. As of now, only points and lines are drawn in 3D. -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. src_datasource: Any OGR supported readable datasource. dst_filename: The GDAL supported output file. Must support update mode access. Currently gdal_rasterize cannot create new output files though that may be added eventually.
EXAMPLEThe 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
