Usage: gdal_rasterize [-b band]* [-i] [-at]
       [-burn value]* | [-a attribute_name] [-3d]
       [-l layername]* [-where expression] [-sql select_statement]
       [-of format] [-a_srs srs_def] [-co "NAME=VALUE"]*
       [-a_nodata value] [-init value]*
       [-te xmin ymin xmax ymax] [-tr xres yres] [-tap] [-ts width height]
      * [-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/*
*             CInt16/CInt32/CFloat32/CFloat64}]* [-q]
