Burn or rasterize vectors onto GeoTiff images

Once a while I get an unusual request like burning contour vector lines onto GeoTiff images. It's a good thing the open source software GDAL has a gdal_rasterize utility to do the job. Here is an illustrated example of burning vector lines onto a raster image.
Input vector contour lines
Input raster GeoTiff file


  1. Open up a Windows Command Prompt.
  2. Type in the following command, (assuming the GDAL installation bin folder is in the system path).

    C:\> gdal_rasterize -b 1 -b 2 -b 3 -burn 255 -burn 0 -burn 0 -l contour contour.shp lub_tile1.tif

    Note 1: -burn 255 -burn 0 -burn 0 means burn the RGB color values (255, 0, 0).
    Note 2: -b 1 -b 2 -b 3 means to use the three bands of R, G, and B.
    Note 3: this utility will overwrite the input raster file, so make sure there is a backup copy of the file.


    The contour.shp vector lines are burned onto the GeoTiff file lub_tile1.tif.

Thanks for the post. I had to expand the layers of my tiff to hold the three color band layers like below:

[root@mysrv01 /]# gdal_translate -ot Byte -expand rgb /root/wfs2tiff/wmstiff.tif /root/wfs2tiff/wmsnew.tif

Then it worked perfectly for me. Maybe this will help someone else.

To get this working, I had to expand the color layers from 1 layer to 3 layers like so:

[root@mysrv01 /]# gdal_translate -ot Byte -expand rgb /somewhere/wmstiff.tif /somewhere/wmsnew.tif

Then it worked perfectly. Maybe this will help someone else.

Can you control the output contour line widths in any way?

Thank you for posting this. I was able to overlay lines from a shapefile on top of a geotiff image, but the lines are very thin. Is there another option I could specify to increase the line width output?
