[gdal-dev] How can I generate an empty geotiff based on the extent of the shape file?

[Dane Springmeyer]

Hi John,

If you can't use use gdal_translate to flatten an existing raster you  
can try creating one from scratch using one of the supported language  
bindings.

The python bindings work particularly well for this since you can hook  
into numpy.

See: http://trac.osgeo.org/gdal/wiki/FAQRaster#HowcanIcreateablankrasterbasedonavectorfilesextentsforusewithgdal_rasterize

Cheers,

Dane
