gdal 2.1 Rasterize

Question

Is it possible to set the data type (Byte, Float32) when using gdal.Rasterize in gdal 2.1? Currently, I use gdal.Translate to convert to Byte, but this is inefficient.

Answer 1

If you are in gdal 2.1.2, use gdal.RasterizeOptions() as if you were using it on the command line:

opts_str = '-ot Byte'
rast_opts = gdal.RasterizeOptions(options=opts_str)

Answer 2

This has been fixed in GDAL 2.1.3. Previously the data type was hard-coded and not exposed in the Python bindings. See https://trac.osgeo.org/gdal/ticket/6710.
