Hi,<br>
<br>
I read your thread on using gdal.RasterizeLayer() in Python to rasterize vector polygons by attribute. I have the same problem as you did. Can you tell me how you resolved it please?<br>
<br>
My code is almost identical to yours and my key line is:<br>
err = gdal.RasterizeLayer( target_ds, [1], vector_lyr,<br>
options = ["ATTRIBUTE=id", "ALL_TOUCHED=TRUE"] )<br>
<br>
The rasterize process seems to ignore my options. Like you, I get an output raster with all no-data values set to 255. I get a zero error value.<br>
<br>
Your insights would be very welcome. Many thanks in advance.<br>
<br>
Regards<br>
<br>
Jonathan<br>
