Hello Martin,
If your DTM raster is in *.bil or *.asc format then you can use LAStools'
> las2iso or blast2iso from the LiDAR Processing toolbox.

Ok. :)
But, my DTM is a simple GeoTIFF. :(
Do you know if gdal permits to create curves from a GeoTIFF DTM,
clipped by a rectangle BBOX ?
Perhaps, I need to clip my DTM, before, with the "gdal_translate" and
then send the result to "gdal_contour" ...
There is no way to do it in a single shot ? :)
Who knows ?
Thank you
Roberto
