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
