[Qgis-developer] How to generate DTM iso-curves of QGis canvas ?

[Martin Isenburg]

Hello Roberto,

If your DTM raster is in *.bil or *.asc format then you can use LAStools'
las2iso or blast2iso from the LiDAR Processing toolbox. All LAStools have
"native" support for the BIL and ASC formats and convert these rasters
on-the-fly into a point-cloud on a grid.

Regards,

Martin @rapidlasso
