Bonjour tous le monde,


I have generated a 30m and 31m contour lines for Richelieu river and lake
Champlain (using SRTM data). It fits the 30m contour provided by
Jean-Guilhem but doesn't seem to fit pretty well the flooded wetland area
provided by Pierre.


Any idea if this data can be used (usgs licence point of view)?

And if it can be usefull?

This is exact. The 40 meter contour line is not usefull for us.


Thanks Jean-Guilhem.
