[Qgis-user] slope cellsize under 0,6

[Nicolas Cadieux]

Hi,

Is your original data in latitude and longitude?  If so, you will need a z factor to have a realistic output.  To see if this is a problem, save the data in a local UTM and try again. If your xy is in long/lat and z is in meters, you need a z factor.
