v.kernel's "Standard deviation in map units" field is not clear
|Reported by:||arencambre||Owned by:|
Discussing with Markus Metz, it's apparent that v.kernel's Standard deviation in map units field is unclear and has different meanings depending on the kernel function used. E.g., the actual kernel radius is currently a function of the SD and the selected kernel function.
USers should be just asked for the radius in map units. The SD would be adjusted as necessary depending on the function.
It may be OK to retain an SD field for advanced cases, but it should not be on the Required tab of the v.kernel UI.
