cannot enter useful values to r.param.scale curvature tolerance in wxPython GUI
|Reported by:||cmbarton||Owned by:||martinl|
The s_tol (slope tolerance) and c_tol (curvature tolerance) arguments are not well documented for r.param.scale, but turn out to be of great importance in achieving useful results of terrain classification. s_tol values are in degrees but c_tol is in unitless curvature values. Useful values range between 0.0000 and 0.0006 according to the documentation.
For some reason, the GUI only allows values to 3 decimal places (0.000) in the s_tol and c_tol fields. This means that it is impossible to enter any values between 0.0000 and 0.0010 even though these are exactly the values that need to be entered. Of course you can enter these from the command line, but this bug cripples use of this module for many users.
I don't know where the decimal place is specified in the code--in the interface description in the C code, or somewhere in the wxPython interface parser code.
