[GRASS-user] r.resamp.bspline lambda default

Hi,

I noticed that when r.resamp.bspline is invoked with the --help flag, the
default lambda parameter is reported as 0.01, but in the manual page, there is
this text:

"For seamless NULL cell interpolation, a small (lambda) value is required and
default is set to 0.005".

Is this a typo in the doc?

Yes, I would say so.
With "git blame" it is easy to track changes. It was changes from
0.005 to 0.01 in this change
https://github.com/OSGeo/grass/commit/62242c0dc8802cbe9c9b21af36e2afadff128ddf
and the needed documentation update didn't happen.

Thanks for catching this.

Fixed in
https://github.com/OSGeo/grass/commit/33d147388119b8dcc65adb9607337805841a0e49

and backported (upcoming 7.8.5).

cheers,
Markus
