Description

Good afternoon. I always use v.surf.rst in Qgis 2.16 and 2.18 to interpolate points using a raster as a mask, but it is not working in QGIS 3.2.0. I got an error message in red (see attached file). I use the default parameters.

[processing] split v.surf.rst algorithm into two (fix #19472)

This algorithm cannot output cross-validation results and topographic
parameters simultaneously, hence two tools needed. Thanks to Pedro Venâncio
for finding this and proposing a fix.

There is a problem with paths to GRASS executables:

"C:\PROGRA~1\QGIS" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

In the meantime use QGIS LTR (2.18), is safer at this stage (for Processing tools).

it works OK here in 3.4.3 on Ubuntu (but not using a temp point layer).

no, is not working, my mistake.

#13 Updated by Pedro Venâncio almost 6 years ago

The problem with v.surf.rst in QGIS 3.x.x is because it is trying to output the cross-validation result and the topographic parameters at the same time, and this is not possible.

So, the approach needs to be the same as in QGIS 2.x.x, by separating v.surf.rst in two different processing modules (v.surf.rst and v.surf.rst.cvdev).

I attach the description files with this approach. I can make a pull request with this update, but if someone can do it quicker (Nyall? Giovanni?), I appreciate that, because at this moment I don't have access to my dev machine. And this needs to be backported to QGIS 3.4.x.

Thanks!
