[Qgis-user] gridding surface

[Andreas Neumann]

Hi Marie,

Personally, I like the v.surf.rst function of GRASS which you can use
through the Processing toolbox or the Processing Graphical Modeler. It
produces rather smooth surfaces.

If you like a tin-based or IDW based interpolation you could use the
interpolation plugin which comes with QGIS (maybe you have to activate
it in the plugin manager, but it should come preinstalled with QGIS). If
you want to work with break lines you probably have to do a tin-based
interpolation as v.surf.rst does not allow for break lines.

Furthermore there are more interpolation methods builtin into SAGA and
GRASS you could try. Have a look at the GRASS and SAGA documentations.

Hope this helps to get started.

Andreas
