What tools in the Sextante toolbox in QGIS 1.8 can be used for interpolation (kriging and spline)?

I have looked at every single one and could not figure it out.

Considered using SAGA as SEXTANTE provider?

  • Does that require me to download a new program? I have not heard of SAGA. – T.J. Jun 17 '13 at 20:12

    Yes it does, but it is fairly simple and i really recommend it as it adds over 239 new geoalgorithms, which are really powerful. Download the zip from here (saga-gis.org/en/index.html ), unzip it somewhere on your drive and specify the directory in your SEXTANTE options (providers -> SAGA). You can use all the SAGA tools inside of QGIS, so no need to learn another GIS program (which is very good and fast by the way) – Curlew Jun 17 '13 at 20:18
  • Thank you. A classmate also advised that I can go into the options and then click active for SAGA and it brings up all the tools. Is this different than downloading it. – T.J. Jun 17 '13 at 20:21
