I'm trying to find PostGIS Raster functions supports the Inverse Distance Weighted interpolation method (IDW) and Kriging interpolation method. I'm especially trying to generate a temperature map from a geometry table with point locations in PostGIS.

Can someone please point me in the right direction?

    Take a look at ST_InvDistWeight4ma (I've never used it, so someone might need to elaborate) – Mike T Mar 4 '16 at 4:45
  • You will need to use that function in conjunction with ST_MapAlgebra. – John Powell Mar 4 '16 at 12:23
