r.series.interp - Interpolates raster maps located (temporal or spatial) in between input raster maps at

       Sören Gebbert

r.series.interp interpolates new raster maps located temporal or spatial in between existing raster maps.
       The  interpolation is performed at specific sampling positions. The sampling position for each output map
       must be specified, as well as the data position of the input maps.  The following  interpolation  methods
       are supported.

           •   linear: Linear interpolation. At least two input maps and data positions are required.

       Interpolate linear three new maps at 3 sampling positions in the interval (0.0;1.0)
       First prepare the input maps:
       g.region s=0 n=80 w=0 e=120 b=0 t=50 res=10 res3=10 -p3
       r.mapcalc expr="prec_1 = 100"
       r.mapcalc expr="prec_5 = 500"

       Interpolate
       r.series.interp --v input=prec_1,prec_5 datapos=0.0,1.0 \
                         output=prec_2,prec_3,prec_4 samplingpos=0.25,0.5,0.75 \
                         method=linear

       Interpolate using the file option.  First prepare the input file:
       echo "prec_2|0.25
       prec_3|0.5
       prec_4|0.75" >> outfile.txt

       Interpolate:
       r.series.interp --v input=prec_1,prec_5 datapos=0.0,1.0 file=outfile.txt method=linear
       The resulting maps will have the values 200, 300 and 400.
