r.series.interp
Interpolates raster maps located (temporal or spatial) in between input raster maps at specific sampling positions.
r.series.interp [input=name [,name,...]] [datapos=float [,float,...]] [infile=name] [output=name [,name,...]] [samplingpos=float [,float,...]] [outfile=name] [method=string] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]
Example:
r.series.interp
grass.script.run_command("r.series.interp", input=None, datapos=None, infile=None, output=None, samplingpos=None, outfile=None, method="linear", overwrite=False, verbose=False, quiet=False, superquiet=False)

DESCRIPTION
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.
EXAMPLES
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.
