[GRASS-dev] spline interpolation over time series

[Margherita Di Leo]

Hi all!

I need to analyse several MODIS in time, and calculate the temporal spline
interpolation (for each pixel), then pick the values (date and value) on
the spline function corresponding to percentiles 25, 50, 75, maximum,
minimum and average.
I know that with r.series I can get max, min and average, but I can't
currently apply a spline interpolation. I'd like to know if in the temporal
modules there's something to do that or I should hack the r.series in order
to add the spline interpolation. I found this
http://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html#spline-interpolation
that
I can probably use for the scope.

Thanks for any hint
