This is very interesting -- I think I may have an immediate application for
these modules...

Best to you in 2012 and thank you for your development activities!

> Dear all,
> just for your information. I have added a new option to r.series to
> specify a weighting factor to each map in a series. Weighting is
> needed to aggregate overlapping/containing interval time series
> correctly in case of average and sum operations. The new temporal
> modules tr.aggregate and tr.aggregate.ds need this option.
> Furthermore i have added a new module (r.series.interpol) to
> interpolate raster map series located temporal or spatial in between
> existing raster maps. This module is still under development and
> implements currently only simple linear interpolation in a normalized
> interval. I plan to implement step-wise linear interpolation[1] and
> natural cubic spline interpolation[2].
> Because of the large amount of files related to the unit and
> regression tests located in the modules directory, we should use a
> dedicated one.  Hence, i will move successively all files related to
> testing into new directories named "test" located in the module
> directories.
> Best regards and happy new year 2012
