Hello,

currently it is possible to do an analysis of steepest increase/decrease of a
time-series manually using r.series:

ts1, ts2, ts3, ts4, ts5, ts6

r.series input=ts1,ts2,ts3 output=ts123 method=slope
r.series input=ts2,ts3,ts4 output=ts234 method=slope
...
r.series input=ts4,ts5,ts6 output=ts456 method=slope

then

r.series input=ts123,ts234,...,ts456 output=ts_increase method=raster_max

but it becomes quite laborious if the time-series holds many steps.

It would be great to have an option method=increase/decrease with the option
how many time-steps should be analysed for slope (ts1,ts2,ts3 or
ts1,ts2,ts3,ts4,ts5).

regards, Martin
