[GRASS-user] question about t.rast.aggregate

Hi list!

Quick question (hopefully ;P)

I need to aggregate a strds with a granularity of 1 year, but shifting the start day one month in each run, i.e.: changing the start_time to 2003-02-01, 2003-03-01, 2003-04-01 and so on…

My question is: if i recursively change start_time with the ‘where’ parameter, will the module t.rast.aggregate “aggregate” to the next february, march, april (what i’d wish) or just till the end of 2003???

Thanks much!!

Best,
Vero

Quick answer: If you specify a granularity of a year, then the start
time to perform the aggregation will always be shifted to the 1.
January of the current year and the end time the 1. January of the
next year (eg. 2002-01-01 - 2003-01-01). If you wish to aggregate a
full year but shifting one month forward then simply use a granularity
of 12 months.
