Dear colleagues I would like to the advantage of the t.* modules for detrending a strd.
In the strd I have earth observation data irregularly sampled (2 or 3 times per month), in the period November-February, for 7 years. They are not equally spaced (i.e gaps have different duration)
A simple t.rast.series analysis (opion=slope,offset) highlights that probably there is a descending trend when considering the maps ordered by id.
I would like to fit a proper time depending fitting curve for each pixel and then subtract the function from the real data.
any hints on how I can do this task exploiting the GRASS GIS modules or some simple bash/python scripting?
thank you Ivan _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
