Hi Nikos, the columns that you use in the where condition of temporal modules are those in the SQLite table that stores metadata about each map in the st(r)ds: min, max, start_time, end_time. AFAIK, there's no metadata for the mean, i.e. no column in the SQLite table containing that info. Here there are some examples with t.rast.list [1] using where. Maybe the error message could be improved as to specify which columns are available.
If, from the output t.rast.univar (with or without -e) you want to get those maps where LST mean is higher than 10, then you would need a different procedure. What I did eventually, was import the .txt file into R, and there, make queries with sqldf package. There's for sure other much better options that I would love to learn. hth, Vero [1] https://grasswiki.osgeo.org/wiki/Temporal_data_processing#Listing_maps_and_selections 2017-10-21 14:34 GMT+02:00 Nikos Alexandris <n...@nikosalexandris.net>: > Shouldn't the following work? > > t.rast.univar lst where="mean > 10" > .. > sqlite3.OperationalError: no such column: mean > > > 'min', 'max' and 'start_time' work. > > Where are the "columns"? > Isn't the whole of what t.rast.univar -e reports supported? > > Thank you, Nikos > > _______________________________________________ > grass-dev mailing list > grass-dev@lists.osgeo.org > https://lists.osgeo.org/mailman/listinfo/grass-dev >
