t.rast3d.univar t.rast3d.univar --help t.rast3d.univar [-es] input=name [zones=name] [nprocs=integer] [output=name] [where=sql_query] [separator=character] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags

-e: Calculate extended statistics
-s: Suppress printing of column names
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters

input=nameÂ [required]: Name of the input space time raster3d dataset
zones=name: Raster map with zones to compute statistics for
Raster map with zones to compute statistics for (needs to be CELL)
nprocs=integer: Number of threads for parallel computing
0: use OpenMP default; >0: use nprocs; <0: use MAX-nprocs
Default: 0
output=name: Name for output file
where=sql_query: WHERE conditions of SQL statement without ’where’ keyword used in the temporal GIS framework
Example: start_time > ’2001-01-01 12:30:00’
separator=character: Field separator character between the output columns
Special characters: pipe, comma, space, tab, newline
Default: pipe

Description

t.rast3d.univar provides the same functionality as t.rast.univar, the only difference is the 3D raster map layer metadata. Please refer to the manual page of t.rast.univar for documentation and examples.
