t.topology
Lists temporal topology of a space time dataset.
t.topology [-ms] input=name [type=name] [where=sql_query] [--verbose] [--quiet] [--qq] [--ui]
Example:
t.topology input=name
grass.script.run_command("t.topology", input, type="strds", where=None, flags=None, verbose=False, quiet=False, superquiet=False)
Example:
gs.run_command("t.topology", input="name")
Parameters
input=name [required]
Name of the input space time dataset
type=name
Type of the input space time dataset
Allowed values: strds, stvds, str3ds
Default: strds
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'
-m
Print temporal topological relationships and exit
-s
Print spatio-temporal topological relationships and exit

DESCRIPTION
The module t.topology lists temporal relations of the maps in a space time dataset.
EXAMPLE
In order to obtain information about space time dataset topology, run:
t.topology tempmean_monthly@climate_2009_2012
