NAME

t.topology - Lists temporal topology of a space time dataset.

KEYWORDS

temporal, topology, time

SYNOPSIS

t.topology
t.topology --help
t.topology [-ms] input=name [type=name] [where=sql_query] [--help] [--verbose] [--quiet] [--ui]

Flags:

-m: Print temporal topological relationships and exit
-s: Print spatio-temporal topological relationships and exit
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=name [required]: Name of the input space time dataset
type=name: Type of the input space time dataset
Options: 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’

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
