PROGRAM:

NAME

t.vect.list - Lists registered maps of a space time vector dataset.

KEYWORDS

temporal, map management, vector, list, time

SYNOPSIS

t.vect.list
t.vect.list --help
t.vect.list [-s] input=name [order=string[,string,...]] [columns=string[,string,...]]
[where=sql_query] [method=string] [separator=character] [--help] [--verbose]
[--quiet] [--ui]

Flags:
-s
Suppress printing of column names

--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 vector dataset

order=string[,string,...]
Sort the space time dataset by category
Options: id, name, layer, creator, mapset, temporal_type, creation_time, start_time,
end_time, north, south, west, east, points, lines, boundaries, centroids, faces,
kernels, primitives, nodes, areas, islands, holes, volumes
Default: start_time

columns=string[,string,...]
Columns to be printed to stdout
Options: id, name, layer, creator, mapset, temporal_type, creation_time, start_time,
end_time, north, south, west, east, points, lines, boundaries, centroids, faces,
kernels, primitives, nodes, areas, islands, holes, volumes
Default: name,layer,mapset,start_time,end_time

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’

method=string
Method used for data listing
Options: cols, comma, delta, deltagaps, gran
Default: cols

separator=character
Field separator character between the output columns
Special characters: pipe, comma, space, tab, newline
Default: pipe

DESCRIPTION

This module provides the same functionality as t.rast.list, the only difference is the
vector map layer metadata.

EXAMPLE

Default query
This example show a relative space time vector dataset with the first three maps with a
range of years, instead the last five are valid only for one year:
t.vect.list shoreline@shoreline
name|layer|mapset|start_time|end_time
shoreline_1849_1873|None|shoreline|1849|1873
shoreline_1925_1946|None|shoreline|1925|1946
shoreline_1970_1988|None|shoreline|1970|1988
shoreline_1997|None|shoreline|1997|None
shoreline_1998|None|shoreline|1998|None
shoreline_2003|None|shoreline|2003|None
shoreline_2004|None|shoreline|2004|None
shoreline_2009|None|shoreline|2009|None

Using method option
Method option is able to show vector in different way. By default cols value is used, the
value deltagaps will print the delta between maps and also the gaps if they exist (like in
this example).
t.vect.list method=deltagaps input=shoreline
id|name|layer|mapset|start_time|end_time|interval_length|distance_from_begin
shoreline_1849_1873@shoreline|shoreline_1849_1873|None|shoreline|1849|1873|24|0
None|None|None|None|1873|1925|52|24
shoreline_1925_1946@shoreline|shoreline_1925_1946|None|shoreline|1925|1946|21|76
None|None|None|None|1946|1970|24|97
