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

output=name

Name for output file

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
