💖 t.vect.list — GRASS GIS User's Manual 💖

okay bestie, gather round, because this is the t.vect.list page from the GRASS GIS User's Manual and it's genuinely one of the most useful little gremlins in the temporal toolkit 🦋

✨ 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 [-u] input=name  [order=string[,string,...]]
[columns=string[,string,...]]   [where=sql_query]   [method=string]
[separator=character]   [output=name]   [--overwrite]  [--help]
[--verbose]  [--quiet]  [--ui]

🎀 Flags 🎀

  • -u — Suppress printing of column names. like, the header row just does not show up. rude but efficient 💅
  • --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=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

🌈 DESCRIPTION 🌈

The t.vect.list module provides the same functionality as t.rast.list, the only difference is the vector map layer metadata. so yeah, same energy, different dataset. twin modules, no cap 👑

🍓 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
shoreline_1970_1988@shoreline|shoreline_1970_1988|None|shoreline|1970|1988|18|121
None|None|None|None|1988|1997|9|139
shoreline_1997@shoreline|shoreline_1997|None|shoreline|1997|None|None|148
None|None|None|None|1997|1998|1|148
shoreline_1998@shoreline|shoreline_1998|None|shoreline|1998|None|None|149
None|None|None|None|1998|2003|5|149
shoreline_2003@shoreline|shoreline_2003|None|shoreline|2003|None|None|154
None|None|None|None|2003|2004|1|154
shoreline_2004@shoreline|shoreline_2004|None|shoreline|2004|None|None|155
None|None|None|None|2004|2009|5|155
shoreline_2009@shoreline|shoreline_2009|None|shoreline|2009|None|None|160

okay that's the whole page bestie, you ate that 🫶

and for the cute sign-off: this whole thing lives in the GRASS GIS 8.4.2 Reference Manual, it's © 2003-2025 GRASS Development Team, and the page itself is stamped GRASS 8.4.2 down at the bottom, t.vect.list(1) era. periodt 💅✨
