💖 v.what.strds 💖

okay bestie, welcome to v.what.strds, a page from the GRASS GIS User's Manual. she's a lil module that uploads space time raster dataset values at positions of vector points to the table. yes that's a mouthful, no i will not be shortening it, that's literally what she does. ✨

🦋 KEYWORDS 🦋

vector, temporal, sampling, position, querying, attribute table, time

✨ SYNOPSIS ✨

v.what.strds
v.what.strds --help
v.what.strds [-u] input=name strds=name[,name,...]  [output=name]
[where=sql_query]   [t_where=sql_query]   [--overwrite]  [--help]
[--verbose]  [--quiet]  [--ui]

🎀 Flags:

  • -u — Update attribute table of input vector map. So instead of making a whole new vector map, she just updates the attribute table with the value(s). lowkey the glow-up-in-place option. 💅
  • --overwrite — Allow output files to overwrite existing files. she will simply replace what's there, no questions asked. 👑
  • --help — Print usage summary. your bestie when you're lost. 🥺
  • --verbose — Verbose module output. she tells you everything. no cap.
  • --quiet — Quiet module output. she says nothing. mysterious. main character energy. 🤫
  • --ui — Force launching GUI dialog. pop-up era. 🌈

🌸 Parameters:

  • input=name [required] — Name of input vector map. Or data source for direct OGR access.
  • strds=name[,name,...] [required] — Name of the input space time raster datasets. yes, plural, you can hand her a whole list, comma-separated, she's built different. 💖
  • output=name — Name for output vector map.
  • where=sql_query — WHERE conditions of SQL statement without 'where' keyword. Example: income < 1000 and population >= 10000
  • t_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 💜

okay so. v.what.strds retrieves raster values from a given space-time raster datasets (STRDS) using a point vector map. that's it. that's the whole thing. she samples the STRDS at your points and writes the values into the table. the way that she just does that. 🦋

🍓 NOTES 🍓

TBD.

(i'm not even kidding, that's what it says. the authors left this one as TBD and honestly? relatable. we'll find out together bestie 😭)

🧚 EXAMPLES 🧚

v.what.strds input=mypoints strds=mystrds output=newvector

look at her go. points in, STRDS in, new vector out. ate and left no crumbs. ✨
