💖 t.create — the GRASS GIS bestie manual, but make it cute 💖

okay so you wanna make a space time dataset? say less. this is t.create(1) from the GRASS GIS User's Manual and I'm gonna walk you through it like we're texting at 2am 🦋

✨ NAME ✨

t.create — Creates a space time dataset. yes that's the whole job. she creates. she's an icon. 👑

🌸 KEYWORDS 🌸

temporal, map management, create, time ⏰

🎀 SYNOPSIS 🎀

t.create
t.create --help
t.create output=name  [type=name]   [temporaltype=name]
semantictype=string title=string description=string  [--overwrite]
[--help]  [--verbose]  [--quiet]  [--ui]

🫶 Flags:

  • --overwrite — lets output files overwrite existing files. she's bold. she's not asking permission. 💅
  • --help — prints the usage summary, aka the "help me bestie" button 🙈
  • --verbose — verbose module output, she's telling you EVERYTHING
  • --quiet — quiet module output, she's giving mysterious and silent 🤫
  • --ui — forces launching the GUI dialog, for when you want the pretty buttons ✨

🍓 Parameters:

  • output=name [required] — name of the output space time dataset. this is literally required, don't skip it 🚨
  • type=name — type of the output space time dataset
    • Options: strds, stvds, str3ds
    • Default: strds
  • temporaltype=name — the temporal type of the space time dataset
    • Options: absolute, relative
    • Default: absolute
  • semantictype=string [required] — semantic type of the space time dataset
    • Options: min, max, sum, mean
    • Default: mean
  • title=string [required] — title of the new space time dataset 📛
  • description=string [required] — description of the new space time dataset 📝

💜 DESCRIPTION 💜

so t.create is the girl who creates space time datasets of type raster (STRDS), 3D raster (STR3DS) and vector (STVDS). no cap.

Space time datasets represent spatio-temporal fields in the temporal GRASS framework. they're literally designed to collect any amount of time stamped maps with time intervals and time instances. the temporal type of a space time dataset can be absolute (means with a fixed date) or relative (only sequential maps), and bestie — it must be set during dataset creation along with the name and the description. no setting it later, that ship has sailed 🚢

Time stamped maps can be registered in and unregistered from space time datasets. the spatio-temporal extent as well as the metadata of a space time dataset is derived from its registered maps. hence the metadata is dependent from the dataset type (raster, 3D raster, vector). iykyk 🌈

⭐ EXAMPLE ⭐

🌸 Absolute STRDS dataset

Create a raster space time datasets:

t.create type=strds temporaltype=absolute \
         output=precipitation_monthly \
         title="Monthly precipitation" \
         description="Dataset with monthly precipitation"

🦋 Relative STVDS dataset

Create a vector space time datasets:

t.create type=stvds temporaltype=relative \
         output=precipitation_monthly_30y \
         title="Monthly precipitation 30 years" \
         description="Test dataset with monthly average \
         precipitation in the last 30 year"
