t.create(1grass)

💖 t.create — the manual page, but make it make sense ✨

okay bestie, gather round, because today we're learning about t.create from the GRASS User's Manual and honestly? it's giving main character energy in the temporal GRASS framework 🫶

🌸 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 — allow output files to overwrite existing files. yes queen, commit the crime 🙈
• --help — print usage summary. your little cheat sheet 🎀
• --verbose — verbose module output. she's chatty and we love her for it 💬
• --quiet — quiet module output. shhh era 🤫
• --ui — force launching GUI dialog. clicky-clicky mode 🖱️

✨ Parameters

• output=name [required] — name of the output space time dataset. you literally cannot skip this one, she's mandatory 👑
• 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. give her a name bestie, she deserves one 💖
• description=string [required] — description of the new space time dataset. spill the lore 📝

💜 DESCRIPTION

so basically? t.create is used to create space time datasets of type raster (STRDS), 3D raster (STR3DS) and vector (STVDS). three flavors, all iconic 🌈

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. no cap.

the temporal type of a space time dataset can be absolute (means with a fixed date) or relative (only sequential maps) and must be set during dataset creation — along with the name and the description. like, you're deciding her whole personality at birth, no pressure 💅

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. so the metadata is dependent from the dataset type (raster, 3D raster, vector). the way that everything is connected… it's a whole ecosystem 🦋

⭐ 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"

look at her go 🥹 ate and left no crumbs.
