💖 r.in.srtm 💖

okay bestie, welcome to the r.in.srtm page from the GRASS User's Manual ✨ this lil cutie is a raster module and it's about to import some SRTM HGT files into a raster map, no cap 🏔️

✨ KEYWORDS ✨

raster, import, SRTM 🛰️

🌸 SYNOPSIS 🌸

r.in.srtm
r.in.srtm --help
r.in.srtm [-1] input=name  [output=name]   [--overwrite]  [--help]
[--verbose]  [--quiet]  [--ui]

🎀 Flags:

  • -1 — the input is a 1-arcsec tile (and if you don't say that, it assumes 3-arcsec, which is the default 💅)
  • --overwrite — lets the output files overwrite files that already exist, so like, be aware 👀
  • --help — prints the usage summary, the "help me bestie" button
  • --verbose — verbose module output, it will yap 🗣️
  • --quiet — quiet module output, it will not yap 🤫
  • --ui — forces the GUI dialog to launch

🦋 Parameters:

  • input=name [required] — the name of your SRTM input tile (that's the file without the .hgt.zip extension, ok don't include it)
  • output=name — the name for your output raster map (defaults to: the input tile name, so it just reuses it ✨)

💜 DESCRIPTION 💜

so r.in.srtm imports SRTM HGT files into GRASS, periodt. 🗺️ both SRTM Version 1 and the improved Version 2 data sets are available for download from NASA at these sites:

and the gap-filled SRTM Version 3 data can be downloaded from USGS over here:

🔥 NOTES 🔥

SRTM tiles are 1 degree by 1 degree in size, iconic square behaviour. 📐 the SRTM filename contains the coordinates, and those coords refer to the center of the lower left pixel — so for example N51E010 means the lower left cell center is at 10E, 51N, iykyk.

to figure out a tile name, you can easily visualize a grid with d.grid:

d.grid size=1

and if you wanna import TOPEX/SRTM30 PLUS data instead? that's a whole different vibe, use r.in.bin 💫
