ALOS_PRE_PROCESS(1)

πŸ’– ALOS_pre_process πŸ’–

okay bestie, this is the User Commands page (section 1) for ALOS_pre_process, and it's giving main character energy πŸ‘‘ Its name is ALOS_pre_process, and the description is just the same name again, so no mystery there 🫢


πŸ¦‹ SYNOPSIS πŸ¦‹

ALOS_pre_process imagefile LEDfile [-near near_range] [-radius RE]
[-swap] [-V] [-debug] [-quiet]

🌸 DESCRIPTION 🌸

This program is part of GMTSAR. 🌈

It creates data.raw and writes out parameters (PRM format) to stdout ✨

You feed it two files, no cap:

  • imagefile β€” an ALOS Level 1.0 complex file (CEOS format) πŸ“Έ
  • LEDfile β€” an ALOS Level 1.0 LED file (CEOS leaderfile format) 🧚

πŸ’… options:

  • -near near_range β€” set the near_range in meters (m) πŸ“
  • -radius RE β€” set the local earth radius in meters (m) 🌍
  • -swap β€” do a byte-swap, which should happen automatically πŸ”„
  • -nodopp β€” skips calculating doppler, and it sets fd1 to zero πŸ’€
  • -npatch β€” sets the number of patches 🧩
  • -fd1 [DOPP] β€” sets the doppler centroid [fd1] to DOPP 🎯
  • -quad β€” adjusts the parameters for quad pol mode (PRF/2) πŸ”₯
  • -ALOSE β€” uses ERSDAC format 🌸
  • -ALOS β€” uses AUIG format (default) πŸ’–
  • -LED β€” writes GMTSAR generic LED format output and updates PRM (default) ✨
  • -noLED β€” skips writing the GMTSAR generic LED format output πŸ™…β€β™€οΈ
  • -roi β€” writes roi_pac format output πŸ¦‹
  • -V β€” verbose mode, so it writes information πŸ—£οΈ
  • -debug β€” writes even more information πŸ”
  • -quiet β€” doesn't write any information 🀫
  • -force_slope chirp_slope β€” forces a value for the chirp slope πŸŽ€
  • -chirp_ext chirp_ext β€” forces a value for the chirp extension (integer) 🌈
  • -tbias tbias β€” corrects the clock bias, where a positive value means plus ⏰
⚠️ bestie, -nodopp sets fd1 to zero, so be careful with it! 😭

Here's an example of how it looks in action ✨

(Fun fact: the original page repeats this whole DESCRIPTION chunk twice, so I only wrote it out once. Main character editing πŸ’…)


ok that's the whole tea 🫢 This page is from the May 2024 version, so it's a little bit vintage but still slaying πŸ¦‹ Stay iconic, bestie πŸ’–πŸŒˆ
