PHASE2TOPO(1)

💖 PHASE2TOPO 💖

okay bestie, welcome to phase2topo — that's the phase2topo manual page, from section 1 of the manual, and yes she is serving exactly what her name says 🫶

---

✨ NAME ✨

phase2topo — literally just phase2topo. that's it. that's the name. iconic minimalism 💅

---

🌸 SYNOPSIS 🌸

phase2topo master.PRM topo_in.grd res_phase.grd topo_out.grd

four files, in this order, no vibes-based reordering allowed, bestie 😭

---

🦋 DESCRIPTION 🦋

so this little legend is part of GMTSAR 🌈 (you know, the whole SAR crew). and what does she do? she computes residual topography. periodt.

phase2topo [GMTSAR] - Compute residual topography

here's the cast of characters you're handing her, one by one 🎀

• master.PRM — the master PRM files, used for mapping. she needs these to know where stuff is, no cap.
• topo_in.grd — name of the input topography, and it has to be in the radar co-ordinates of the master. 🛰️

and then the rest of the fam, tucked right in there:

• res_phase.grd — name of the input phase per unit baseline.
• topo_out.grd — name of the output corrected topography, also in the radar co-ordinates of the master.

⚠️ note this, bestie, for real: the residual phase should be scaled by the perpendicular baseline (see bperp). don't skip that step, she will simply not do it for you 🙈

and just to say it again, because the page itself says it again (she said what she said, twice 💀):

phase2topo [GMTSAR] - Compute residual topography

🍓 Usage 🍓

Usage: phase2topo master.PRM topo_in.grd res_phase.grd topo_out.grd

• master.PRM — master PRM files used for mapping ✨
• topo_in.grd — name of input topography in the radar co-ordinates of the master 💜
• res_phase.grd — name of input phase per unit baseline 💜
• topo_out.grd — name of output corrected topography in the radar co-ordinates of the master 💜

⚠️ and once more, with feeling: the residual phase should be scaled by the perpendicular baseline (see bperp). that part is not optional, bestie, it's giving mandatory 🔥

and that's the whole page, bestie — every last crumb, nothing dropped 💖

this came to you from the phase2topo page itself, dated May 2024 — the source and the date, right at the bottom where the footer lives 🎀 go compute that residual topography, you absolute main character 👑
