✨ NAME ✨

lonlathei2ascii</purgle> — create 3 column ASCII files from the binary doris output

yes bestie that's the whole name section, it's short and it knows it 💅

🌸 DESCRIPTION 🌸

lonlathei2ascii v1.0 Doris software, bert kampes, (c)1999-2003

🌈 SYNOPSIS 🌈

lonlathei2ascii longitude_file latitude_file height_file output_file

So here's the tea ☕: this csh-script creates an 3 column ASCII file with "lon lat hei" from the binary doris output (matrices) after step geocode. It filters out invalid data, indicated with "-999" by Doris. Not me gatekeeping bad pixels, we simply do not associate with them 🙈

The output file can be used further with GMT to create a grd file. The format of the 3 input files are matrices in real4 float format, all of the same size. They describe the irregular geocoded position of the pixels in the interferogram, and the corresponding heights. fr fr, all three gotta match up or it's a vibe check fail 😭

The steps taken are within this script:

1. Create 3 temporary ASCII files with all data in a single large column using cpxfiddle program;
2. Create a single 3 column ASCII file (lon lat hei) using "paste";
3. remove -999 invalid data using "grep"
4. Tidy up, remove temp files.

These steps may take a while. Obviously staying in binary format would be better. Yeah bestie, we know, we know 💀

This script is intented to work on all platforms, and to be straightforward and understandable, rather than ingenious.

not me pointing out that they wrote "intented" — we love a legend who ships anyway, no cap 💅

🦋 DEPENDENCIES 🦋

• cpxfiddle program, part of Doris distribution.
• grep utility, standard UNIX
• paste utility, standard UNIX

Note that lambda=longitude; phi=latitude — iykyk 🧚

okay so real talk — the original page literally prints this entire block again right after itself. Not a glitch, that's just how it is. I'm not about to skip it, so here it is, the encore, the remix, the double feature 💀✨
