Hi all:
I'm the creator of SidescaCalculator, a small program that a few people on this forum have tried out.
Its been a couple of years since I have been working on processing routines for the Humminbird side imaging and 3D imaging files. Thanks to the hard work by Daniel Buscombe (see
https://github.com/dbuscombe-usgs/PyHum), I have been encouraged to work on my Humminbird sidescan/multibeam project again. Some of the old Linux-based processing programs which I had previously been using, such as USGS MIPS, have gone the way of the dinosaurs. Fortunately, MB-System ( a very useful open source program for processing sidescan, multibeam, and segy data) is still active and regularly updated, and can, in fact, now directly import Humminbird xtf files. New software bundles, such as OSGeo-Live have made access to Linux programs from Windows-based machines much simpler and easier. And finally, after much head-banging, I've managed to decode and bottom pick the Humminbird multibeam (3D) data. This unit (967 3D) is no longer produced by Humminbird, but if you can get your hands on one, it is the cheapest way imaginable to do shallow-water multibeam surveys!
I've put a ton of information and links up on my website (
http://www.oceanecology.ca/new/multibeam.htm; later to be posted at
http://www.oceanecology.ca/multibeam.htm), and lots of samples of processed images. Much of the old software, such as Sidescan Calculator, that I had on my site previously, I have removed as it had become obsolete.
I hope some of this can be useful to other Humminbird users.
Cheers,
Barb (Ocean Ecology)
