Gunlink Revisited

January 24th, 2025

Some years ago, I wrote a small utility to view Seamap’s Gunlink SEGD files.

As I didn’t have much data to test with, it had some limitations.
Recently, I acquired some more files that has let me take it a bit further.
It now shows other variants including the pseudo SEAL as well decoding the external header if available.

This header contains a wealth of QC information and has got me thinking about a fully fledged QC application that
will track gun performance. Whether I actually get around to writing it remains to be seen.

It is available as Nagware

Seismatters lives for another Year

November 29th, 2024

Seismatters is back, thanks to the generosity of an anonymous benefactor who paid the web hosting for another year.

Not much else has changed.

I am still looking for work, almost anywhere as a QC rep.

SMSFExplorer

October 29th, 2023

A while back I was sent some 4 component data with a request (more a demand actually) that I provide a way to
view each component separately as a contiguous data set.

It was a sort of an interesting objective and one that I had considered in the past.
The result is SMSFExplorer.
As with many of my projects, it started out as one thing and morphed into something else.
In this case it became a comprehensive Seis file header examiner and extraction utility.

Select a folder and it will provide a list of valid Seis files
Click on any of the entries and it will load the headers for viewing
Click the header you are interested in and it will show it:

Click on a trace number and the trace header you are interested in and it will show that

You can also look at the trace itself if you want

But it doesn’t stop there.
You can export a QC header listing as text, Shape File or KML file.

And of course what we originally set out to do, a SEGY file

Exporting allows for not only the export of a specific component, but a line or channel range.

So in the end we went from a useless (from the point of QC) record with mixed sensors

To a nice record only containing the Hydrophone data

The program is still a bit fragile, so I will not make it available except to specific people on request, and then only if they can show a need for it.

 

 

Domain Names For Sale

September 13th, 2023

seismatters.co.uk and beforesiam.com are available for purchase if anyone wants them.
Currently seismatters.co.uk redirects to seismatters.com

Only the domain names are for sale, they do not come with any content.

I will consider sensible offers.
Please contact me if you are interested:

https://seismatters.com/feedback.html

I also plan on shutting down seismatters.com in about a year.
I see no point in continuing to support an industry that has turned it back on me. It is an expense I can no longer afford.

Added some more interesting plots – Productivity and Team Production. They can be useful to find out who is working and when.

I am still looking for work. Any leads would be appreciated.

The big one being graphical displays of reports.
