gpx2dzg - visualize and convert GPS marks to GSSI's proprietary NMEA file, DZG

published: May 17, 2019, 6:48 p.m.

I discuss a piece of open-source software I wrote for use as a visualization and converter tool for converting GPS and SIR-4000 marks to GSSI's proprietary file format called DZG.

By far the most frustrating datasets I've had to deal with in the past few years are GPR projects that had no GPS input directly in the field. GSSI devices have the ability to record NMEA sentences and correlate them with mark numbers, but ...

readgssi - python visualization software for ground-penetrating radar

published: Feb. 14, 2019, 8:22 a.m.

I discuss an open-source software tool I wrote for use as an reader and preprocessing module for data from a specific brand of ground-penetrating radar (GPR) devices.

readgssi is a tool intended for use as an open-source reader and preprocessing module for subsurface data collected with Geophysical Survey Systems Incorporated (GSSI) ground-penetrating radar (GPR) devices. It has the capability to read .DZT and .DZG files, and filter, plot, and export the ...

Raspberry Shake

published: March 28, 2017, 7 p.m.

In which I discuss the coolest, relatively inexpensive new tool for geology and seismology geeks.


Shake It

No, not like that.

Those who know me know that I am obsessed with data. If you know me well, you may know that my favorite kind of data is live, autonomous, remotely sensed data. Thus you can probably see why ...

In which our house texts us to let us know if it's comfortable inside or not.


cron is a data gatherer's best friend. Pretty much every time I build something cool, there is scheduling involved. Whenever there's scheduling involved, I rely heavily on cron to do all of it for me. And why shouldn't I? As ...

Weather Underground Webcam with RaspberryPi

published: July 6, 2016, 11:23 a.m.

In which I explain how to use a RaspberryPi and a $10 USB camera to power a Weather Underground webcam service.

RaspberryPi (RPi) is an ongoing software and hardware concept project by the RaspberryPi Foundation which seeks to create user-friendly customizable development devices. (Basically really tiny computers designed to connect to all sorts of sensors and be powerful enough to run code to process data from those sensors.) Their ...
