GPR-SLICE tutorial video: automated horizon/layer detection and mapping

This tutorial explains how to detect buried horizons and map the depth to sub-surface layers in GPR-SLICE. This is useful for mapping concrete slab thickness and depth to bedrock or potentiometric surfaces (e.g. the water table).

GPR-SLICE tutorial video: automated hyperbola detection using the BridgeDeck module

This video explains how to automate the detection and mapping of hyperbolic reflectors within GPR datasets, and how to map the variation in signal amplitudes for radar traces that fall within the detected hyperbolae. This is particularly useful for mapping rebar in concrete and how to map corrosion of rebar across a site – all remotely, all using ground-penetrating radar.

Creswick Cemetery – report

Just a quick blog post this time, but it’s accompanied by a lengthy survey report, which – I am sure – more than makes up for this post’s brevity.

Before I go on: Happy Easter to everyone. I hope you all stay safe and enjoy the long weekend (or holiday, for those lucky enough to get more than the weekend off!).

I have uploaded a copy of the report I wrote for our geophysical survey at the Creswick Cemetery. The survey, of course, sought to detect any unmarked graves in the Cemetery. Ground-penetrating radar (GPR), magnetic gradiometry, electrical resistivity, frequency domain electromagnetics (EM or FDEM) – specifically, ground electrical conductivity – and aerial photograph analyses were thrown at this site and have revealed a great deal of information not only regarding the unmarked graves present, but also of the former Sexton’s cottage and natural soil processes, as well as old geological features such as palaeochannels.

This was a very interesting survey and has yielded some fantastic results. We have also learned a great deal regarding the applicability of various geophysical techniques to the detection of specific types of buried features.

The full report can be downloaded from our website. Note that it is a thirty megabyte file, so it may take some time to download.


Best wishes to all for Easter.


Update: fixed report download link – sorry about that!
