Hunter Geophysics is currently developing the iOnTheSky aurora-monitoring camera network. Each camera in the network automatically takes a photograph every five minutes and allows Aurora Australis photographers to see what the Aurora Australis, light pollution, and weather conditions are like at any given moment.

There are currently five cameras installed throughout Tasmania (although one was offline for maintenance on the 31st August). We eventually hope to install dozens of cameras around the world. The footage from these cameras will be made available to the general public via iPhone and Android apps, which will hopefully be released in late 2017.

The below video shows the camera footage from the four operational cameras from 10am 31st August 2017 to 10am 1st September 2017 (from 00:00 to 23:55 on the 31st August 2017, UTC).

The four cameras are situated in Barrington (north Tasmania), Campbell Town (mid-northeast Tasmania), Bothwell (central Tasmania), and Ranelagh (southwest of Hobart, southern Tasmania). The fifth camera (which was offline that day) is based in Abels Bay (slightly further southeast from Ranelagh).




Using identical filenames in GPR-SLICE

Some GPR manufacturers produce radargram files with identical filenames across different projects or survey grids. Some users like to process multiple projects or survey grids in the one GPR-SLICE project. This means there will be conflicts due to identical filenames. This video explains how to get around this problem.

Introduction to GPR-SLICE

This video goes for 2.5hrs and should be the first thing ANY new GPR-SLICE user watches. It introduces almost everything you need to know in order to get started with GPR-SLICE.

This video assumes you are using either GPS or robotic total station navigation for your GPR data. If you aren’t using these methods, please consult the user manual (available via your user Dropbox folder; the first few minutes of the below video shows where to find the user manual), or contact us for face-to-face training via Skype (which is included in the price of your GPR-SLICE licence).

After watching this video, we strongly recommend you check out the following tutorial videos:

  1. Radargram display and interpretation in GPR-SLICE.
  2. Project management in GPR-SLICE. This will explain how to switch between projects in GPR-SLICE.
  3. Horizon detection and mapping in GPR-SLICE (this is useful for those doing GPR surveys to map any soil, rock, or road/concrete layers).
  4. Hyperbola detection in GPR-SLICE (this requires the BridgeDeck module for GPR-SLICE and allows semi-automatic detection of hyperbolic reflectors in radargrams, which is useful for those doing ground-penetrating radar surveys on concrete slabs in order to map re-enforcing bars (“reo”)).

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).
