I’ve been working on mounting the new Flir Vue Pro R to the phantom over the last few weeks. The wooden prototype worked reasonably well but was a bit off balance, the new 3D printed design flys much better and has mounting slots for the battery and for better securing of the camera and battery. I did a few tests using video, timelapse and photos but need to tinker with the settings a bit more before taking it out to Iceland.
The mount flys well, and doesn’t inhibit the use of the phantoms inbuilt camera, I’ve also worked out how to georeference the thermal images.
Things I’ll be looking into in the coming weeks include…
- Tweaking the settings
- Optimum height for acquisition
- Stitching together thermal images
Looking forward to an exciting few weeks ahead.
I’ll be heading out to Iceland again in Easter 2019 to carry out some repeat UAV surveys of my field sites, fortunately, the equipment is a little more portable this year. I’m looking forward to seeing the topography change over the last year. I’ll also be carrying out a thermal imaging survey from the drone at dawn/dusk to help identify areas of ground ice. In addition to this, I will be building on the geophysics (EM-31) collected last year, by using resistivity to collect resistivity sounds to help constrain cover and ice thickness. Depending on how the preliminary tests go next week I may also collect some 2D transects using a different configuration of the resistivity equipment. As mentioned before this fieldwork is kindly supported by the NSGG.
Some more great news, my submission (see above) to the BGA photograph competition won second prize, first prize went to an amazing photograph taken offshore retrieving equipment from between icebergs as if it were a giant hook a duck (really impressive, both the activity and the photo). The photographs were judged by the BGA committee at the Postgraduate Research in Progress Meeting in the University of Cardiff. The prize money will be put towards the next field season which will hopefully yield more photographs of geophysical surveys being carried out among the beautiful scenery of Iceland.
Thanks again to the British Geophysical Association
Following a successful funding application, the Near Surface Geophysics Group (NSGG) are funding part of my next field season in Iceland. The Field season is planned for Easter 2019. I plan to carry out repeat flights over my current sites to identify any subtle changes in topography, take resistivity readings to identify cover and ice thickness and collect thermal imaging at dawn and dusk to help identify any potential ground ice.
This is great news and I’m looking forward to the planning and execution of the fieldwork early next year.
A big thankyou to all concerned at the NSGG.
My the literature review component has been submitted today, just in time for Christmas. I’ve learnt a lot but still have a lot more to learn and I’m looking forward to getting back into processing more of my data from the previous field season and preparing for the next (Easter 2019) where I plan to carry out resistivity surveys and collect some repeat UAV surveys in SE Iceland. Thanks to my supervisor Dr Richard Waller for the support and encouragement while writing the literature review and to Dr Sam Davenward and Gethin Evans for proof reading for me.
After leaving myself two hours additional time to get to Birmingham, to account for Birmingham rush hour traffic I found myself abandoning the car in a carpark further away than planned and putting my recent running training to good use, arriving just in time to upload and present my research in the photogrammetry session at the UK National Earth Observation Conference.
I presented the results from the baseline survey I carried out earlier this year. The focus of the talk was on the 3D models and DTMs produced for sites in Iceland, and how they were constrained and process to maximise resolution so that cut and fill models may be created using future repeat surveys. There was interesting to see similar processing methods being used for monitoring blanket bogs, using lidar generated point clouds.
I also learned more about remote sensing and what data is available, unfortunately, the resolution of the satellite data is not sufficient for my buried Ice project, I will be keeping an eye on the data for large-scale changes in surface topography over my PhD using Sentinel data.
If you saw the presentation I welcome any feedback or questions, also if you were not present or wanted to review the presentation at your own pace, the slides are available in the download section of this website.
Busy day today in Leeds. I presented the results from my baseline survey in Iceland to the NSGG Postgraduate Research Symposium and was featured in a poster about geophysical survey with a mausoleum.
I was pleased with how my presentation went and if I didn’t pronounce Skeiðarárjökull right it was very close and sounded vaguely Icelandic. I received lots of good feedback and the other presentations stimulated some interesting discussion about a range of topics.
Unfortunately I missed a few of the presentations after lunch, but I did manage to squeeze in a quick meeting with George from Coptrz to discuss latest drone technologies (particularly thermal imaging and multi spectral cameras) and how they could be incorporated into my dead ice project, taking into account the need to transport the equipment by plane (LiPo batteries and planes don’t mix well).
I look forward to seeing how the other participants project a progress in the future, and would like to thank all involved for organising the event.
