Presenting at The UK National Earth Observation Conference 2018

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.

 

Emlid Reach RS Training

Today I provided an informal training session for interested Keele GGE staff, students and postgraduates, on the use of the Emlid Reach RS GNSS antennas for survey grade georeferencing. The training focused on setup, configuration, survey techniques, potential pitfalls and suggested uses.

I have been using the Emlids since early February 2018 when they were purchased by the department, throughout there use they have proven to be an excellent and cheap alternative to the more familiar GNSS systems offered by the likes of Leica, Trimble and Topcon.

First Guest Lecture

Giving PresentationToday I gave my first guest lecture at Keele University. The lecture provided an overview of the many ways in which geophysical data can be georeferenced, and the associated accuracies for each method. This included GNSS, Total Stations, Structure from Motion (SfM), Lidar, through to mobile mapping systems.

I felt that the lecture was well recived with a good level of student interaction via mentimeter.

Skeiðarárjökull Baseline Survey Complete

I have safely returned from a successful eight day field trip to Skeiðarárjökull, Iceland to carry out the baseline survey alongside my wife and willing field assistant  Sam Davenward. Despite the exceptionally changeable March weather we managed to install permanent control at six localities, carry out UAV flights for Structure from Motion (SfM) photogrammetry and acquire EM-31 conductivity data for each site.

It was great to physically experience the environment I have been learning about for my Literature review and to be able to appreciate the scale of the Ice buried in the subsurface at Skeiðarárjökull.

Thanks to my field assistant (Sam Davenward), supervisors (Dr Richard Waller and Dr Alex Nobajas) and the Skaftafell Rangers for there help and support in relation to this initial fieldtrip, and I look forward to the next season.

Important Note

It is forbidden to fly drones within Skaftafel National Park without permission from the park rangers. A research permit was granted prior to fieldwork being conducted.
