Virtual Geosciences

For Geoscientists, the laboratory is everywhere. Fundamental information about the formation of the rocks beneath our feet, the evolution of the landscape and evidence for ancient human activities are collected by observation in the field. Recent technological advances in digital imagery and the development of affordable and easy-to-use remote airborne vehicles (DRONES) has also opened a new chapter in field studies for geoscientists.

The School of Geosciences at the University of Aberdeen is a world-leader in the adoption and application of digital technology, combining the latest virtual tools and resources with our unrivalled field study locations on our doorstep here in Scotland and overseas.

Virtual Outcrops

V3 Geo has been developed by Aberdeen geoscientists and is a bespoke public repository and viewer for 3D virtual geoscience models, with a focus on virtual geological outcrops. V3Geo provides a selection of outcrops from localities around the world. The long-term goal is to have high-quality representations of all the world's significant geological sites.

As well as being a key research tool to enable observation of difficult-to-reach locations, it is also a very powerful educational tool for geoscientists at all levels of study. Current students are utilizing virtual outcrops from around the UK to learn key field skills that they will be able to apply to real filed study later in their careers.

Geospatial Technolgies

We have been using a number of different tools and resources in the MSc Geographical Information Sytems degree programme over the last 25 years for online mapping/webGIS, virtual fieldtrips, and geovisualisation.

For example, students create an online mapping/webGIS portal for the Knock Farm Project designed to demonstrate the role of geospatial technologies for smart farm management. This project involves the use of satellite data for land-use/land-cover mapping; creation of a geodatabase; development of a web-mapping portal; and the use of UAV monitoring and mapping, and 3D models. Students also write a report, and present their work as a pPTX presentation, and produce an A0 poster.

Others work involves gathering stereo RGB aerial photography and videography to study coastal areas, processing the aerial imagery (softcopy photogrammetry, and Structure from Motion (SfM)), to create orthomosaics, DTMs and DSMs (Digital Terrain Model/Surface) and finally generating fly-throughs using the topography or with aerial imagery draped over the DTM.

Electron Microscopy

The Aberdeen Centre for Electron Microscopy, Analysis and Characterisation (ACEMAC) provides a range of high tech facilities for industry, researchers and students, including a high-resolution Field Emission Scanning Electron Microscope (FESEM). This electron microscope uses electrons instead of light to scan everything from rocks and metal to fungi and archaeological artefacts, magnifying them up to a million times. Live scans can be transmitted remotely to lecture theatres or students' own devices, helping to bring undergraduate and postgraduate students into active research labs.
