Application of mixed and virtual reality in geoscience and engineering geology

Visual learning and efficient communication in mining and geotechnical practices is crucial, yet often challenging. With the advancement of Virtual Reality (VR) and Mixed Reality (MR) a new era of geovisualization has emerged. This thesis demonstrates the capabilities of a virtual continuum approach using varying scales of geoscience applications. An application that aids analyses of small-scale geological investigation was constructed using a 3D holographic drill core model. A virtual core logger was also developed to assist logging in the field and subsequent communication by visualizing the core in a complementary holographic environment. Enriched logging practices enhance interpretation with potential economic and safety benefits to mining and geotechnical infrastructure projects. A mine-scale model of the LKAB mine in Sweden was developed to improve communication on mining induced subsidence between geologists, engineers and the public. GPS, InSAR and micro-seismicity data were hosted in a single database, which was geovisualized through Virtual and Mixed Reality. The wide array of applications presented in this thesis illustrate the potential of Mixed and Virtual Reality and improvements gained on current conventional geological and geotechnical data collection, interpretation and communication at all scales from the micro- (e.g. thin section) to the macro- scale (e.g. mine)

Geoscience after IT: Part L. Adjusting the emerging information system to new technology

Coherent development depends on following widely used standards that respect our vast legacy of existing entries in the geoscience record. Middleware ensures that we see a coherent view from our desktops of diverse sources of information. Developments specific to managing the written word, map content, and structured data come together in shared metadata linking topics and information types

Developing digital fieldwork technologies at the British Geological Survey

Geological Surveys are faced with budget constraints and calls for efficiency gains; the effective application of digital techniques is often seen as a route to meeting these demands while increasing the value of outcrop studies and reducing the inherent subsurface uncertainty. The British Geological Survey may be the oldest national Survey in the world (established in 1835); however, developing and implementing new, innovative and efficient technologies for fieldwork is a high priority. Efficient tools for capturing, integrating, manipulating and disseminating outcrop data and information are imperative to enable geoscientists to increase their understanding of geological processes and therefore to reduce subsurface uncertainty and risk. Systems for capturing structured digital field data and for visualizing and interacting with large datasets are increasingly being utilized by geoscientists in the UK and internationally. Augmented reality and unmanned aerial vehicles are amongst the developing technologies being explored for future operational implementation. This paper describes the digital field mapping (BGS·SIGMAmobile) and visualization (GeoVisionary) systems and refers to a case study outlining their contribution to reducing uncertainty and risk in hydrocarbon exploration

Cheap, accessible, and virtual experiences as tools for immersive study: a proof of concept study

Virtual and augmented reality technology is becoming more commonly available within a plethora of environments in which we exist, including educational environments. With advances in technology, and more exposure to its capabilities, there is a greater expectations and reliance on it. However, much of the hardware (and some of the software) which makes this technology usable is expensive and inaccessible to many. This article introduces a method for capturing and providing cost-effective virtual reality experiences, used here as a tool to give students improved accessory data and context regarding geological lab samples. The method introduced utilises the Google Cardboard camera app and Google Cardboard viewers. The virtual reality environment created is a mini-immersive experience that could be provided to students, or collected by students for their own use. The article reports results from a study of 20 participants who answered a questionnaire outlining their experiences of implementing the method. They responded positively, highlighting the applicability of the method to the task, the ease of use of tool and the accessibility of technology. Image quality of the method was raised as an area for improvement.</jats:p

Digitising Svalbard’s geology: the Festningen digital outcrop model

The renowned Festningen section in the outer part of Isfjorden, western Spitsbergen, offers a c. 7 km-long nearly continuous stratigraphic section of Lower Carboniferous to Cenozoic strata, spanning nearly 300 million years of geological history. Tectonic deformation associated with the Paleogene West-Spitsbergen-Fold-and-Thrust belt tilted the strata to near-vertical, allowing easy access to the section along the shoreline. The Festningen section is a regionally important stratigraphic reference profile, and thus a key locality for any geologist visiting Svalbard. The lithology variations, dinosaur footprints, and the many fossil groups, record more than 300 million years of continental drift, climate change, and sea level variations. In addition, the Festningen section is the only natural geoscientific monument protected by law (i.e. geotope) in Svalbard. In this contribution, we present a digital outcrop model (DOM) of the Festningen section processed from 3762 drone photographs. The resulting high-resolution model offers detail down to 7.01 mm, covers an area of 0.8 km2 and can be freely accessed via the Svalbox database. Through Svalbox, we also put the Festningen model in a regional geological context by comparing it to nearby offshore seismic, exploration boreholes penetrating the same stratigraphy and publications on the deep-time paleoclimate trends recorded at Festningen
