Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

Mining has historically been described as a boom-and-bust industry, where fluctuations in mineral prices could result in extreme success or bankruptcy. Successful mining companies closely monitor assets/expenditures, risks, and other parameters associated with their business to best ensure their longevity. In most mineral industries, there are a few competitors that dominate the delivery of a mineral resource. As a result, technological development, along with other factors, are critical to ensure that these companies’ business remains viable and protected.

This is according to post-doctoral fellow in the Department of Geology, Dr Martin Clark.

Drone technology: better, faster, safer

He says technological development in mining generally translates to how a company can extract a resource from the ground better, faster, and safer. 

Dr Clark believes the rapid development of drone technology represents a shift in the toolbox that mining companies can employ.

“Drones can collect a great deal of data randomly over vast or small areas within hours, historically accomplished by mapping campaigns which can last months to years. Drones can also collect data in areas which are difficult and dangerous for humans to get to. These include cliff faces or rock walls that are difficult and dangerous to get close to, as well as stretches of land where dense vegetation, inaccessible terrain, and even atmospheric dangers become factors which reduce or modify the scope of exploration work,” he said. 

Expanding application of drones

Dr Clark’s work specifically focuses on expanding the applications for which drones are used. “I assess what and how good the imaging capabilities of drones are, use the imagery to generate 3-D models to drive scientific observation, and yield results which can help companies to extract resources. This initiative is called MAGIC (Multi-purpose Aerial Geological Image Classification),” he said. 



“MAGIC aims to collect geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes,” he added.

Dr Clark is not only the founder of MAGIC; he also drives multiple aspects of the initiative including education, research, and business development. 

In 2013, when he was busy with his doctorate, there was already a spark of interest in using drones to address geological questions. At that time, Dr Clark was working with remotely sensed high-resolution LiDAR imagery to better understand geological structures at the Sudbury Mining Camp in Canada. The interest became a reality in 2018, when he applied this initiative during his post-doctoral fellowship at the UFS.

Now and the future

“At present, there are no direct mining projects underway, but projects are expected to begin in 2020. Drone operation and image-analysis techniques are currently being refined for industry,” he said. 

Besides his work with drones, Dr Clark also work in the fields of structural geology, remote sensing, and geospatial data analysis.

Space-based information plays vital role in disaster-risk reduction
2017-02-28

Africa is one of the continents most affected by disasters triggered by natural hazards. The result of climate change is a reality that affects every human being, whether it is extreme heat waves, cyclones, or the devastation of drought and floods. Climate change can provoke injuries or fatalities and affects the livelihoods of people in both rural communities and urban areas. It triggers damage and losses in various sectors of development, such as housing, road infrastructure, agriculture, health, education, telecommunications, energy, and affects routine economic processes leading to economic losses.

According to Dr Dumitru Dorin Prunariu, President of the Association of Space Explorers Europe, space programmes have become an important force defining challenges of the 21st century. “Space observation is essential for climate-change monitoring,” he said.

Dr Prunariu was the keynote speaker at a two-day symposium on climate resilience and water that was hosted by the Disaster Management Training and Education Centre for Africa (DiMTEC), at the University of the Free State (UFS). He participated in the Soviet Union’s Intercosmos programme and completed an eight day-mission on board Soyuz 40 and the Salyut 6 space laboratory, where he and fellow cosmonaut Leonid Popov completed scientific experiments in the fields of astrophysics, space radiation, space technology, space medicine, and biology. He is the 103rd human being to have travelled to outer space.

The focus of Dr Prunariu’s lecture was: Space activities in support of climate change mitigation and climate resilience.

Space-based information, an extra eye that can detect a way out during disasters
“For governments to support communities affected by any disaster, precise and up-to-date information on its impacts is essential as a way to respond in a timely and effective way,” said Dr Prunariu.

Space-based information (derived using Earth observation, global navigation satellite systems, and satellite communications) can play a vital role in supporting disaster-risk reduction, response, and recovery efforts, by providing accurate and timely information to decision-makers.

“With space-based information, disaster management teams will be able to take note of recently established roads that may not appear in typical maps produced by National Geographic Institutes, but which could be used as emergency evacuation routes or as roads to deliver humanitarian assistance to those who require it in remote areas."

Space-based tools help decision-makers to improve planning
“Space-based tools and spatial data infrastructure is also crucial for policy planners and decision-makers in increasing the resilience of human settlements. Using geographic data and information collected before the occurrence of major disasters in combination with post-disaster data could yield important ideas for improved urban planning, especially in disaster-prone areas and highly-populated regions.

“In the recovery process, information on impact is used by governments to provide assistance to those affected, to plan the reconstruction process, and to restore the livelihoods of those affected,” said Dr Prunariu.

“Space observation is
essential for climate-
change monitoring.”

The symposium was attended by representatives from Liberia, Nigeria, Kenya, Ghana, Namibia, and Zimbabwe, with various international scientists from Europe imparting their expert knowledge on water and global resilience. The presence of these international experts strengthened global networks.
