Day 1

Measuring the potential impact of offshore mining on coastal instability through integrated time-series laser scanning and photography

by Neil Slatcher, Roberto Vargas , Chris Cox and Liene Starka, 3D Laser Mapping

Measurement of unstable slopes in actively mined coastal areas is critical to assess the associated hazards and potential impacts upon local infrastructure. Here, we present preliminary results of an automated approach that integrates airborne time-series online-waveform lidar data and image-based terrain feature tracking to quantify coastal slope instability in an area of active offshore mining. We demonstrate that automatic terrain classification using lidar data can be used to exclude areas unsuitable for image-based surface feature tracking from the analysis, enabling the measurement of maximum surface displacement rates. Surface-to-surface comparison of lidar-derived terrain models was also used to determine maximum surface profile changes.

 

Reality capture: from point cloud to design to visualisation

by Shuaib Yunos, Baker Baynes

In an ever-expanding world, breakthroughs are made constantly. Every day, the bar is set higher and higher as technology is at its pinnacle. From an infrastructure standpoint, the world is moving to a higher form of urbanisation, resulting in super cities and project development.  Crucial infrastructure and processes need to be prioritised and streamlined in a sequential, effective manner such as the development of roads for access, structures for shelter and services, planning for future growth, geotechnical data analysis, geospatial elements, etc. These tasks need to be accomplished in a workflow that integrates practicality, efficiency and technology to achieve the desired objective in the most optimised, economical and time efficient manner. This paper will look at Autodesk Recap and how its implementation can increase productivity and proficiency.

 

3D laser scanning and DTH hole surveys in stope design and quality monitoring

by Kalumba Bwale, Lubambe Copper Mine Zambia

Since the first functional laser being built and tested in 1960, various applications for the laser have been developed over the years. The spatial coherence of lasers makes them ideal measuring tools in situations where measurements need to be taken in inaccessible points and areas. This property gave rise to cavity monitoring systems (CMS) and laser scanners. Technology, that enables huge volumes of spatial data to be collected within a remarkably short period of time.

 

Open source GIS software: supporting a geospatial intelligence approach to counter copper cable conductor theft  Best Paper Award

by Ryno Goosen, Suritec Geospatial

This paper will discuss the development of a predominantly open source geospatial information system to support a geospatial intelligence capability in countering copper cable conductor theft (cable theft). The solution supports the collection, processing, storage, analysis and visualisation of sensor and human derived information in a geographical area of operations. Ultimately, it aims to improve decision making regarding the pro-active deployment of costly and finite resources.

 

GIS-based monitoring system to enhance safety and stability

by Hamid Ashraf, Frederick Cawood and Sarfraz Ali, University of the Witwatersrand

This article illustrates the real-time ground behaviour monitoring system for the Sterkfontein Caves. A geospatial subsidence hazard model of the Sterkfontein Caves used a GIS approach to identify potentially hazardous areas from the point of view of ground movement and possible collapse. The aim of that study is to ensure public safety in a concentrated area frequently visited by the public and is part of a programme to identify appropriate digital technologies for mining.

Uncovering where to provide optimised services

by Laurette Coetzee, AfriGIS

We are living in the era of communication – and we expect super-fast communication.  Therefore, we need super-fast networks to allow us to communicate at anytime, anywhere.

 

Technologies in the geotech and infrastructure spectrums

by Shuaib Yunos,, Baker Baynes

The world population is increasing at a substantial rate, this results in a greater need for infrastructure development, producing infrastructure in the most viable, fastest ways possible. Crucial infrastructure and processes need to be prioritised and streamlined in a sequential, effective manner such as the development of roads for access, structures for shelter and services, planning for future growth, geotechnical data analysis, geospatial elements, etc. These tasks need to be accomplished in a workflow that integrates practicality, efficiency and technology to achieve the desired objective in the most optimised, economical and time efficient manner. This paper will look at some of the technologies available that assist in relation to the above, promoting productivity and proficiency.
