Barberton Mines
Mining
The mining industry in South Africa contributes R350 billion to the economy annually, with an estimated R35 trillion of resources left to mine. Mining companies in Africa and across the globe are continually reviewing their ways of working and best practices for mining safely, efficiently, and sustainably. Research and development play a big role in these changes, with early adopters of new technologies benefitting the most.
Barberton Mines has been operational for 130 years and is located in Mpumalanga, South Africa. Consisting of several mines, including Fairview, Sheba, and New Consort, they produce ± 80,000 oz of gold annually. In recent years, Barberton has evaluated new technologies to make its mining processes fast, safe, and cost-effective.
One of the ways in which Barberton Mines investigated new technologies, was by finding ways to improve their survey workflows. They adopted static-based LiDAR solutions to produce accurate 3D models and became one of the first users of handheld SLAM solutions in 2014.
While static-based scanners are highly accurate, the survey team at Barberton Mines needed a quick and versatile solution for the variety of mining methods employed on the different mines and ore-bodies. The goal was simple; to accurately and safely capture data daily for ongoing analysis of the mining production. In addition, they needed a solution that could easily handle the rugged terrain and environment that mines are so often known for.
Barberton Mines chose to reassess their underground mapping technology to improve the speed and accuracy of their survey operations and increase productivity in the mines.
Barberton Mines was the first mine in Sub-Saharan Africa to use GeoSLAM technology when they purchased a ZEB1 in 2014. The results and continued success on the mine prompted them to invest in 4 ZEB Revo’s in 2019, which are still in use today.
The ZEB Revo is lightweight and accurate, making it the perfect tool for surveying. The survey team can complete scans of the mines in half the time, and the process is repeatable. These capabilities have contributed to Barberton Mines streamlining their workflows, long-term cost savings, and greater returns on investment.
The scanner’s ease-of-use only requires one person on-site to capture data. Furthermore, it doesn’t require professional training to use the equipment so operators can capture data in parts of the mine that surveyors cannot access for safety reasons. This casts a virtual eye on areas of the mine previously unseen by the surveyors and creates an opportunity to review old tunnels.
Finally, the lack of extensive training required to learn how to operate the scanner benefits new employees and the mine in general. It takes less than an hour to learn how to use the equipment and to process the final point cloud data, allowing surveyors to spend more time assessing final deliverables and finding ways to improve efficiencies in the mining process.
GeoSLAMs scanners have exceeded our expectations and have helped to achieve our goals where other mapping methods could not.”
– Thys Smith, Chief Surveyor at Barberton Mines
Having originally invested in handheld scanners for underground mapping, Barberton Mines have since adopted the technology for other applications, further increasing their return on investment. The scanners are now operating across three key aspects of Barberton’s mining process.
The original and most common use for scanning is Production Progress Mapping. Barberton completes daily scans of the mines, bringing the data back for regular analysis of production progress mapping.
The scanned areas are approximately 300 m3 and using GeoSLAM technology, they can scan large areas in about 10-15 minutes. In addition, because the scanners are handheld, production at the mine isn’t compromised by having to stop miners from doing their jobs while scanning is in process.
Using the ZEBs, surveyors no longer need to be underground for extended periods, unlike previous methods. They begin their scans in a safe area, proceed to the mining faces, and finish back in the safe area while capturing the data needed – a completely repeatable and efficient process.
Barberton Mines has 5-6 stockpiles that make up 4000 cubic tons of material. They frequently measure the volume of these stockpiles, to ensure they have accurate and up-to-date information on their resources.
Simply walking around the stockpiles with a scanner and importing the data into 3rd party software, provides the survey team with all the information they need to produce required reports.
One example of where scanning has improved health and safety is the mapping of transport shafts. To comply with safety regulations, surveyors frequently scan the shafts to look for rock movement or deformation that might require further investigation.
They found that scanning tunnels from the chairlift with a handheld scanner was quicker than previously used conventional methods, like Terrestrial Laser Scanning (TLS) or by hand. Handheld scanners only require the operator to ride the chairlift down- and back up again, without interfering with production.
The scanners are frequently used in these applications and their robust nature means they have never needed repair or maintenance.
Fast, efficient, and accurate data capture from GeoSLAMs handheld LiDAR scanners have proven to be a huge benefit for Barberton Mines. The repeatability of the scans has provided a great return on investment and the durability has meant that despite being used in challenging environments, the scanners have endured. The increased speed of data capture has led to safer work practices for the surveyors, and the walk-and-scan method has resulted in no disruption to the daily work of the mines.
With the scanner’s versatility, the survey team is still finding new applications where the technology can be utilised in the mining environment.
It is paramount for us to understand our client’s needs, especially in the ever-changing environment of mining. GeoSLAM provided the ultimate mapping solution that best addressed those needs, resulting in improved accuracy and overall productivity.”

Surveying
The Kansas Adjutant General’s Department coordinates resources for local, state, and federal use. They also develop internal use documents for the military, including surveying building interiors to create up-to-date and accurate floorplans for military members within Kansas.
They have about 35 sites throughout the state, with some locations 100s of miles away from the headquarters. Further, the Adjutant General’s Department manages approximately 250 buildings state-wide, totaling around 2 million sq. ft. of interior space. These factors have led to some difficulties in keeping up with projects, and any changes to the buildings and layouts.
The team found that when remodelling buildings, they were having issues getting as-builts completed in time. As-builts are documents that are used to compare a building’s design plan versus its final measurements. They also provide accurate blueprints of the building, and the surrounding land, as actually constructed at the end of the project.
Being able to have one person go out to capture all of the data and have the most current floorplans, along with the accuracy of the scanners is a gamechanger
To tackle these issues, the team decided to adopt LiDAR laser scanning technology to aid them in their projects and found GeoSLAM’s ZEB Revo to be the best option. By acquiring GeoSLAM’s technology, the Kansas Adjutant General’s Departments’ goal was to scan over half of their 2 million sq. ft. of interior space every year.
The ZEB Revo is handheld, accurate and fast, providing the team with a perfect tool. In addition, the simplicity and ease of use means only one team member needs to travel to a site, when necessary. Previous methods of data capture were not as quick or accurate. The ZEB Revo data capture leads to a faster return on projects, higher levels of accuracy, and a high return on investment.
By using the ZEB Revo, the Kansas Adjutant General’s Department have updated over 1 million sq. ft. of interior space, achieving their overall goal, with just one technician visiting half of the sites per year. The speed of capture of the ZEB means that the average time it takes the team to carry out a scan is just 20 minutes. By collecting accurate measurements, they can now regularly update their GIS database, which provides up to date floorplans throughout the state.
Data from the ZEB Revo is also used to create ‘X-Ray’ views of their properties for future plans and layouts.
Recently, they have expanded their use of handheld LiDAR technology by acquiring a ZEB Horizon, which they use for a variety of reasons. The increased range and data capture points make the ZEB Horizon a great option for large exterior scanning. This is important to the Adjutant General’s Department as they cover land of up to 50 acres.
The Kansas Adjutant General’s Department also have tanks that contain hazardous material which they need to track carefully. Using the ZEB Horizon, they scan exterior environmental factors to figure out contour lines within their complex. This helps them work out where any spillages of hazardous material would be, should one occur.
With the ZEB Horizon, the team also carry out exterior scans for asset management. Due to the scanners ease-of-use, one engineer can attach it to a truck and drive around their complex. This enables Kansas Adjutant General’s Department to scan their entire site and keep on top of their buildings and resources.
The team are also looking to expand this by attaching the ZEB Horizon to a UAV in the future.
The ZEB Horizon’s time saving, and accurate scans have proven to be a cost-effective method of data capture. For example, scans of underground empty oil storage tanks showed that the Kansas Adjutant General’s Department had been over estimating the tanks collection capacity, leading to an adjustment of the servicing contract.
Since The Kansas Adjutant General’s Department acquired GeoSLAM’s technology four years ago, they have carried out approximately 2000 scans, and this number continues to rise.
Further, the contractors and architects that create as-builts are now using The Kansas Adjutant General’s Department to quality check their work for accuracy. Using GeoSLAM laser scanners, they help find errors in specifications and relay that information to the contractors.
With the help of Seiler Geospatial Division, Kansas Adjutant General’s Department have been able to significantly improve their workflow. To find out more about Seiler, click here.

Residential & commercial properties
Real Estate
Real Estate is a fast-moving and highly competitive market. Companies are reliant on good customer relationships based on trust. They realise the importance of providing accurate measurements and specifications of the properties they are advertising. Buildings incorrectly measured could be under or overvalued, which could result in complaints, invalidate a sale, or damage their reputation.
This is particularly pertinent in the Netherlands, as they have placed a high level of importance on delivering accurate floorplans when advertising a property. In fact, a new regulation was introduced in 2010 after properties in Amsterdam were sold at a higher cost, after being overvalued due to incorrect floorplan measurements. The regulation, BBMI, requires businesses advertising properties to provide accurate floorplans or face potentially heavy fines.
This required businesses to think differently about how they could quickly and accurately assess the properties they were advertising.
Rotterdam based media and marketing company, ZIEN24, realised they needed to modernise how they measure properties in light of the regulations. ZIEN24 produces content and digital floorplans for estate agents, covering all types of residential and commercial properties.
The company began measuring properties using laser rangefinders, which were not only time-consuming but also not cost-effective. The company received complaints when properties were not measured within the limits of the regulation, and the team had to occasionally return to properties to re-measure them. In addition, ZIEN24 was sending both photographers and surveyors to properties, which was not cost-effective or ideal for their clients.
Having worked with point clouds previously, ZIEN24s co-owner, Boy Van Houten, thought that they could be the solution for accuracy. However, they needed a setup that was quick and effective, so static-based systems were not an option. After researching different scanner options, they decided to try GeoSLAM’s ZEB Revo RT with the ZEB Pano accessory.
The ZEB Revo RT is highly accurate, fast, and easy to use. As it requires minimal training, ZIEN24 taught their photographers to scan properties when they’re on location taking marketing photos. This negated the need for a surveyor, saving ZIEN24 money which could be passed on to their clients. The scanners accuracy largely removes the risk of human error, and ZIEN24 have not received any complaints since starting to use GeoSLAM scanners back in 2019.
The addition of the ZEB Pano allows them to take informative 360 degree panoramic photography, at a much quicker pace, during a scan. The ZEB Pano stores the exact location of each panoramic image within the scan, enabling more accurate and less intrusive property surveys. This is vital for ZIEN24, as the popularity of virtual house tours increases within the real estate industry.
The GeoSLAM scanner not only gives us confidence in the end product but gives our clients peace of mind knowing that our fully-automated measurements are highly accurate.
As the scanner captures in real-time, the photographers can easily ensure that they are capturing every room, as they walk around. Furthermore, the speed of capture, 200m2 in 15 minutes, means that more properties can be assigned to photographers per day. The data is then processed in their offices in China, and accurate floorplan reports are typically turned around within 24 hours.
The ZEB Revo RT has also helped them to expand into other markets, and they now offer scanning services to support BIM models.

Handheld laser scanners can determine accurate stockpile volume and tonnage measurements without the need for GPS. Walk and scan, or attach the scanner to a drone, pole, or vehicle for remote monitoring of hazardous environments. GeoSLAM’s Volumes software automates data processing to turn your scan data into actionable graphical and numerical data for real-time decision making to effectively monitor and manage your stockpiles.
Key takeaways:
Handheld laser scanning has become a crucial tool for many businesses who need to collect geospatial data. Compared to the more traditional methods, handheld laser scanning is considerably more efficient and makes it much easier to navigate through difficult spaces such as underground or narrow passages. GeoSLAM handheld LiDAR mapping solutions use next generation SLAM technology to simultaneously localize and map a space up to 10 times faster than traditional methods.
If you’re new to handheld laser scanning or think your company could benefit from this technology, then this webinar is for you.
Key takeaways:
Surveying buildings is difficult and accessing hard to reach areas, like dropped ceiling or raised floors, without disrupting business can be seemingly impossible. In this blog we’ll discuss how SLAM and LiDAR technology has made scanning behind dropped ceilings a simple process.
Known control points are captured during a scan and automatically compared and matched to the associated coordinates during the processing stage in Connect. A rigid and/or a non-rigid adjustment can be made to the dataset and an accuracy report is exported, highlighting how successful the transformation was. Users can now view and manipulate the processing parameters to ensure a more accurate match between points.
Align multiple scans using a combination of manual and automatic processes. This workflow can be performed on two or more scans in the same project. Users have a choice to export the aligned scans separately or as a single merged point cloud.
Common data capture scenarios, such as UAV, outdoor, indoor, linear, and vehicle, have been characterised in Connect and data processing pre-sets for each environment have been defined. These can be selected at the beginning of the data processing stage allowing this process to be highly simplified.
Both methods match the scan data from a ZEB Locate system with the GPS data collected from the antenna to georeference the point cloud. When a scan starts and ends in the same place, this is classed as “closed loop”. “Open loop” is when the start and end position of a scan are in different locations. Standard SLAM practices apply to both methods of data collection.
Open Loop SLAM for the ZEB Locate is available on request – let’s talk about it.
Common static points are captured during several scans meaning that these datasets can be automatically aligned. A single point cloud is then exported as if the data was captured in a single scan.
Horizontal and vertical slices can be taken from any location within the point cloud. Horizontal floor slices can also be automatically taken at a given height above the floor as defined in the processing stage.
Mostly used in the construction industry, multiple point clouds can be compared and any areas that have changed are automatically highlighted. Point clouds can also be compared with CAD models – for instance to track progress on a construction site – and PDF reports can be generated to present this information.
Some SLAM software algorithms have been made available as open-source on the internet, but they are purely algorithms and not a product that you can take and use off-the-shelf. SLAM is most successful when it is tightly coupled and designed with specific hardware in mind. A generic SLAM cannot perform as well as one that has been specifically designed for a purpose.
Visual SLAM is closer to the way humans navigate the world, which is why it’s popular with robotic navigation. But in the same vein, vSLAM will have the same image-capture challenges as humans do, for example not being able to look into direct sunlight, or not having enough contrast between the objects picked up in the image. These can be overcome indoors, however, you may need to map a forest, tunnel or urban canyon. While SLAM technologies don’t rely on remote data (meaning you can scan areas where there is no GPS), you do need to ensure the SLAM technology you chose operate well inside, outside, in daylight and darkness.
Mapping a property is time-critical. Ideally, you want to make a single visit and gather sufficient data to create a highly accurate 3D model. Ensure the software you choose transforms 3D point cloud data into actionable information in real-time. This allows you to view and interrogate your data whilst still in the field, and make any adjustments, or collect missed data, then and there.
If you’re trying to map an enclosed environment (e.g. tunnel, mine) or a complex, difficult-to-access space such as a heritage building with tight stairwells and uneven floors, you need to use fully-mobile, adaptable technology. Wheel-based systems, often used with the vSLAM camera, will struggle with access. Handheld devices or LiDAR scanners that can be attached to a drone or pole and still deliver accurate results in a rugged environment are best for navigating hazardous spaces.
While vSLAM is able to provide a qualitative high-level map and sense of the surrounding features, if you’re needing survey-quality accuracy and rich-feature tracking at a local level, you’ll need to consider LiDAR. Cameras require a high-frame-rate and high processing to reconcile data sources and a potential error in visual SLAM is reprojection error, which is the difference between the perceived location of each setpoint
and the actual setpoint.
In order to deliver the depth required for high-quality data, a number of depth-sensing cameras are needed with a strong field of view. In most cases, this isn’t possible, especially as cameras with high processing capabilities typically require larger batteries which weigh down airborne scanners, or limit the time of flight. LiDAR is both faster and more accurate than vSLAM, and can deliver detailed point clouds without expensive (and timely) camera processing.
