Chartered land surveryors, GeoTerra were invited by the BCRA (British Cave Research Association) to scan the cavern, so they could gain a better understanding of the geological formation. Using GeoSLAMs ZEB Horizon, GeoTerra’s goal was to map both areas accessible to the public and the narrow spaces just big enough to crawl through – a system of caves measuring 300metres long and 50metres wide.
For 40 days, 15 participants set up camp in the Lombrives cave in southwestern France with no clocks or sunlight, and zero contact to the outside world.

Jim Foster has worked in the surveying industry for over 18 years, building a well-respected company with high profile clients from all over the United States. Originally the owner of a product design company, Jim saw the opportunity to begin a new adventure in the world of surveying and has never looked back.
SLAM scanning is becoming more commonplace in the surveying industry due to the ease of use, accuracy, and versatility of the handheld devices. As the technology continues to grow, so do the benefits of handheld scanning compared to traditional means of capturing the measurements of a building. Documenting large spaces is now as simple as walking around the property to capture a pointcloud, saving both time and money for surveyors and their clients.

Canadian 3D geospatial experts Smarter Spaces engaged in a partnership with the University of New Brunswick (UNB) to laser scan a tunnel in a hydroelectric dam – producing a point cloud model to be overlaid with photogrammetry.
The Grand Falls Generating Station is a hydroelectric dam built in 1931 on the Saint John River in the Canadian province of New Brunswick and is operated by the NB Power corporation. The dam’s tunnel is shut down every 4 years for maintenance, inspection, and future life cycle planning.
This presented Smarter Spaces with the opportunity to utilise the mobile, handheld GeoSLAM ZEB Revo to scan the tunnel – creating an accurate point cloud model. In four years’ time the process will be repeated – allowing for the first side-by-side comparisons of the tunnel’s performance to be made.
In addition to this, NB Power has started exploring whether to build a 100-megawatt generating station in Grand Falls to produce more clean energy. The corporation is carrying out environmental and geotechnical studies, site tests, and consultations with First Nations and local residents before applying for an Environmental Impact Assessment later this year.
“It was a simple case of ‘walking and scanning’ through the tunnel environment“
The tunnel is approximately 3,000 linear feet in length and, because of its unique geometry, proposed an interesting set of challenges to scan. The tunnel environment was found to contain a lot of moisture – with a small stream running through the base. The IP67-rated ZEB Revo – which began life in mining environments – is rugged enough for such environments. The tunnel was dark, visibility was low, and walking conditions were slippery and wet. Smooth-sided surfaces also cause data collection issues for mobile scanners.
To overcome the risk of data slippage, 4 foot-high pylons were placed every 10 feet in random locations throughout the tunnel. This has the effect of ‘breaking up’ the monotony of the smooth-sided tunnel walls, ensuring that no data slippage occurs.
The scan data was processed in GeoSLAM Hub software to filter, subsample and merge multiple data sets together. The final models and datasets were sent to the University of New Brunswick to support an engineering graduate with their thesis research.

Precision Property Measurements | Words by Greg Davis
“We were tasked with surveying a vast private house in order to generate accurate as-built construction drawings for renovation. The unique challenge was that the 20,000 sq. ft Santa Barbara residence was occupied at the time, requiring the survey to be completed quickly and in an unobtrusive manner.
PPM (Precision Property Measurements) chose the ZEB Revo over other terrestrial scanners for our residential projects because of the speed and volume of data acquisition at exactly the level of accuracy required by our clients.
In order to keep disruption to residents to a minimum, we decided to tackle the task in two swift scans over two days. The first scan consisted of data collection of the extensive ground floor and communal areas, and took around 90 minutes to complete. The private, bedroom wing was off limits on this day.
The second scan incorporated these sleeping quarters, as well as gathering plenty of overlap from the lower floors to enable the 2 scans to be merged. After just 140 minutes of scanning, the entire house had been surveyed.
“We’ve always been confident in our ability to keep our projects to the nearest inch or less. In bringing the ZEB REVO into our arsenal of tools, we’ve kept the accuracy we’ve always had, but introduced an efficiency that allows our experts to get out there and do more for our clients“
A typical residential property of this size would have usually taken around 4 days on-site for one surveyor. PPM were able to slash this time and complete the majority of the survey work in less than 2 and a half hours with the ZEB Revo.
The use of GeoSLAM Hub software for post-processing and merging of the two datasets allowed the project team to generate a complete digital twin of the complex structure. GeoSLAM’s cutting edge mobile mapping technology was able to deliver an accuracy down to the nearest inch.
