Mine works in Northern England - Industrial heritage becomes geotourism Nenthead Mines Commendium is often requested to assist with mine works filming and conservation projects but rarely both at the same time. We were invited by veteran Geologist Andy Freem and his wife Antonia. We were asked to scan elements of the Nenthead Mines, located near Alston in Cumbria. The project was to provide complementary 3D and drone footage and data to be included in Andy’s latest film production. Capturing the landscape The film opens with aerial video captured by our licenced drone operator. It shows the whole mine workings above ground. This video was processed into a 3D model using Pix4D software. Inside the mine Underground, using 3D laser (LiDAR) we scanned two sections of the Smallcleugh Mine, which is part of the overall Nenthead mine complex. Smallcleugh is in the centre of a 50+km complex of mine levels and underground workings, and it contains evidence of the lives and techniques of the lead miners working there for over 200 years. Whimsey Chamber The first scanning target was a ‘Whimsey Chamber’, where horses were brought underground to walk around in circles, providing power to lift and lower items in the adjacent shaft. It is quite remarkable how much of lift feature remains. The 3D models illustrate the mine in fine detail and inform the viewer as to its construction in ways that pure video cannot. The Flats The second 3D scan illustrates the ‘flats. Flats are areas where miners hacked and blasted out lead ore from valuable veins. It illustrates the incredible handwork, and stonework used to create arches and build stacks, to support the mine roof. Nenthead Mine Works Film The Nenthead Mine video may be viewed on YouTube and offers a rich and fascinating illustration of the mine. The whole area around Nenthead still has many former mine works and invokes a timeless picture of life in Victorian England. Whilst this mine is easily and freely visited, if you are not experienced in the underground activities we recommend hiring a guide or taking a guided tour. Need more information?

Scanning the 2nd largest cave chamber in Europe. Commendium have deployed their 3D mapping systems in several caves around the world and we were invited back by the Karst Institute in Postojna, Slovenia to complete a 3D survey of the Skocjanske Cave system. As a part of a UNESCO World Heritage Site, the data was required for geological studies and an appreciation of the state of the cave for monitoring purposes. On one wintery morning in January we set off via the ferry to Skocjanske in Slovenia which boasts the world’s finest portfolio of amazing karst caves. Karst caves are known for their delicate ecosystem and exhilarating topography and the region around Skocjan is seen as the home of Karst geology. The brief was to monitor the condition of the cave and take measurements using highly accurate 3D LiDAR, then build digital models of the caves. After a calm ferry journey and a long drive, we reached Slovenia and were pleased to see our hosts, who are now becoming like family. After a good sleep, we gathered the team and set off excitedly. With the Reigl Scanner, batteries, photography kit, caving gear, and the drone all weighing in excess of 30kg, we started on the 2-hour walk to the Martel Chamber. John Nelmes was particularly excited to be on his first trip to Slovenia with his drone, but not so excited when he saw the cave entrance and the 70m sheer drop. We finally reached the chamber via 1.5 km of narrow paths, hacked into the sides of caves by original explorers followed by 4 rope river crossings and lots of traversing on ledges. During the expedition, we found that the Martel chamber is, in fact, the second largest cave chamber in Europe, and 11th largest in the world. Skocjanske Cave System Flood A few days after our trip, a huge thaw saw the river rise from 2 cubic metres of water per second to a peak of 290, flooding the chamber where we had been working to a depth of 90m. There was no danger, this cave is the most monitored cave in the world, there was no risk of being marooned. The results will take a year or so to process but already three scientific papers are underway. The survey is also being used to assess the feasibility of establishing other tourist paths within the cave. Overall, Commendium's Slovenia trip to the Skocjanske Cave System was very successful and…
Sonar surveying the floor of a flooded quarry Usually, you will find us below ground scanning or climbing through to the next cavern with a huge amount of scanning equipment, not carrying out SONAR surveying from the back of a boat in winter. This morning we set out to map the floor basin of Capernwray, a former quarry, now flooded and used as a dive centre. The reason for this early start and rubber dingy journey is to test out a new sonar rig to ascertain if it’s going to deliver the results we need for upcoming bathymetric surveys of several tropical rivers. The rig loaded and ready for use today is the StarFish 452F; for those of you who are technically inclined, the starfish is is a high-frequency side-imagining, sonar device. The starfish is an unusual design with hydrodynamic three fins, it differs greatly from the common cylindrical torpedo shape side scan of many sonars. [caption id="attachment_210" align="aligncenter" width="200"] The Starfish 452F[/caption] With the StarFish - 452F loaded safely and attached to a rope of 10m, we set off across the quarry lake to test the range and resolution capabilities of the imaging device, which promised us wide range imaging of 100m per channel, which is 200m total swathe coverage. The surveying process The sonar surveying took us approximately 20 minutes, with a distance of 0.5 km. With the data safely gathered we rushed back with the data to see what this compressed high-intensity radar pulsing bit of kit could deliver, and would it be enough? Safely back in the office, we launched the data and saw some very convincing and highly detailed scans produced. Overall, we were indeed happy with the Starfish side scanner, which had picked up several artifacts in the lake including a sunken plane. The detailing of the plane wasn’t high resolution, but the floor of the lake and side facings were captured in full quality, which is exactly what we need from the Starfish. We are now working on programming methods to turn this data into a 3D image of the lake floor. View the video below to find out a little more about the process:
Commendium CEO, Richard Walters, has been back in China surveying the world’s largest cave chambers in 3D. Using the latest LiDAR techniques he and his team have been revealing the true nature of some recently discovered huge caves in Guangxi and Guizhou provinces. His team resurveyed the world’s largest cave chamber, The Miao Room and found it to be even larger than previously believed. At almost 11 million cubic metres it is about ten times the size of Wembley stadium. Giant Sinkhole Of more note, was the survey of a seemingly small hole, called Maoqidong, situated about 10m from an important road through the mountains near a town called Leye. That there was a huge cave below was clear, as warm damp air condenses as it leaves the hole leaving a signature column of steam rising from the ground. The survey confirmed it was an immense 260m to the floor of the cave. A further 200m down a steep slope to an underground river showed, for the first time, the chamber to be an immense 6.2 million cubic metres in volume. Alarmingly, the road was found to be a mere 4m from this underground cavity. Richard produced a detailed report for the local authorities to highlight the road’s precarious position above the invisible void below. This giant sinkhole could have caused major problems for local infrastructure. Surveying Technique The mapping technique involved 3D laser scanning from selected stations around the cave and on the surface near entrances. Then on return to the base camp, stitching all these scans together using specialist software. Commendium used its own methods and tools to reduce errant points and generate clean point clouds from which geo-located 3D models were produced. To find out more about how we do this, please take a look at our LiDAR scanning services or Contact us.
There are many hidden gems throughout the UK. Possibly one of the strangest is Gilmerton Cove in Edinburgh. No-one really knows how or why these strange tunnels were chipped out of the rock below Edinburgh’s busy streets, but there are many amusing stories to add to the mystery.Gilmerton Cove commissioned Commendium to visit the tunnels and create a full-colour digital model of the workings for their records, for heritage, conservation and architectural reasons. This included visual representations to enable people, for whom a trip down a deep cold mine would not be attractive, to appreciate the work of the Victorian miners as well as models suitable for architectural and historical studies. Glimerton Cove LiDAR Survey In a single trip, Commendium staff laser scanned the tunnels workings with state of the art LIDAR laser scanning equipment and took over 1000 photographs, from which a highly detailed, colour digital model was built.Commendium constructed a detailed digital 3D model of Gilmerton Cove and confirmed that at present the tunnels do not extend under the road, though it is clear they have in the past. The hight between the road surface and the tunnels was confirmed to be less than 0.5m, thus informing the cove of the need to consult with structural engineers to ensure safety. The format of the model was made so that it is available to Computer CGI applications, architectural packages and historical documentation. Why Commendium? We provide high quality, accurate LiDAR scanning services to help a wide range of industries visualise physical data. This data can be output in many different ways, from CAD drawings, to meshed models. Gilmerton Cove was a great example of what we can do, but we have plenty of other examples to show you.

Commendium are currently partnering with Wardell Armstrong in providing detailed archaeological recording using drones for certain archaeological sites along the route of the proposed HS2 High-Speed railway. We have developed a process that allows us to capture not only video and photography for each of the sites but also elevation maps, orthomosaic maps, and 3D photogrammetric models. The data we are collecting is invaluable in determining if further investigation is needed in the areas but also allow for archaeologists to find new and hidden features. On a recent survey, we were asked to assist the BBC in filming for a new documentary using our drone. This was because the permissions to fly over the sites is so tightly restricted that we were the only company with authority to perform this. As these are active working sites, Commendiums surveyors have successfully applied for CSCS cards and qualifications to become authorised for construction site work. This has opened up a new avenue of work for Commendium and we are currently testing how to use photogrammetry within the construction industry. Our photogrammetric and LiDAR services are able to quantify the mass of excavations, provide detailed location data for constructions and accurately measure buildings, rivers, ditches and more. Aligned to the drone technology, we are able to carry out this work much quicker than traditional methods and much more accurately. More archaeological recording using drones surveying for the HS2 project is coming in and we expect our involvement to continue over the next few years. The project does present some challenges for us, but our team of specialist are able to overcome this by providing a completely bespoke service. In this project, the flight plans are generally pre-determined, but room is left for changes when on site. An example of this is a recent site that had a number of red kites within the boundaries of the surveying area. An ecologist was on hand to check the nests and to advise our drone operator of any potential issues. In fact, during one of our flights, we can see one of the red kites fly within about 20 feet, but the bird of prey completely disregards our drone.

Whitehaven, is a bustling town in West Cumbria, overlooking the Irish sea. Like many ‘seaside’ destinations in the UK, Whitehaven has seen a drop in popularity with the influx of cheap flight holiday packages. However, with a rejuvenated sea-front, and an expansion of industrial business in the area, is resulting in a revitalised town full of life and fun. Commendium was asked to LiDAR scan the 'old Whitehaven seafront'. This involves scanning the area to collect all the geographic details and building information. Having scanned the front, we were asked to produce a 3D model in a format which would be familiar to architects. Commendium constructed a detailed digital 3D model based on the point cloud data from the LiDAR scan. The data was gathered via 60 separate scanning stations strategically plotted around the seafront area. All the expected challenges surfaced during the scanning, lots of wind, rain, water spray, curious bystanders, seagulls, and car movements. However, despite the wild weather, we created a perfect point cloud and from this data, the architect’s model was built using SketchUp software. Building the model in SketchUp aided the architects, who are already familiar with SketchUp software. We followed this up by building a model in Revit which was then used for architectural processes and procedures. This was highly accurate and saved time and money. They were able to view the model and used the information to assess and guide their decisions. A planning proposal for the area has subsequently been submitted and considered by the authorities. We offer a number of services that can cut costs and save time for architects, including highly accurate LiDAR scanning, photogrammetric modelling of large areas, data processing and more.

Yorkshire here we go again, off to Swaledale to scan a fascinating disused lead mine called Sir Frances level. The NYDNP commissioned Commendium to visit St Francis Level to create a full colour digital model of the mine workings for their heritage records. This included visual representations, to enable people, for whom a trip down a deep cold mine would not be attractive, to appreciate the work of the Victorian miners. In addition, the created models are suitable for architectural and historic studies. Over a series of 5 trips to the mine, Commendium staff laser scanned the mine workings with state-of-the-art LiDAR laser scanning equipment and took over 5000 photographs, from which a highly detailed, 3D colour digital model was built. There’s lead in those hills Scattered throughout the North of England are hundreds of abandoned mine workings, leftovers from the Victorian Period, when the Industrial Revolution, transformed Britain into a modern technology driven country that needed raw materials from anywhere they could be found to satisfy the demand. The deliverable outputs The following products were delivered to the client: Commendium constructed a detailed digital 3D model of the workings in St Francis Level. From this model a short film was made which can be viewed on YouTube and is currently being shown at the Dales Museum in Hawes. The models have been archived and have been used for Historical Studies. In addition, they have been called upon to drive an application for further funds to preserve these precious items. The format of the model was developed to be viewed over Computer CGI applications, architectural packages, and historical documentation. Nice clip on BBC Most recently Commendium has been asked to contribute to a BBC film featuring St Francis Level mine. Paul Rose interviews Richard, with our graphics and 3D models featuring in the clip. See Richard with ‘Paul Rose on the Yorkshire Dales’ here [About 10 minutes in] https://www.bbc.co.uk/iplayer/episode/m0004513/the-yorkshire-dales-series-1-2-swaledale Lead, silver, coal and more besides was extracted from these small private mines working throughout the local hills, which employed thousands. The relics of this period may still be found. Some mines, when you are armed with appropriate skills and equipment to enter, reveal a wealth of industrial heritage. Water powered Lift The St Francis Level contains a unique water powered lift, which was used to raise and lower miners to various levels. The lift is one example of industrial heritage at…
These ruins lie in the unlikely setting on the coast of Lancashire overlooking the Morecambe Bay. Quite the most beautiful spot despite proximity to the decommissioning nuclear power station at Heysham point. Commendium was commissioned to build a 3D model of The Chapel for heritage and conservational purposes, as a record so that its condition could be reviewed over the years. A series of approximately 300 photos was taken around the site and places in to Agisoft Photogrammetric software from where the model was built The model provides a reference – a point in time as to the state of the buildings from where its condition will be reassessed in due time.
Commendium recently scanned the worlds largest cave to help understand these underworlds better. Caves contain unique geological and meteorological records. Increasingly, the sediments they hold and the strata from which they are formed are being using to study and understand the Earth in ever more detail. They hold particularly valuable insights as they have been undisturbed erosion, be that due to human activity or natural meteorological processes. However, caves are dark, and so those parts that are beyond reach of the lights that speleologists can carry, have not been studied. Until now.Commendium has been part of a worldwide project to LIDAR scan the great natural chambers of the world in order to create a data set for further study. To date fifteen have been completed. We visited and documents caves in The USA, Mexico, Belize, China, Oman, Malaysia, France and Spain. It involved full scale speleological expeditions to enter and explore these places. Largest Caves in the World Commendium constructed a detailed digital 3D model of the all the caves in a variety of formats. The data sets are being used to date events in the cave development and also to date deposits that are being used to reveal climate change records over the last million years. This is corroborated with data from other sources, such as Ice Caps Cores, to improve the worldwide understanding of climate change. Cave records will allow climate change studies to reach back almost ten times further than any other source. National Geographic funded one element of this project, from which Commendium helped to build an array of 3D interpretations to help their readers understand these wonderful places. A film of the worlds largest cave was made by Commendium and can be viewed on Youtube. What we can do Commendium are specialist in scanning subterranean worlds. We go to places no-one else dares to gather the data needed for a variety of diffeent projects.
