LandScope has recently taken delivery of a BlueView BV5000 3D sector scanning sonar system from Teladyne BlueView for the purposes of underwater asset survey and inspection.
Having rigorously tested the technology in several demanding underwater environments, we have been impressed with the system’s versatility and data resolution.
Integration of the BlueView system allows us to take our established 3D scanning service below the waterline, providing an unprecedented level of detail and accuracy to underwater asset owners and operators.
A structural radar survey was recently carried out over the interior and exterior faces of a 40 metre diameter concrete salt dome structure in Sheffield.
The aim of the survey was to assess the reinforcing configuration, identify any areas of voiding and deterioration, and to design a concrete coring programme.
The work will enable the client to determine the likely lifespan of the dome and any remedial work requirements.
In early 2014 LandScope was awarded a long term dam monitoring project which involved the installation of survey monumentation and associated target systems. Tasked with extending the survey to assess verticality and deformation, we deployed a configuration of laser scanning and specialist registration systems to deliver the highest possible resolution and accuracy.
Following our annual audit we are pleased to have been re-awarded the ISO9001 Quality Management System accreditation.
LandScope prides itself on maintaining a most practical management system, whilst always striving towards new and innovative data management processes with consistently high standards. We were delighted that the external auditor commended us on the excellent systems in place.
In April we highlighted we were currently engaged on a survey of the Norfolk Broads – part of a three year programme to obtain bathymetric data over much of the Broads network. Our surveying team recently returned to the area in continuation of the project, although with better weather than in April! Once again they were utilising our dedicated inshore survey launch ‘Polecat’.
The resulting data will enable the Broads Authority to design an informed and cost effective dredging campaign.
Further information on our hydrographic survey work can be found here.
We have recently upgraded our autoMAP mobile mapping system to deliver densified LiDAR data and significantly greater photographic resolution.
The Topcon IP-S2 Compact+ incorporates a Ladybug 5 camera and upgraded SICK laser scanners configured in an ‘X’ array.
The inspection and survey of bridge infrastructures brings with it many challenges, and the traditional method of evaluation is diver based inspection. LandScope are able to offer innovative solutions to the bridge maintenance sector, based on the latest proven technologies.
Specialising in mapping, measuring and modelling above ground, below ground and underwater, Landscope provide the capability to acquire high resolution LiDAR, photography and SoNAR from a number of methods which are best suited to the type of bridge, the bridge span and the location.
Each project undertaken is custom designed to ensure the safest and most efficient solution and the highest accuracy and resolution deliverable. As an example, scour risk assessment and below water asset condition is better understood from a high resolution, geometrically correct SoNAR point cloud than from traditional diver based inspection. Click here for an example of a bridge inspection project undertaken utilising this method.
We are delighted to announce the appointment of a new surveyor, Jim Williams.
Jim has taken up post based at our office in the South East, and will specialise in service tracing, GPR acquisition and processing, positioning and CAD.
Prior to joining LandScope Jim worked as a field archaeologist, and excavated many sites, most notably the York Minster undercroft.
In order to better serve the increasing demand for LandScope services in the South West we are pleased to announce the establishment of an office and operational base in Plymouth.
Within the first month we have already supported four prestigious projects from the new Plymouth facility.
The 16th annual Surveyor Highway Maintenance Conference is to be held on 30 May 2014 at the Nottingham Belfry, and once again LandScope will be exhibiting.
The event, which is the industry source for all sectors involved in maintaining essential highway infrastructure, will this year see a focus on SUDS – Sustainable Urban Drainage Systems, a key issue following the sustained flooding suffered by many parts of the country in early 2014.
LandScope can be located on Stand 5 at this event. For more information on the Highway Maintenance 2014, click here
LandScope’s dedicated inshore survey launch ‘Polecat’ is currently engaged on a survey of the Norfolk Broads.
The three year programme will provide bathymetric data over much of the Broads network, enabling the Broads Authority to design an informed and cost effective dredging campaign.
The ‘Polecat’ has recently benefited from the upgrade of GNSS sensor to the Trimble R10 – providing greater 3D positioning stability even in the most challenging vegetated banks of the Broads’ rivers and lakes.
LandScope has recently completed a detailed laser scan survey of the Judge Business School at the University of Cambridge.
Developed at the site of the old Adenbrooke’s Hospital, the Judge Business School has a unique architectural style which makes it a most challenging subject for measured building survey.
The employment of laser scanning at an early stage of a re-development programme has again highlighted the many advantages of the technology – providing not just for the derivation of as-built drawings but also a complete 3D model from which all stakeholders may benefit.
LandScope recently completed a structural radar survey at The Parrot House, Eaton Hall.
We were tasked with the investigation of condition and identification of the basic construction of the 133 year old terracotta building. The results of the structural radar survey will be a key part of the structural assessment as part of the building’s conservation.
The original function of The Parrot House was to provide suitable accommodation for exotic birds, and central heating was installed for this purpose, however there are no records to demonstrate it was ever used in this capacity, although the estate website confirms it did house a few budgerigars in the late 1900s.
The stunning surroundings of Capel Curig in the heart of Snowdonia were recently the location for a bathymetric survey to create a digital terrain model of a natural lake. Given the lake is a Site of Special Scientific Interest (SSSI) the survey craft had to be man-powered rather than deploying the usual outboard motor.
Employing a Canadian canoe the surveyors obtained depth data which was processed via AutoCAD Civil 3D software to create a high resolution model which was subsequently integrated to the onshore topographical survey.
LandScope specialise in high order inshore and nearshore hydrographic surveys and apply the appropriate technology configurations to meet each individual project need.
Our mobile mapping service autoMAP has been commissioned by the University of Hertfordshire Automotive Engineering Department to acquire track data as part of the preparations for the forthcoming Formula E track in the centre of London.
Formula E is the new FIA motor racing championship featuring electric cars, due to commence in 2015. There are currently 10 rounds in the calendar with London pencilled in for June 2015.
LandScope’s autoMAP mobile mapping service has acquired high resolution panoramic imagery, into which are embedded millions of laser scanning measured points. The resulting data acquired from the London track will be used to create an accurate and detailed environment model as well as providing vital information on the topography of the track itself.
An exhibition of leading service providers to the bridge engineering and maintenance sector attracted a large number of visitors at the 2014 Bridges Conference.
Now in its 22nd year, the event was held on 26th March at Edgbaston Stadium in Birmingham, and attracted top level industry specialists, engineers and bridge operators.
LandScope showcased its latest projects and case studies which have benefitted from a versatile combination of SoNAR, LiDAR, photogrammetric and Impulse RaDAR technologies. The ability to provide customised survey solutions based on leading edge technology enables LandScope to provide the highest level of resolution and accuracy, both above and below water, to the challenging work of bridge inspection and survey.
Collaborating with LandScope at the event was Teledyne Blueview, who provide LandScope with the latest underwater 3D sector scan sonar solutions. Results from a recent survey may be viewed in the attached video.

Back in June, LandScope Engineering was re-awarded with its ISO9001 quality management system accreditation. The product of many years hard work by LandScope employees, the foundations were in place long before accreditation was first sought. Building on previous years, the management system continues to flourish and add value and depth to all of LandScope’s services. An intensely practical system that allows freedom, whilst maintaining and improving standards the external auditor commended the system on its excellent record keeping and documentation, superb internal audit system and stellar non-conformance and corrective action approach. Momentum builds towards the next assessment period with many new and innovative data management and acquisition procedures, bolstering the many business functions within LandScope Engineering.
LandScope Engineering has embarked on a multi-discipline survey exercise in association with the Shropshire Mines Trust. Snailbeach Mine is within a few miles of LandScope Engineering headquarters in Shropshire and was, at its peak, amongst the most productive mines in the Europe (Fred Brook & Martin Allbutt_The Shropshire Lead Mines_1973). For many decades inactive, there is now an established team who maintain, develop and show visitors around the extensive surface buildings and within some of the mine workings themselves. LandScope personnel were able to access the mine through Perkins Level and the workings within; referred to locally as ‘The Cathedral’, on account of the rising spire like extraction of rock and minerals, or stope. The stope reportedly rises to within a few metres of the surface and it is possible to see day light from the ventilation shaft directly above.
The aim of the project is to produce a 3D model of The Cathedral using a Faro laser scanner and tie in with geophysical surveys on the surface to robustly establish the depth of cover above The Cathedral. There are earth workings on the surface to prevent tractors and other heavy machinery driving over the top and some anecdotal evidence from older locals puts the depth of cover at ‘a few feet’. LandScope has employed the use of microgravity, resistivity and low frequency ground penetrating radar to map the depth and make-up of the subsurface above The Cathedral. A topographical surface model was created and an Ordnance datum traversed down through woodlands and into the mine for registration of laser scan setups.
Perkins Level is over 50 vertical metres below the surface working on Lordshill above and having spent a day underground, survey personnel had a first-hand taste of what it must have been like to work there full time but can only imagine how tough it must have been to mine the lead, zinc, fluorspar and barites (white material on the left above person in photo). Cramped, dark, very wet and cold conditions made it difficult to survey, let alone mine and all were very happy to see day light at the end of the survey! A fascinating place on a mind boggling scale (workings extend well over 250m below sea level, with Perkins level at 278m above ODN), anyone one interested in the mine can find lots more information at: http://shropshiremines.org.uk/snailbeach/sbinfo.htm and it is well worth a visit.
Many thanks to Andrew Wood from the Shropshire Mines Trust for taking us into the mine and being a very useful survey assistant! And to Ian Cooper for the use of his photo.
autoMAP was commissioned to produce a mobile laser scan of the Brands Hatch track in Kent for the purpose of gaming simulation. The project requirement was to produce a highly accurate framework to model the track, pit areas and surrounding environment in order to produce a virtual world which is ever more closer to reality.
The developer diary has now gone live and the track became available to players mid-October.
For more information and video, please click Brands Hatch

A Dacia Duster has been custom fitted to ensure maximum productivity and deployment flexibility. Offering 4 Wheel Drive and splendid all-round manoeuvrability the vehicle will serve both traditional highway mapping and the ever-increasing off-road applications.
Please look out for it. We will tweet so you will know it’s whereabouts.
Please see the autoMAP website for further details.
Field staff from LandScope Engineering recently attended a Technical Seminar on ground penetrating radar (GPR), provided by Mike Langton from the GPR supplier MALÅ. The course covered theory and application of GPR, and acted as a platform to discuss best practices. The seminar also allowed direct comparison of the GSSI and MALÅ GPR systems.
Assistant Surveyors Ben Davenward and Jo Painter have recently completed The Survey Association Land Survey Techniques Course. Designed to give surveyors a good grounding in the principles and practical application of surveying, the five day course involved both the use of survey equipment outside and theoretical work back in the classroom. Topics covered included levelling, traversing, resection and detail survey.
Ben and Jo are now looking forward to implementing what they have learned on the course in their work at Landscope.
LandScope are currently engaged in a large scale autoMAP project for a Local Authority. The Topcon IP-S2 is being utilised to acquire the mobile mapping data and once post processed, it is then made available for the data extraction team.
The in-house data extraction team are utilising Orbit Asset Inventory Management (AIM) software to capture large volumes of highway assets (using a point and click methodology) e.g. non illuminated traffic signs, drainage and verges to name a few. A full database is being populated with either a series of point, line and polygon features, some of which have additional attribute information captured to enrich the data extracted from the mobile mapping content.
As a participating member of TSA’s Continuing Development Scheme, we are pleased to receive CCD Certification for the forthcoming year.
LandScope have recently completed geophysical survey works at BAE Birtley.
Founded in a hurry by David Lloyd George in 1915 the site was integral to war efforts during both the Great War and World War 2. In the early days the site was manned predominantly by Belgian volunteers – the Birtley Belgians – sourced from the frontline and from the pool of injured soldiers.
LandScope were tasked with the mapping out of numerous concealed construction pits, air-raid shelters and other underground infrastructure.
The results of the geophysical survey will be integral to the land remediation process as part of the site’s redevelopment.
Tasked with reducing office processing time, improving cartographic consistency and further refining field data collection techniques, the LandScope survey team set to work with software developers AIC to enhance the functionality of their AutoCAD plug in system 4Site.
Significant improvements were made with the integration of LandScope’s Trimble feature code library and 4site to unlock the drawing potentials of the software. Changes were made to fit LandScope procedures but performed in a manner that would benefit the development of 4Site as a whole.
AutoCAD and 4site sit at the centre of LandScope deliverables, integrating key services such as autoMAP, geophysics and utility mapping. Therefore it was imperative to have a CAD based system that would allow for consistency and future development.
In order to make the system all the more robust a field detail manual was constructed to clearly document how to best use attribute data and field techniques to improve efficiencies and quality in both the field and office.
LandScope have extended their laser scanning service portfolio to include long range scanning. Recently LandScope were involved in a programme to monitor a section of quarry wall from a distance of circa 700m. The wall is suffering from an expanding fissure. By utilising the latest Maptek 8800 scanner, LandScope were able to accurately model the fissure with the aim of returning on a regular basis to monitor any movement.
Jim Williams and James Kilroy have recently completed their trek of the Annapurna circuit. The circuit consisted of walking through tropical forests, wind-swept desert valleys and mountain top routes. At 5416m the Thorung La pass is the highest mountain pass in the world, at which oxygen levels are half that of low altitude heights. Fortunately the team made it through with no serious altitude sickness problems and was privileged to see some of the most truly stunning scenes in Nepal.
Man made cave systems lining ancient or historic trade routes are a common feature of the Mustang region of Nepal. Approximately 10,000 caves exist in this region but relatively few have as yet been explored. The rock is extremely friable and erosion rates are high. LandScope was involved in the 3d mapping of cave systems at approximately 3400m which has produced a plan that will be available long after the caves themselves are no longer present.
At an altitude of approximately 2800m LandScope were involved in the mapping of field terraces associated with a medieval village. Recent ploughing of the field system has brought many artefacts to the surface and these items were marked, documented and positioned onto the plan. Archaeological investigations have revealed that the horizontal dispersal of artefacts once buried in ploughed soils is minimal and plotting finds onto a plan can help identify future excavation locations.
LandScope employee James Kilroy is shortly setting out to Nepal as part of a small group of archaeologists. The Himalayan Exploration and Archaeological Research Team (HEART) will be surveying mountain plateaus and entering man-made cave systems along the Annapurna circuit and the Mustang region of Nepal. It is hoped that research will help shed light on one of the earliest spice trade routes in the world as well as place Nepalese prehistory into its wider context. Supported by LandScope equipment and funding, James will be responsible for mapping these high altitude sites and placing surface scatters into a coordinate frame.
LandScope Engineering recently supported a community archaeology group investigating aerial photography near Eardisland, Herefordshire. Using the Bartington magnetometer, LandScope were able to produce a geophysical survey of the suspected site. Data revealed that not only were the crop-marks resultant of ditch/bank enclosures but that there was strong evidence of pits or structures within the enclosure. Additionally, survey revealed that the enclosure system appeared to extend out beyond the area of photographed crop-marks, suggesting further areas of archaeological interest.
The nature of the site is strongly reminiscent of an Iron Age or Romano-British enclosure and the high quality of the survey results may indicate a good level of preservation. With these survey results accurately positioned within the Ordnance Survey grid, it is hoped that future excavations can be targeted to best understand the history of this site and place it within its wider archaeological context.
LandScope have recently completed a topographical survey of RAF Lyneham in preparation for its conversion to a defence technical training centre scheduled to be operational in 2015. The base, which is over 470 hectares in size, was one of the busiest military airfields in Europe before it was decommissioned.
The survey was completed over a 5 week period in September and October 2012 using traditional total station and GNSS survey methods. The model was augmented with the use of LandScope’s mobile mapping system, autoMAP, including 3D LiDAR data and panoramic photography from which additional topographical and other data has been extracted.
LandScope Engineering has recently been awarded a long term dam monitoring project in Wales.
The scope of work is to include the installation of survey monumentation and target systems – to be used over a 25+ year period.
Survey measurement will be conducted with Trimble S8 total station and Leica laser scanning systems.
The Faro Focus 3D laser scanner has recently been used to carry out dimensional survey of five giant aircraft hangars at RAF Lyneham. Given the restrictions of other traditional methods in surveying such large and irregular structures, Landscope relied upon the Focus 3D to generate high resolution point clouds of each hangar both inside and out.
The scan of a single hangar was completed by a single surveyor in just one day.
The point cloud data sets were subsequently used to create an accurate 3D model and generate accurate 2D floor plans, elevations and sections.
With increased demand for its 3D Modelling service, LandScope has recently added a Faro Focus 3D system to the fleet.
Within a matter of weeks the Faro Focus has already completed over a dozen projects including:
The versatility and portability of the Faro Focus 3D unearths more applications for the laser scanning service.
LandScope has become a participating member of TSA’s Continuing Company Development Scheme.
