Photogrammetry is one of those technologies many people rely on without realising it. If you’ve looked at a detailed aerial map, explored a 3D model of a site, or reviewed a drone survey, there’s a good chance photogrammetry was behind it.

What is photogrammetry?

At its simplest, photogrammetry is the process of using digital photographs to measure and map the real world. By taking multiple, overlapping images of the same area from different angles, specialist software can identify shared features and calculate their size, shape and position. The result is an accurate, measurable representation of the environment, ranging from 2D plans to full 3D models.

Put simply, photogrammetry turns digital photos into reliable, usable data. While the principle has been around for over a century, advances in digital cameras, drones, computer power and processing software have transformed what is possible to achieve, making photogrammetry faster, more accessible, and more cost-effective than ever.

Why is photogrammetry important?

Photogrammetry is widely used across construction and engineering, planning and design, asset management, heritage, and environmental monitoring. Its main strength is the ability to capture large amounts of data quickly and safely. In many cases, information can be collected remotely using drones or aircraft, reducing the need for surveyors to access difficult or hazardous areas.

For clients, this means faster site data capture, reduced disruption and safer workflows.

It isn’t just used for large scale areas – it can also be used to capture artefacts and objects in high detailed in controlled conditions with DSLR (Digital Single-Lens Reflex) cameras.

Does photogrammetry just produce images?

Photogrammetry produces measurable survey data that can be used throughout a project. This can include:

• Orthophotos – accurate aerial images you can measure from
• 3D meshed/textured models – ideal for visualisation and analysis
• Point clouds – dense datasets similar to laser scanning

With the correct geospatial survey practices where survey control, GCPs (Ground Control Points) and targets, are deployed – these outputs provide visual clarity and technical accuracy, helping teams make better decisions from the outset.

The resulting 3D data can be combined with 3D laser scan point cloud data and traced to produce CAD drawings, or help build 3D models in software like Revit– ready for use in design and planning.

What are the benefits of photogrammetry?

Photogrammetry offers several key advantages:

• Non-intrusive data capture (no digging or physical contact)
• Rapid collection of large datasets
• Access to areas out of visual line of sight from the ground for laser scanners
• Highly detailed, visual outputs
• A permanent digital record that can be reused over time if survey control is used

However, it’s important to recognise that results depend on good planning, high-quality imagery, and professional geospatial survey expertise. When a drone is deployed, it is important that the pilot is licenced, experienced, has gained all the relevant permissions and authorisations, and fully is insured. While the technology is more accessible, producing reliable, survey-grade data still requires experienced practitioners.

Why should you care about photogrammetry?

For clients and stakeholders, the value is straightforward. Photogrammetry gives you rich, visual data you can measure, analyse and rely on throughout your project. Used correctly, it can improve understanding, reduce risk, and support better decision-making, from early planning to final delivery.

This is just an introduction. For detailed guidance on specifications, workflows and procurement, download the full client guide from The Survey Association website.

Preserving our past

3D Geospatial Surveys are the ultimate way of recording and keeping track of the condition and change in old buildings. These types of specialist surveys, guided by Historic England’s specification, will capture buildings, important sites, structures and even landscapes in high detail and accuracy. It is useful data for government, councils, conservation specialists, estates, and private owners to evaluate and maintain their assets, providing a snapshot for present and future guardianship.

The 3Ddata, drawings, and models are then used to inform planning or conservation decisions, to ensure that any intervention balances the need for modernisation or retrofit with conservation and preserving the historic fabric. In this way, we can both preserve the past and ensure a future for these buildings and monuments, with the emphasis on their importance and place in our cultural landscape.

Protecting the future

A heritage geospatial survey provides accurate, reliable measured data to support the understanding, conservation, repair and long-term management of historic buildings, structures and landscapes. A specialist geospatial surveyor will be guided by Historic England’s Geospatial Survey Specifications for Cultural Heritage (2024), selecting appropriate methods according to the significance, complexity and intended use of the site or asset.

This may include desk-based preparation, review of existing information, site assessment, survey control, terrestrial laser scanning, mobile mapping, photogrammetry, GNSS, UAV survey, topographical survey and measured building survey techniques. The objective is not simply to produce a “normal as-built survey”, but to create accurate, appropriate and well-structured geospatial data that records the form, position, geometry and spatial relationships of the heritage asset.

Depending on the project requirements, this data may document architectural features, such as windows, staircases, doorways, arches, roof structures, floor levels, wall alignments, decorative elements, and areas of deformation or movement. It can also support condition surveys, conservation planning, structural assessment, archaeological interpretation, retrofit design, maintenance strategies, and future monitoring.

Heritage geospatial surveys are therefore an essential part of responsible conservation practice. They help ensure that decisions about repair, adaptation, development, renovation or retrofit are based on accurate information, reducing the risk of avoidable damage to historic fabric and helping protect irreplaceable cultural heritage for the future.

Building trust and confidence

TSA Council Member Andy Beardsley MRICS, a chartered geospatial surveyor and Managing Director of Terra Measurement, has spoken extensively about the importance of Heritage Surveys and their place in the surveying landscape.

“For over 30 years, I’ve worked in geospatial survey measurement and monitoring, much of that on historic structures. And what concerns me today is not technology or software, it’s decision-making. Because the risk to heritage today is no longer a lack of care, it’s false confidence in inadequate information. Information that looks complete because it’s detailed, because it’s visual, because it’s been modelled, but it hasn’t been fully verified. So, decisions get made, designs progress, procurement follows, and the risk is already embedded. ‘It looks detailed’ is not the same as being right.

“Every time we measure an historic building, we are making a decision about how well it will be understood, not just today, but in the future. There is a campaign by The Survey Association that has just begun and it puts this theme more bluntly. If geospatial surveyors stop tomorrow, the cracks begin to show. But this is a metaphor. It’s not just about physical cracks. It’s cracks in coordination, in communication, in confidence and in the financial stability of construction projects. Because when the information isn’t reliable, teams stop trusting it – and when teams stop trusting the information, they start to make their own decisions on site, under pressure, without a shared reference point or survey. And that’s where risk multiplies.”

Depth of knowledge

The answer, of course, is “All at sea”. Hydrographic surveys are an important aspect of global mapping and are useful at finding a myriad of features and structures concealed by water. In the same way that underground utility surveys reveal what lies beneath ground level, hydrographic surveys explore the depths of various bodies of water. They are a practical way to explore oceans, the sea, inlets, harbours and coastal areas, lakes, rivers, meres, pools, estuaries and other watery expanses.

Hydrographic surveys map areas such as ocean floors and riverbeds, to show how the ground undulates and indicates depths and other data. They can be used for civil engineering projects, such as bridges, or for maritime projects like dredging or environmental issues. They can also map the ocean floor for navigational purposes.

Expansive projects

River and canal surveys have defined parameters and follow the course of the waterways, whereas oceans and seas are more complicated and expansive, requiring survey vessels and other equipment. But they don’t just explore and map subaquatic landscapes. They are also used by maritime industries, construction firms, insurance companies and government agencies to inspect, map and evaluate submerged structures and vessels. They are essential for ensuring the safety and maintenance of bridges, harbours and waterways, docks, oil rigs and pipelines, as well as checking the condition of boat hulls and the position of wrecks.

The importance of geospatial surveyors is exemplified by the number of sectors the profession can be involved with – everyone from environmental campaigners, cartographers and construction projects, to local councils, planners and lawyers settling boundary disputes. Hydrographic surveys are another discipline and a specialist area of surveying knowledge, with its own equipment and skillsets. Once collected, the digital data can be processed to create digital models and 3D views of the terrain or structure. This information is invaluable, as so much beneath the waterline is unseen and unknown.

Dive into a new career in geospatial surveying

The breadth of knowledge required to be a surveyor goes beyond maths and an ambition to work outdoors. There are many different disciplines that feed into surveying and people with all kinds of backgrounds enter the profession. The flexibility and appeal of working outside and inside – not simply being office-based – is a big draw for many people. It’s also a career that can be learned and enhanced whilst doing the job. This can be via apprenticeships, with professional qualifications available and ongoing development an option, through courses such as The Survey School curriculum and other organisations and bodies.

From mapping out the next city skyscraper to ensuring your local school is built in the right spot – surveyors play a key role in land development, construction, mining, transport, and environmental projects. Yet despite being essential to construction, planning, engineering, and property, surveying too often remains a career that people come across, rather than actively seek out.

Read on if you’re curious about what a career in land surveying actually looks like, and how to get started.

What does a surveyor actually do?

At its heart, land surveying is about measurement and spatial understanding. Surveyors determine the precise positions of points on the earth’s surface, establish boundaries, and produce data that underpins everything, from planning applications to multi-million-pound construction projects. Surveyors work in lots of different places, using a mix of technical know-how, problem solving, and people skills. Depending on your area of specialism, you might find yourself:

• Conducting topographic surveys to map the features of a site before development begins
• Carrying out measured building surveys to capture the geometry of existing structures
• Performing utility surveys to locate and map underground services
• Undertaking lease plan surveys or boundary surveys for legal and property purposes
• Using laser scanning and drone technology to capture highly detailed 3D datasets
• Working in monitoring roles, tracking the movement of structures, slopes, or ground over time

Geospatial surveying is a career on the rise, with demand growing across many industries. No two projects are quite the same, and no two days in the field are identical.

Who is surveying suitable for?

Surveying suits people who enjoy enjoy technology, being outdoors, and solving problems, who have a methodical mind, and who take pride in the accuracy of their work. You don’t necessarily need to have come from a technical or engineering background to find your footing in the profession. Many successful surveyors have entered the industry from construction, the military, a geography background, or even completely unrelated fields.

When it comes to building a career in surveying, what matters most is an aptitude for precision, a willingness to keep learning, and having practical curiosity about how things fit together in the physical world.

The importance of recognised training

Becoming a surveyor means learning the right technical skills and getting hands-on experience. While enthusiasm and aptitude will take you far, land surveying is a profession that demands formal, recognised skills. Equipment such as total stations, GNSS receivers, and terrestrial laser scanners requires proper training to use effectively – and the data you produce will be relied upon by engineers, architects, planners, and solicitors. Getting it wrong has real consequences but getting it right, consistently, is what defines a professional surveyor. This is where practical training becomes invaluable.

The Survey School: training for the real world

The Survey School, based in Worcester and part of The Survey Association, exists precisely to meet this need. It’s a leading provider of land surveying training, offering a wide range of courses that cater to everyone from complete beginners taking their first steps in the profession to experienced practitioners looking to extend their competencies or gain qualifications in new areas.

What sets The Survey School apart is its emphasis on hands-on, practical learning. Courses are led by instructors with genuine real-world experience, and the training is designed to equip attendees with skills they can apply from day one.

A breadth of training to support every stage of your career

Whether you’re just starting out or looking to diversify your existing skill set, there is almost certainly a course that is perfect for you.

The Survey School’s programmes are designed to flex around working lives. Many courses run over just a day or two, making them accessible to those already in employment who need to build specific skills without taking extended time away from work. Others are more intensive for those who want to immerse themselves in a new discipline.

For experienced professionals, the school’s courses provide a structured route to continuing professional development (CPD) – something that is increasingly important for maintaining memberships with professional bodies such as the Chartered Institution of Civil Engineering Surveyors (CICES) and the Royal Institution of Chartered Surveyors (RICS), both of which are closely linked to The Survey Association’s professional standards framework.

A career with real prospects

Land surveying offers strong long-term career prospects. Skilled surveyors are in consistent demand, and the profession has proved resilient through economic cycles because the need to measure, map, and monitor the physical world doesn’t diminish. The growing adoption of technologies such as laser scanning, drones, and BIM (Building Information Modelling) is creating new opportunities rather than replacing human expertise – surveyors who combine field skills with technological literacy are particularly well placed.

Learning in-demand skills, like working with GIS tools or flying drones, can give you a real edge in the job market. Progression is merit-based, and there is genuine scope to move into project management, consultancy, or specialist technical roles. Many surveyors also work independently, running their own businesses once they have built up experience and reputation.

Ready to take the next step?

Whether you’re considering a career change, looking to formalise skills you’ve developed on the job, or wanting to add new capabilities to an existing practice, The Survey School offers a clear and practical pathway forward.

As the training arm of The Survey Association – the trade body representing the land surveying profession in the UK – The Survey School brings together industry knowledge, professional standards, and practical expertise in a way that few other training providers can match.

Stronger networks, stronger profession

The major events we create for our members continue to grow in scope and attract increasing numbers. This year’s AGM at Wembley saw nearly 60 survey businesses represented. As well as enjoying vibrant round table discussions on subjects close to our members’ hearts, including equipment theft, education and skills, fees and client education, the afternoon ‘Robot Wars’ session, along with the stadium tour added to the collaborative feel and opportunities to network.

Last month’s Conference and Awards Day was the best attended event in TSA’s history and we were delighted with the positive feedback from members, The Survey School delegates and the apprentices who attended. Mandy Hickson’s presentation was truly awe-inspiring, with fantastic insights into leadership,teamwork and members left armed with insights that directly improve their businesses. Plans are now well underway for our TSA AGM in March 2026 at Twickenham with the aim to continue to build community but also provide a place for members to contribute, inform and be informed.

In May next year we will also be returning to Utility Week Live. This will build on the progress we made in attending Europe’s only pan-utility exhibition this year to promote our PUMA scheme and talk to clients about the importance of best practice and raising standards when it comes to delivering surveys that comply with the PAS128 specification. TSA will also be offering more valuable CPD sessions to clients, working hard to raise standards and promote the vital importance of geospatial skill and expertise.

Tackling challenges head-on

2025 has also seen the establishment of our new partnership with NCATT (National Construction and Agriculture Theft Team), a dedicated unit within Northumbria Police, to address the continued threat of equipment theft, the consequences of which affects everyone involved in the geospatial profession. We have joined the Donor Group, which consists of the Construction Equipment Association, Construction Plant Association and Hire Association Europe, as well as insurers and suppliers. We are working closely with NCATT on this pressing concern for the good of all survey businesses and we look forward to sharing news of action being taken.

Relentlessly investing in the future

TSA funded the original project to create both Level 3 and Level 6 Trailblazer Apprenticeships for those wishing to train and gain a recognised qualification in surveying. We continue to be absolutely committed to supporting the roll out of Geospatial Apprenticeships across the country and it was fantastic having three apprentices attending last month’s Conference and Awards Day to receive the inaugural Best Apprentice awards. We are delighted that we now have T3 Training, along with Riverside and Dudley Colleges offering the Level 3 Geospatial Survey Technician Apprenticeship and we look forward to reporting further good news on this front in the weeks and months ahead.

Mark White, the company’s commercial director, provides some insights into Landscope’s experience of becoming PUMA accredited.

PUMA has really been a question of formalising and documenting our standard practices; providing customers with the highest level of confidence that our utility surveys are being delivered to industry standards

What is your involvement with utility surveys?

LandScope regularly undertakes utility mapping surveys in line with PAS128:2022 guidance. We undertake a variety of utility surveys, ranging from large scale military bases, road improvement schemes and utility network providers to smaller projects of varying complexity. Our capability extends into the marine environment, leveraging our specialised sensors to locate underwater cables and pipes.

Why do you think PUMA is important?

As a leader in the geospatial sector, Landscope prides itself on being an early adopter of new standards and technology; we were an early adopter of GPR technology for utility mapping back in 2004 (prior to PAS128 guidelines being introduced). This mind-set was a primary reason that becoming PUMA accredited appealed to us.

Prior to PUMA, it would have been challenging for industry customers to have confidence that a requested utility survey would meet PAS128 compliance (unless familiar with PAS128 specifications). We believe that adoption of PUMA across the sector will help drive an increase in quality and compliance, across the industry.

How did you find the process of applying for accreditation?

It was very encouraging to discover that during the on-site audit, the competent assessor would ask probing questions, challenging our established procedures. It was certainly not a simple tick box exercise!

We found the entire process rather enjoyable. It was affirming to learn that we have been exceeding the PAS128 requirements as standard. Working towards PUMA accreditation has meant that we can now further evidence our professional standards.

What impact do you think being PUMA accredited has had/ will have on your business?

From a commercial perspective, we operate in a highly competitive market. We hope that PUMA will help ensure fairness when competing with other PUMA accredited suppliers, giving clients the confidence that quoted surveys will be competed to an equivalent standard.  PUMA goes a long way in supporting rates that are commensurate with our profession – something all competent survey companies will benefit from.

What advice would you give anyone thinking about starting an application for PUMA accreditation?

As PUMA becomes more widely adopted, leading to an increase in client awareness, PUMA will very quickly become a commercial prerequisite. Ensuring survey businesses conform to the standard will help to reverse the current race to the bottom practices, compromising quality and safety.

As well as the commercial advantage, going through the PUMA accreditation process is an excellent way of auditing your internal procedures, giving the organisation confidence in both their employees and general working practices.

Powers and utility surveys

Powers is a long-established geospatial survey firm in North West England, serving the architecture, engineering, and construction sectors for more than 50 years. The company delivers a full range of geospatial services, including:

• Measured building and topographical surveys
• 3D laser scanning, mobile mapping, 3D Revit modelling, UAV (drone) surveys
• Site‑engineering work like setting‑out, machine control, ground modelling, as‑built surveys, deformation monitoring
• Underground utility detection (PAS 128 compliant and PUMA accredited)

The Powers team brings deep expertise in hi‑tech, high‑precision surveying and works throughout the UK. Powers holds ISO accreditations for Quality (ISO 9001), Health & Safety (ISO 45001), and Environmental Management (ISO 14001), enabling the company to work in the aerospace, defence, and aviation sectors. Powers’ approach is hands‑on, emphasising building relationships with clients to better understand their needs, delivering value within budget and time constraints and supporting decision‑making from early stages in projects.

Why do you think PUMA is important?

In the UK, there’s no mandatory rule governing how underground utility surveys are carried out. Quality varies widely. Being PUMA-accredited tells clients that your surveys truly follow PAS 128 and that your processes are independently audited. That builds trust swiftly, cuts ambiguity in bids, and reduces risk on site. Clients choosing a PUMA‑accredited firm know what they’re getting: independent verification that the surveys meet PAS 128:2022 standards. That spares them from time-consuming due diligence and reduces the chance of buried‑utility surprises, costly delays, or even injuries on site.

PUMA isn’t just a badge. It creates a consistent, national standard for utility surveys by TSA (The Survey Association) and is managed by LRQA (a global leader in quality assurance). Every accredited company is audited against processes, staff competency, risk management, and transparency in results.

How did you find the process of applying for PUMA accreditation?

Earning PUMA isn’t a one‑and‑done. First comes an office systems audit; then on‑site validation of survey methods; then periodic surveillance during the three‑year accreditation period—so the standards are maintained.

As we are already ISO 9001, 14001 and 45001 certified, the external PAS 128 audit was very similar to our external ISO Standard audits so we didn’t have to change much in order to get through it. All of our projects are subject to high quality standards, so it was a case of communicating this well to the auditor. Unlike our ISO auditors, the PUMA auditors understand the geospatial profession as they also audit NERS (National Electricity Registration Scheme), WIRS (Water Industry Registration Scheme) and GIRS (Gas Industry Registration Scheme) companies. LRQA’s PUMA auditors therefore understood the nuances of underground utility detection to a very deep level which means our clients can be assured we are rigorously checked to a high standard. We passed first time with flying colours and will continue to do this in the future.

What impact do you think being PUMA accredited has on your business?

Having PUMA accreditation helps us to communicate effectively and quickly with clients and establish a clear quality benchmark for our underground utility surveys. Our clients are clear about what they are getting and know that they can leave the technical detail to the experts when dealing with Powers. We believe that all utility surveyors should have a requirement to be PUMA PAS 128 accredited so that the quality of underground utility detection in the profession remains high and standardised.

What advice would you give anyone thinking about starting to apply for PUMA accreditation?

Go for it! The audit is a methodical process and if you’re doing everything correctly and you’ve been following the PAS 128 specification anyway, then you should sail through the audit. It really helps when explaining what we do to potential clients who come from a variety of backgrounds and who may or may not understand utility detection.
