PROVIDING NEW IMMERSIVE INSIGHTS
3D Photogrammetry.
3D Photogrammetry is revolutionary for use in Arboriculture, giving us the ability to transform photographs into accurate, fully textured 3D models, and we use it to capture a range of subjects from the smallest tree defects to entire tree populations, woodlands, and forests. From pinpointing and analysing tree defects to creating comprehensive site drawings, our use of photogrammetry redefines precision in arboriculture and elevates your tree surveys and reports.
Combined with our use of drones, we can turn drone photos and video into expansive 3D models. The same principles can also be applied with hand-held, DSLR cameras to create models of trees, tree defects or features, and site context including features and buildings.
What is
photogrammetry?
Photogrammetry is a technology that captures precise three-dimensional measurements and visual representations of objects, terrain, or structures using photographs
This includes felling, lopping, topping, uprooting, and other intentional destruction. Cutting roots is likewise not permitted and requires the written consent of the LPA.
It relies on advanced software to analyse multiple images taken from different angles, enabling accurate reconstruction and measurement of the subject.
​
Using photogrammetry, we produced a 3D model of a sycamore stump which had been felled following a Detailed Tree Inspection at a UK Theme Park.
BENEFITS OF PHOTOGRAMMETRY
-
Photogrammetry provides highly accurate and detailed measurements of trees, including their structure, dimensions, and potential issues.
-
Capturing 3D models allows for a thorough examination of tree health, identifying defects, disease, or structural concerns, post survey.
-
Photogrammetry can help to streamline the inspection process by enabling quick and comprehensive data collection, reducing the time required for on-site assessments. This is particularly useful where time constraints or access restrictions restrict surveys.
-
Clients receive visual representations such as 3D models and orthoimages, enhancing their understanding of tree conditions and aiding in decision-making.
-
The technology facilitates ongoing monitoring, allowing clients to track changes in tree health over time without the need for frequent on-site visits.
We can help you help your clients with photogrammetry.
From ground to air using our fleet of drones (or our mini innovators), we can create scans, 3D models, and capture 360 video. In addition, the use of photogrammetry creates photorealistic models in high definition that can be viewed traditionally on 2D screens or in Virtual Reality (VR).
​
In addition to utilising cutting-edge photogrammetry techniques for our own tree surveys and reporting, we offer a comprehensive suite of photogrammetry services to other organisations which includes:

EXPERIENCED TREE CONSULTANTS HELPING VETERAN TREES
How photogrammetry helps your project.
Photogrammetric surveys are perfect for recording trees where a very high level of detail is necessary, for example compiling a comprehensive record or inspection of an irreplaceable ancient or veteran tree during Veteran Tree Surveys. We can capture details on individual features, cavities or hollows, allowing our team, you and future conservators to view the trees remotely with exceptional clarity, with a greater level of accuracy than traditional techniques.
INFORMED DECISION-MAKING
With our use of photogrammetry, you gain a detailed understanding of your tree assets, empowering you to make informed decisions regarding maintenance, preservation, or removal.
The data collected can be used to share information with specialists around the world, allowing them to view objects, features and trees remotely. For local authority Tree Officers or Developers engaging with the public and local communities, 3D models produced using photogrammetry can be vitally important for public displays.
COST EFFICIENCY
Early detection of issues through photogrammetry helps you address problems before they escalate, saving on potential costly damages or emergency interventions.
3D TREE INVENTORY AND MANAGEMENT
Using photogrammetry to create 3D models to develop comprehensive tree inventories for effective tree management, is one of our main use cases. These models can then be repeated to monitor changes in tree health and growth patterns over time.
TREE CONDITION AND RISK SURVEYS
We regularly capture detailed 3D models to assess the health and structural integrity of identified risk features, identify the presence of symptoms related to diseases or disorder once back in the office, or potential risks through accurate visual representation.
OTHER INNOVATIVE USES
For BS5837 Tree Surveys for Planning, the outputs provide accurate 3D models of tree opportunities and constraints which provides an invaluable design tool during the feasibility stages of a proposed development. It can also be used as an additional tool to assist local planning officers and tree officers in visualising and evaluating development proposals near trees.
​
Alongside surveying using a drone, photogrammetry can help to better-inform Visual Tree Assessments (VTA) of trees to inform accurate and reliable tree risk assessment and tree management recommendations.
Photogrammetry in Ecology.
We understand the reservations around substituting 3D models for true, real-life experience with trees, defects, potential bat roost features. However, we now have, for the first time in history, an immersive medium that bridges the gap between the classroom and the field.
PHOTOGRAMMETRY IN ECOLOGY
Photogrammetry can be used to capture high-resolution images of potential bat roost features, assess and document features such as tree cavities, crevices, or record evidence of bat roosts or points of entries in lofts and buildings, through detailed 3D models.
Photogrammetric data can be used in Biodiversity Net Gain (BNG), Phase 1 or UKHab surveys and assessments to enhance habitat mapping, and identify and monitor key ecological features.
ECOLOGY EDUCATION
In the realm of education, photogrammetry serves as a transformative tool for both arboriculture and ecology studies. For arborists in training, immersive experiences can be crafted through 3D models of diverse tree species, simulating scenarios for inspections, risk assessments, and proper pruning techniques.
Ecology and wildlife conservation studies courses are enriched with the integration of photogrammetric models depicting varied ecosystems and habitats, fostering virtual field trips to explore ecological features and biodiversity, providing students with practical skills and insights that transcend traditional educational boundaries.

What are the disadvantages of photogrammetry?
While photogrammetry offers numerous advantages, it's essential to consider potential disadvantages:
This includes felling, lopping, topping, uprooting, and other intentional destruction. Cutting roots is likewise not permitted and requires the written consent of the LPA.
-
Adverse weather conditions, such as heavy rain, winds, clouds, haze, etc. can affect the quality of photogrammetric data collection.
-
Photogrammetry may face challenges in capturing detailed information of species type and twig density, especially in areas with dense vegetation, as it relies on clear visibility from various angles.
-
High-quality cameras and software for photogrammetry can be expensive, impacting initial investment costs.
-
Effective use of photogrammetry requires specialised skills and training and you need to understand both the technology and the principles of accurate data collection.
-
While highly accurate, photogrammetry may have limitations in achieving centimeter-level precision compared to other survey methods, such as laser scanning.
-
When using drones, adherence to aviation regulations and obtaining appropriate permissions for aerial surveys is crucial, adding complexity and potential delays.

-
What is a Tree Risk Assessment?A Tree Risk Assessment is a type of tree assessment carried out by a professional tree surveyor or consultant, to identify tree risk features, condition, and the occupancy around the tree to judge potential risk and prescribe appropriate tree management. These assessments are also referred to as "tree risk surveys" or "tree condition surveys". The assessment takes into account not just the risk posed by trees on the Site, but also the surrounding context and potential impact on nearby highways, structures and people.
-
Why is Tree Surveying important?Tree surveying is important for several reasons and largely depends on the importance, or benefits of surveying trees, greatly depends on the type of tree survey and the outcomes you are seeking. Firstly, it helps to identify the species, size, and health of trees at your property or on a Site earmarked or Development. For a BS5837 Tree Survey This information is crucial for planning and development purposes, as it can help determine whether or not trees need to be protected or removed. Secondly, tree surveying can identify any potential risks and risk features that trees may pose, such as dead branches overhanging a carriageway or trees that present an increased risk of falling onto a pedestrianised area due to the presence of a structural impairment. Regular tree surveying across a tree population is important for ensuring the safety of people and property on the Site. Finally, tree surveying can help to identify any important ecological or environmental features that may be associated with the trees on a Site. This can help to ensure that these features are protected and preserved. Overall, tree surveying is an important tool for arboricultural consultants, homeowners, developers, and large landowners to ensure the responsible management and protection of trees and their associated environmental benefits.

What Tree Surveying techniques are there?At ARB Innovators, we offer a range of tree surveying techniques to suit your needs. These include: BS5837:2012: This is a British Standard that provides guidelines for assessing the impact of development on tree on or abutting your Property or a Site. The BS5837 tree survey involves one of our arboriculturist assessing the structural and physiological condition of trees and assigning a BS837 quality categorisation (denoted as category A, B, C or U) and remaining useful life expectancy. The written Arboricultural Impact Assessment involves an assessment of impacts from the proposed development and providing recommendations for tree retention and protection. The latest version of BS5837 was published in 2012. Tree Risk Assessment: This technique involves assessing the risk of trees falling or causing damage in high-risk areas such as public spaces, highways or near buildings. Typically, our initial level of survey using the principles of Visual Tree Assessment (VTA). This technique involves inspecting trees visually to identify any signs of decay, disease or structural issues. Detailed Decay-Detection: This technique involves using specialist equipment to investigate the internal structure of trees and identify any signs of decay or disease. Our team of experienced consultants will work with you to determine which technique is most suitable for your needs and provide you with a detailed report outlining our findings and recommendations. Aerial or Climbed Tree Survey: If a tree surveyor suspects that defects may be present in the upper crown of a tree but cannot determine their extent during a ground level tree survey, they may recommend a climbed tree condition survey.
-
How do I know if trees on my property are protected?Trees can be safeguarded under various designations, including Tree Preservation Orders (TPOs), Conservation Areas, or being part of a wider environmental or heritage protection scheme. Consult Local Authority Records: Your first port of call should be your local council's planning department. They maintain up-to-date records of all TPOs and Conservation Areas within their jurisdiction. Most councils offer an online search tool, but don't hesitate to contact them directly for the most comprehensive advice. Look for Official Documentation: If you've recently purchased your property, your solicitor may have provided details of any TPOs or Conservation Area restrictions as part of your conveyancing documents. These records can offer a clear indication of any protections in place. Engage with ARB Innovators: Our team at ARB Innovators have a deep understanding of local and national environmental regulations. We can conduct a thorough assessment, identifying any protected trees on your property and advising on the next steps. Understanding the protective status of your trees not only ensures legal compliance but also helps preserve amenity and ecological value for future generations.
-
Why might a climbed tree survey be necessary?Occasionally, defects in a tree may be apparent but their extent cannot be determined during a ground level tree survey. In such cases, the tree surveyor may recommend that a climbed, or aerial, tree condition survey be undertaken. Climbing the tree allows the surveyor to get a closer look at the tree's upper crown and assess its condition more accurately. At ARB Innovators (innovation being in our name) we also use drones to survey the upper crown of trees, which provides a non-invasive, safer and more efficient alternative to tree climbing.
-
What is a BS5837 Tree Survey?BS5837:2012 is a British Standard for Trees in relation to design, demolition and construction - Recommendations. BS5837:2012 provides guidance for managing trees on development sites. The standard sets out a framework for assessing the impact of a development on trees within and adjacent to the site, and for specifying appropriate measures to protect and retain trees wherever possible. The aim of BS5837:2012 is to ensure that the arboricultural, ecological, amenity and landscape value of trees is taken into account during the planning and construction of new developments. At Arb Innovators we provide expert advice on BS5837:2012 compliance, including tree surveys, impact assessments, method statements, and mitigation strategies.
-
What steps are involved in BS5837 Tree Surveys and Assessments?BS5837 Tree Surveys and Assessments are a crucial element of any construction or development project that involves trees or wooded areas. Here are some of the key components that are included in our surveys: 1. BS5837 Tree Survey: Our tree surveyors will capture a digital inventory of all the trees on or within influencing distance of a Site, including their accurate location using a GPS system or by measuring their distance from fixed points, tree species, measured tree height, stem diameter, and crown spread. 2. Tree Category Assessment: Whilst on Site, we will assess each tree and assign it a BS5837 Quality Category based on its value and importance. This will help to guide decisions on which trees can be removed or pruned and which ones must be retained. 3. Tree Constraints Plan: Following the survey, a tree constraints plan (TCP) is created to identify the limitations and constraints that the trees impose on the development. The plan includes information about the root protection areas (RPA), crown spread, and any other factors that may affect the trees. 4. Arboricultural Impact Assessment: An arboricultural impact assessment is conducted to evaluate the impact of the development on the trees. A Tree Retention and Removals Plan is produced to accompany the assessment, visually representing the impacts. We will evaluate the impact of the proposed development on the trees on the Site and provide recommendations for minimising damage or harm. 5. Arboricultural Method Statement (AMS) and Tree Protection Plan: Based on our assessments, we will develop a formal AMS which sets out the working methodology to ensure trees are appropriately protected during construction phases. The AMS will detail measures such as tree protective fencing, signage, and arboricultural supervision to prevent damage to the trees. At Arb Innovators, we are committed to providing our clients with the highest quality tree surveys and assessments, and we work closely with our clients to ensure that their projects are completed in an environmentally responsible and sustainable manner.

What should I expect in a BS5837 Tree Survey Report?A BS5837 Tree Survey Report is a comprehensive document that provides a detailed analysis of the trees on a site and their relationship to the proposed development. This report is essential for developers, architects, and planners who are looking to obtain planning permission for a new development or construction project. In brief, the Arboricultural Impact Assessment or BS5837 Report typically includes the following information: A detailed description of the trees on the site, including their species, age, size, and health. An assessment of the condition of the trees and any potential risks they may pose to the development. BS5837 Quality or Retention Categories (defined as four categories A, B, C and U). The higher the quality the tree, the more of a constraint it presents to development. A measurement of the trees' perceived rooting area referred to as the root protection area (RPA) - a minimum rooting environment (area) that a tree needs to sustain itself. A calculation of the number of trees on the site and their overall value to the ecosystem. Recommendations for tree removal and retention along with the protection and preservation of the trees during the construction process, including measures to avoid damage to the RPAs.
-
How much does a BS5837 Tree Survey cost?The cost of a BS5837 tree survey can vary greatly depending on several factors, such as the size of the site, the number of trees present, and the complexity of the survey. Typically, for a small Site, the cost will be between £320 - 700. At ARB Innovators, we offer competitive pricing for our tree survey services. We recommend contacting us for a free quote, so we can provide you with an accurate estimate based on your specific needs.
-
Why is compliance with BS5837 essential?Compliance with BS5837 or BS5837:2012 is essential for those who are planning to undertake any kind of development project that involves trees. This British Standard provides guidance on the management of trees in relation to construction and development. It aims to ensure that trees are retained and properly protected during the development process, and that new trees are planted where necessary to compensate for any loss of existing trees. Compliance with BS5837 will not only help to protect the health and safety of the trees, but also ensure that the development is compliant with your local planning authorities (LPA) validation requirements, and ultimately, may be the difference between planning permission being granted or refused. Therefore, it is important to consult with an experienced arboricultural consultant like ARB Innovators who can provide expert advice and guidance on complying with this British Standard 5837.
-
Is a BS5837 Tree Survey a legal requirementA BS5837 Tree Survey is not a legal requirement, but it is often necessary when seeking planning permission for development projects that may impact trees, to meet local planning validation requirements. Even though it is not required by law, obtaining a BS5837 Tree Survey can streamline the planning process and ensure compliance with local regulations, ultimately saving time and potentially costly mistakes during development. Arb Innovators specialises in providing comprehensive BS5837 Tree Surveys that assess the impact of development on trees and offer recommendations for their protection.
-
What are the age categories for BS5837?When embarking on a development project, recognizing the age and value of the trees on your site is pivotal. The BS5837 Tree Survey categorises trees based on their age, among other factors, to ensure informed decisions are made regarding their retention or removal. Here's a breakdown of the age categories you'll encounter in a BS5837 Tree Survey: Young Trees: Typically under 10 years old, these trees are in the early stages of growth. They represent future potential and are often considered for retention to mature and enhance the site's ecological value. Semi-Mature Trees: Usually aged between 10 and 40 years, semi-mature trees have established themselves but have not yet reached their full size or ecological contribution. They are evaluated for their growth potential and impact on the development. Mature Trees: These trees, often aged 40 to 80 years, have reached their full size and provide significant ecological, aesthetic, and environmental benefits. Mature trees are highly valued in BS5837 surveys for their established presence and contribution to biodiversity. Veteran Trees: Trees of ecological, historical, cultural and landscape value. They are often prioritised for retention due to their irreplaceable nature and the unique habitats they provide. At ARB Innovators, we don't just assess the age of trees; we delve into their health, structural condition, and the role they play in your project's ecosystem. Our innovative approach, combining technology with arboricultural expertise, ensures that every tree is given the consideration it deserves, aligning your development with sustainable and environmentally conscious practices.
