Photogrammetry refers to the process of using overlapping photographs to create a map, drawing, or 3D model of a real world object or location.
Photogrammetry is perhaps the oldest form of visual surveying, with initial uses appearing alongside the advent of photography in the mid 19th century. Photogrammetry has evolved in tandem with technologies to both capture and analyze data, leading to its continued use and relevance as a method for developing 2D and 3D models.
Photogrammetry is best used where there is a need to capture the visual details of a site, as its key benefit is that it can be used to verify what is being seen. Photogrammetry’s visual capability provides a number of potential uses. From more traditional site survey and management applications, to its emerging use as a rapid deployment tool in disaster management and public safety - the use of photogrammetry is still evolving today.
However, Photogrammetry does have its drawbacks. While traditional aerial photogrammetry provides useful data, its usage is limited by the high cost of implementation. Conversely, terrestrial-based Photogrammetry relies on an operators photography skills and can place field staff in potentially harsh field conditions or unpredictable weather.
Thats where we come in. Our drone-based photogrammetry solution has the ability to capture incredible detail and use grid-photo capability to take multiple photos at a specified zoom level from a single vantage point. To put it simply, our drones excel at capturing data from a large area quickly, accurately, and affordably. Providing the same benefits as traditional methods, with a reduction in risk and cost.
Our team of technical experts work with clients to define, develop, and deliver tailored aerial services that directly meet the challenges of their business and industry.

Perhaps the most commonly seen application for Photogrammetry is its use as a tool for surveying, mapping, and modelling a site, object, or right of way.
Whether in the energy industry to determine right of way or site selection, the mining industry to map and model geospatial data, or the architecture and engineering world to render 3D models of buildings or infrastructure or conducting site inspections; Photogrammetry represents a tried and tested method to generate accurate and timely data to generate maps and models with survey grade accuracy.
Infrastructure asset inspection often requires a visual of areas that are inaccessible by foot, or are hazardous to reach by traditional means. Aerial Inspections using photogrammetry allow for real time visualization of an asset, or large scale data collection that can be uploaded and analyzed.
Whether examining transmission lines in the power industry to detect faults and failures, Conducting offshore inspections of oil and gas production facilities, or condition assessments of existing building or bridges; Photogrammetry provides a safe and accurate method to collect critical data for maintaining your assets.
Monitoring or managing wildlife is essential for keeping track of animal movement patterns, habitat utilization, and population demographics - but wildlife may live in an area that is inaccessible, present a potential safety risk to observers, or simply be difficult to encounter via terrestrial means.
Whether conducting baseline monitoring as the foundation of a projects Environmental Impact Assessment, trend monitoring as part of ongoing conservation efforts, or habitat monitoring to monitor the outcomes of forestry or development project; Photogrammetry provides a safe and unobtrusive means to measure and monitor wildlife effectively and accurately.
One of the emerging uses of Photogrammetry is as a tool for use in public safety and disaster management. When public safety is at risk, or a disaster occurs, first response teams need access to readily available, accurate information.
In recent years, Photogrammetry has been used as a tool in crime scene investigation and incident reconstruction - leveraging softwares like Pix4D to build visual models in 3D. Additionally response teams have seen value in photogrammetry as a tool for fire investigation, search and rescue, earthquake response, and more.
There are many potential applications for aerial photogrammetry in cultural heritage projects. Perhaps the most readily apparent is its use as a tool to survey, model, and preserve cultural sites and artifacts.
Blending key elements of mapping, modelling and asset inspections, drone-based photogrammetry in cultural heritage can help to capture, catalog, share information about sites around the world enabling experts to view true to life renderings and visualizations of historic sites, as well as the locations and artifacts within them.
Understanding the geology and underlying geotechnical structure of the earth is fundamental for economic, social, and environmental development. Acquiring geological data can be a costly, time-consuming, and often dangerous process.
From initial site investigations, to geological hazard assessments and site monitoring - photogrammetry is a frequently used tool to provide time-dependent data, over large and sometimes inaccessible or hazardous areas.
Traditional agriculture is practiced by performing tasks such as planting or harvesting against a predetermined schedule - but photogrammetry can help farmers make better decisions through the collection of real time data.
From using orthophoto data to determine relative biomass analysis, drought stress, irrigation scheduling, predict agricultural production, monitor nutrition, pests and diseases to using multispectral imaging to determine the optimal applications of seed and soil content; precision agriculture represents a relatively new approach that leverages photogrammetry’s technological toolset to adapt crop management strategies across the world.
Mining is an economically important component of our economy. Mined materials are needed to construct everyday goods and services that are critical to our way of life - from roads and hospitals, to automobiles and houses, computers and satellites, and the components needed to generate electricity.
From rapid stockpile volument assessments, to site monitoring of environmental effects, and blast planning - Photogrammetry has a wide range of applications across the mining industry owing to its rapid and accurate data collection.
