Photogrammetry transforms your aerial images into precise 3D models and digital maps. In 2025, drone professionals have a full range of specialized software at their disposal. Our guide introduces you to the best tools for converting your drone photos into usable data, whether you’re a beginner or an expert in aerial cartography.
Photogrammetry in a nutshell
Photogrammetry is a technique for extracting geometric information from images. It can be used to measure distances, surfaces or volumes, as well as to reconstruct three-dimensional models from photographs taken from different angles.
At the crossroads of photography and geometry, this method is based on a simple principle: when an object or piece of land is photographed from several viewpoints, it is possible, by calculation, to deduce its shape, size and position in space.
What are the three types of photogrammetry?
Aerial photogrammetry
This uses images taken from a drone, aircraft or satellite. Shots are generally nadiral (vertical to the ground), enabling large areas to be mapped and deliverables such as orthomosaics, digital terrain models (DTMs) or georeferenced 3D models to be produced. It is widely used in surveying, urban planning, precision agriculture and environmental management.
Terrestrial (or near-earth) photogrammetry
This method relies on images captured on the ground, using a camera or a camera mounted on a tripod or vehicle. It is ideal for surveys of facades, monuments, industrial or archaeological objects, where the level of detail required is very high. It is often used in architecture, heritage, engineering and inspection.
Oblique photogrammetry
Images are taken at an inclined angle rather than vertically. This type of photogrammetry is used to capture the sides and volumes of structures, such as buildings, cliffs or complex infrastructures. It enables more realistic 3D reconstruction, and is often combined with aerial photogrammetry to enhance models.
These three approaches can be used separately or in combination, depending on the technical objectives of the project and the type of surface or structure to be modeled.
How does photogrammetry work?
Photogrammetry is based on a mathematical process known as triangulation. By analyzing several images of the same object or location taken from different angles, specialized software identifies common points between the photos and calculates their relative position in space. The result is a three-dimensional reconstruction of the shapes observed.
The entire process generally follows three main stages:
- Acquisition of images with a good overlap between each photo, to ensure visual continuity.
- Automatic detection of homologous points (landmarks visible on several images) to establish geometric relationships.
- 3D calculation and reconstruction, to generate deliverables such as digital surface models, ortho-photos or maps.
What makes photogrammetry particularly interesting is its versatility, accuracy and ability to rapidly produce usable geometric data, all from simple images, without direct contact with the measured surfaces.
Why integrate photogrammetry software into your projects?
Integrating photogrammetry software into your projects represents real added value, both technically and strategically. Thanks to automated processing, it saves a considerable amount of time by rapidly generating professional deliverables, thus speeding up decision-making.
One of the main advantages is the accuracy of the results. Today’s software uses advanced algorithms capable of producing faithful reconstructions of the real environment, meeting the requirements of fields such as surveying, engineering, agriculture or worksite management. What’s more, these tools enable advanced visualization of data, in both 2D and 3D, facilitating interpretation and promoting better communication between technical teams, project managers and customers.
Software photogrammetry also stands out for its versatility. It can be used in many professional contexts, whether to monitor the evolution of a site, map a difficult-to-access area, document an architectural heritage or track material volumes in a mining or construction project.
By optimizing the collection and processing of spatial data, this software significantly reduces the costs associated with manual surveys, while limiting the risks associated with field interventions. Adopting a photogrammetry solution therefore means choosing a modern, precise and high-performance tool that integrates fully into demanding business processes, while reinforcing the reliability of decisions based on concrete, measurable data.
Which sectors use photogrammetry?
Photogrammetry is used in a wide range of professional sectors that require an accurate representation of space. For example:
In the field of surveying and cartography, it enables precise topographic surveys to be generated from aerial images, often captured by drone. This data is essential for land-use planning, urban planning and cadastral surveys.
Precision agriculture uses photogrammetry to monitor crop health, estimate yields or plan targeted interventions. The maps generated enable farmers to optimize resource use and improve productivity while reducing environmental impact.
In the construction and civil engineering sectors, it is used to document the progress of worksites, monitor the volumes of materials moved or produce digital terrain models for project design. It also facilitates feasibility studies and compliance monitoring.
Themining industry uses it to measure stocks, calculate volumes or monitor mining sites securely and without interrupting operations. Similarly, photogrammetry is used in natural resource and environmental management to assess erosion, monitor habitats and analyze the evolution of forest and coastal environments.
It is also present in archaeology and heritage modeling, where it enables the conservation and study of historical sites by modeling them in three dimensions with great fidelity. Finally, in the public safety and civil protection sectors, it is used to map disaster areas, plan emergency interventions or assess environmental risks.
Photogrammetry has thus become a key technology for all professionals who need precise, visual and usable spatial data in complex or large-scale contexts.

Photogrammetry by drone: our essential recommendations
To obtain quality results in drone photogrammetry, a few basic principles must be respected. It is advisable to capture all images in a relatively short space of time, to ensure consistency of lighting and shadows, while avoiding the presence of moving objects such as vehicles or people, which could adversely affect the quality of the reconstruction.
It is also preferable not to use the zoom when shooting. A fixed focal length ensures uniformity of dimension and perspective, which facilitates photogrammetric processing and improves the accuracy of the models generated.
Finally, it’s essential to vary the angles of view. By diversifying capture points – high up, sideways, obliquely – you increase the density of correspondences between images, enabling more accurate and faithful 3D reconstruction, especially in the case of complex or irregular structures.
By following these recommendations, you lay the foundations for optimized photogrammetric processing, whether for mapping, modeling or technical analysis of your data.

Frequently asked questions – FAQ
Which computer for photogrammetry?
For photogrammetry, it’s important to use a computer powerful enough to handle large volumes of images. A modern device, designed for professional software, will enable you to work faster and more efficiently. This avoids slowdowns during calculations and guarantees a better experience, whether for simple or complex projects.
What’s the difference between 3d scanning and photogrammetry?
Although both techniques can be used to create three-dimensional models of objects or surfaces, they operate differently. Photogrammetry relies on the analysis of several photographs taken from different angles to reconstruct a 3D scene using geometric calculations. It is widely used with drones for mapping, surveying and terrain modeling.
3D scanning, on the other hand, uses active sensors such as Lidar or structured light scanners to directly measure distances between the sensor and surfaces. This method is faster for capturing complex shapes with very high accuracy, even in low-light environments, but requires specialized equipment that is often more expensive.
In short, photogrammetry is more accessible and versatile, while 3D scanning offers greater precision and immediate results, particularly indoors or for highly detailed objects. The choice therefore depends on technical requirements and the context of use.
