Drone Photogrammetry Basics

In recent years, drone photogrammetry has emerged as a powerful tool in the field of surveying and mapping. This technology allows us to create detailed 3D models and maps by capturing images from a drone and processing them using specialized software. In this blog post, we will explore the basics of drone photogrammetry, its applications, and its advantages.

What is Drone Photogrammetry?

Drone photogrammetry is the process of capturing images from a drone and using those images to create 3D models and maps. This process involves the use of specialized software to stitch together multiple images into a single, comprehensive model. The process is based on the principle of triangulation, where multiple overlapping images are used to calculate the precise location and orientation of objects in space.

Applications of Drone Photogrammetry

Drone photogrammetry has a wide range of applications in various industries. Some of the most common applications include:

Surveying and Mapping

Drone photogrammetry is widely used in the construction industry to create accurate maps and 3D models of construction sites. This information is used to plan and manage construction projects, monitor progress, and ensure compliance with building regulations.


Drone photogrammetry is used in the agriculture industry to monitor crop growth and health. By creating detailed maps of agricultural land, farmers can identify areas of their crops that require attention, such as irrigation or fertilization.


Drone photogrammetry is used in the mining industry to create detailed maps of mining sites. This information is used to plan and manage mining operations, monitor progress, and ensure compliance with environmental regulations.

Advantages of Drone Photogrammetry


Drone photogrammetry is a cost-effective alternative to traditional surveying methods. Drones can capture images of large areas quickly and efficiently, reducing the need for manual labor and expensive equipment.


Drone photogrammetry produces highly accurate maps and 3D models, with a level of detail that is not possible with traditional surveying methods.


Drone photogrammetry eliminates the need for workers to enter hazardous areas, such as construction sites or mining sites, reducing the risk of accidents.


Drone photogrammetry can quickly capture images of large areas, reducing the time required to complete a survey or mapping project.

Here is a brief summary of how we carry out drone photogrammetry:

  1. Use the right drone: We select a drone with a good camera and the capability to capture high-quality images. The drone should also have a stable flight performance and the ability to carry out autonomous flights.

  2. Plan the flight: We plan the flight path for the drone, including the altitude, speed, and camera settings. This can be done using drone flight planning software, such as DJI Ground Station Pro or Pix4D Capture.

  3. Fly the drone: We fly the drone along the pre-planned flight path, capturing images at regular intervals. We ensure to check the camera settings before starting the flight to ensure the images are captured correctly.

  4. Process the images: We use photogrammetry software, such as Agisoft Metashape or Pix4D Mapper, to process the images and create a 3D model or map. This software will use algorithms to analyze the images and stitch them together to create a 3D model or map.

  5. Analyze the data: Once the 3D model or map is created, it can be analyzed and used for various purposes, such as land surveying, construction planning, or environmental monitoring.

It is important to note that drone photogrammetry can be complex, and it is recommended that you use Drone Operators, like Carrot who have training and experience in carrying out drone photogrammetry projects.


Drone photogrammetry is a powerful tool that has revolutionized the field of surveying and mapping. With its cost-effectiveness, accuracy, safety, and time-saving benefits, drone photogrammetry is increasingly becoming the preferred method for mapping and surveying projects across a wide range of industries. As this technology continues to evolve, we can expect to see even more innovative applications and uses in the years to come.
