Drones for Photogrammetry


Photogrammetry is the science of making measurements from photographs. When combined with drone technology, it allows for the capture of spatial data in unprecedented detail, making it a powerful tool for various industries ranging from agriculture to construction to archaeology.

Why Drones?

  1. High-resolution imagery: Drones can fly at lower altitudes than traditional aircraft, allowing for the capture of high-resolution images.
  2. Cost-effective: Traditional aerial photogrammetry using manned aircraft can be expensive. Drones provide a more cost-effective solution, especially for smaller projects.
  3. Flexibility: Drones can be deployed quickly and can cover difficult-to-reach areas.

Popular Drones for Photogrammetry

  1. DJI Phantom 4 RTK: Known for its high-resolution camera and real-time kinematics (RTK) positioning capabilities, this drone is a favorite among professionals.
  2. senseFly eBee X: This fixed-wing drone is known for its long flight times and ability to cover large areas in a single flight.
  3. Parrot Anafi USA: With thermal imaging and 32x zoom, this drone is suitable for both photogrammetry and inspection tasks.

Software and Processing

Once images are captured, software like Pix4D, Agisoft Metashape, or OpenDroneMap can be used to stitch the images together, creating detailed 3D models or orthomosaic maps.


  1. Agriculture: Farmers use drone photogrammetry to monitor crop health, estimate yields, and identify areas that need attention.
  2. Construction: Detailed models of construction sites can be generated for planning, monitoring progress, and ensuring safety.
  3. Mining: Drones help in volume calculations, terrain modeling, and monitoring environmental impacts.
  4. Archaeology: Detailed site maps can be created without disturbing the site.
  5. Environmental monitoring: Monitoring changes in ecosystems, such as deforestation or coastal erosion.

Challenges and Considerations

  1. Weather: Drones used for photogrammetry require clear weather for best results.
  2. Flight regulations: Depending on the country, there might be restrictions on where and when drones can fly.
  3. Data management: Handling and processing large amounts of high-resolution imagery can be challenging and requires powerful computing resources.


Drones have revolutionized the field of photogrammetry, offering an efficient and cost-effective means of collecting detailed spatial data. As the technology continues to evolve, it’s likely that the applications and utility of best drone for photogrammetry will only expand.
