Aerial photogrammetry deals with the photos we can measure dimensions, determine the position of the object and carry out reconstruction of shapes. More precisely, we can create 3D model or orthophotomap, which is needed for working with maps and drawings.
The name of photogrammetry was composed of three Greek words photos - lightgramma - recordmetron - measure. Geodesy, geology, construction, archeology,… Drones have brought new possibilities to all these fields.

Benefits of photogrammetry

  • fast data update
  • high focus accuracy
  • real 2D or 3D model
  • cheaper solution


It is the most sought after and most used in aerial photogrammetry. It is basically an aerial image of the surface (map), which contains a coordinates. The orthophotomap finds the most use in geodesy, for example in design of landscaping and buildings. The infrastructure can change very quickly in some parts and updating images from the aircraft is very expensive. If a construction company, cadastral office or investor needs an up-to-date site map, they are drones fastest and cheapest solution.

3D model

Do you need to design a new shopping center? Or your dream house and want to see a realistic model set right in the area?

Create a 3D model using photogrammetry from a drone is very easy. I program the drone to the place of flight and then photograph the object from all possible angles. The more photos, the better the 3D model. I process the resulting photos in software that, according to the coordinates and data on the rotation of the camera, composes a cloud of points. That is not enough for the model alone. Next, we need to convert this cloud to a triangular network, which will create the resulting model.

The 3D model can be used by engineers to create realistic building designs ,interactive sights, natural attractions or maybe for 3D model printing.

Laser scanning (LiDAR)

It is currently the most advanced technology in obtaining surface data. The difference between classical photogrammetry and laser is that instead of photographs, distance is measured here. Because the laser can scan one place up to 5x, thus achieving much greater accuracy. We can thus determine the individual heights of trees and vegetation, various faults in the landscape, etc. Subsequently, we can graphically separate these individual heights or coat the resulting model with photographs, thus creating a more realistic 3D model.

Cubature calculations

The digital surface area model (DMT) allows us to measure the volume of objects very accurately. The great advantage of drone images and subsequent DMT is the accuracy, which is around approx 5 %. In the common method, the surveyor must focus on the entire object, which is very time consuming and the accuracy is around 20-30 %. With a drone, you can quickly measure the volume of soil and excavations, landfills or rubble, or find out how much material is in the quarry.

Other photogrammetry options:

  • map materials and plans
  • models of surface
  • 3D models
  • construction progress
  • surface exploration
  • documents for cadastral maps
  • roads and watercourses
  • landfills
  • laser scanning
  • volume of objects

What is price for photogrammetry with drone?

Every project is different. I make price individual, depending on the shooting length, technique used, distance, etc. You can find the approximate price in the price list.

Or you can write e-mail and say: Hi Jirka, please, I need 3D model - what is price?"
