Why use photogrammetry for surveying and mapping?

Photogrammetry is a process involving the generation of precise measurements from photographs. However, in recent times, photogrammetry has evolved into a multipurpose technique that has been readily integrated into an array of modern applications.

Photogrammetry incorporates remote sensing and accelerated photography to create accurate measurements that are capable of processing 2-dimensional photographs into 3-dimensional models. This unique ability of photogrammetry has produced an intense level of interest from a large collective of businesses, software, programs, and individuals.

Concurrently, with the rapid rise in popularity of drones, photogrammetry has enjoyed a similar rise in consumer interest, with many buyers attracted by the advantages presented by the accessible photogrammetry use via increasingly affordable aerial drone aircraft. Let’s talk about the benefits of photogrammetry in surveying more.

Easy to use

The ongoing evolution of drone technology has transformed the photogrammetry industry by rendering it accessible for a wide variety of individuals and interests. Once relegated for use by highly trained professionals, photogrammetry is now a user-friendly process. With drones becoming more and more affordable, consumers are able to use them as a vehicle for their photogrammetry projects.

Simple equipment

Photogrammetry only requires users to have a digital SLR camera along with a compatible photogrammetric software.

Pixprocessing is a cutting-edge photogrammetric software targeted at solving various challenges of surveying and facilitating multiple on-site and off-site work stages. It offers innovative methods and provides the most efficient, sustainable and cost- effective surveying solutions.

If you have at least 3 photos taken from a different angle, you can already reconstruct the 3D model of the object with photogrammetric software. However, the more pictures, the more likely the 3D model will be realistic. The manual way to collect photographs is possible, but for better accuracy, one can use a drone. When photos dataset is available, it is uploaded to Pixprocessing software to generate the 3D model. Using the software, one can go from having a bunch of pictures to dense point clouds and terraformed DEM’s.

The 3D modeling process with Pixprocessing consists of 3 main steps that generate:

  • Sparse point cloud;
  • Dense point cloud;
  • DEM.

When one gets the 3D model, all the necessary analysis and calculations can be performed at a click.

Superior for ground surveying

Photogrammetry has experienced a significant evolution since its inception. Today it is a multi-functional process that is ideal for any application requiring high-resolution imagery of the utmost quality.

As we are specializing on the object reconstruction for the surveying industry, it is enough to have a most commonly used at least 12 MP camera, use 90-degree camera angulation and single grid track. In this way, you will save time and won’t harm the quality of the object reconstruction in a 3D mode.

Highly accurate

Photogrammetry is an accurate and economical solution. The drone market has a vast array of entry-level budget models that easily incorporate photogrammetry processes and provide high-resolution images for all manner of interests.


Photogrammetry is incredibly affordable. Conversely, a high-quality professional drone can be had for under along  €800 with a performance camera costing  €400 and below. Pixprocessing prime 3D modeling pack that lets you create realistic highly detailed 3D models is only for 171 Eur/month.

Evolved technology

Historically, photogrammetry was very unattainable due to its formerly common use on airplanes equipped with costly aerial cameras. In today’s modern times, professionals and small businesses are able to employ photogrammetry technology via drones and photogrammetric software solutions. The end result is easy to operate and affordable means to achieve the kind of precision surveying and mapping imagery that the only photogrammetry can provide.


Photogrammetry is technology that has existed for decades but has only become readily accessible to regular citizens. In contemporary times, the robust availability of photogrammetry has been heavily reliant upon the evolving drone market, featuring an array of professional and entry-level models that easily incorporate high-powered cameras for photogrammetry projects.

Completely versatile, and the optimal choice of those seeking a means to achieve surveying and mapping data, photogrammetric software is an integral part of daily lives of surveying industry.
