In the world of engineering, drone photography helps to evaluate sites for construction, as well as create perspective images and 3D renderings. Engineers can produce images of project results or previews, as well as analyze their current progress.

Surveying is a profession that requires patience and accuracy. Companies across many industries ...

The ways that photogrammetry comes to life can vary widely by collection method, data gathered, industry use and compatible technologies.Some of the products that come from the process include orthomosaics, digital surface models and digital terrain models. An orthomosaic is essentially a birds-eye view of a terrain that adjusts for distortion and ...

This process can get complex, but it all comes down to the concept of triangulation. Triangulation involves taking pictures from a minimum of two different locations. These pictures create lines of sight that lead from each camera to specific points on the object being photographed. The intersection of these lines plays into mathematical calculations ...

Since aerial photogrammetry is one of the most common methods, let’s take a look at how those photos get classified.

Vertical photographs occur when the camera axis is vertical. So, if you put the camera in an airplane, its lens would point down to the ground for a birds-eye view. Tilted photographs uses oblique photos, in which you can see ...

Moving out to a larger scale, space-based photogrammetry occurs with cameras either fixed on Earth, in an artificial satellite or positioned on the moon or another planet. In fact, photogrammetry was touted as a key part of space exploration even in the ’60s, and technological advancements have made it even more relevant. It can tell us about cloud ...

Images in support of terrestrial photogrammetry techniques are usually taken from a fixed position on the ground with a camera’s axis parallel to the Earth. Data about the camera’s position, such as its coordinates, are collected at the time the photo is taken. Terrestrial photogrammetry for surveying typically requires fewer resources and skilled ...

The process of photogrammetry can vary, but the general idea revolves around gathering information about an object from photos of it. The photos are taken from different locations and angles to allow for precise calculations that help analysts gather the data they’re looking for. Typically, they use things like photo interpretation and geometric ...

For centuries, photogrammetry has played a critical role in our understanding of faraway objects and the Earth’s surface. It’s uses have expanded over the years and have led to a powerful range of game-changing technologies in industries like construction, engineering, medicine and much more. Photogrammetry gathers measurements and data about an ...
