DJI drones have revolutionized inspections thanks to their advanced technology and versatility. These systems can be equipped with different types of high-resolution sensors (primarily RGB and thermal), which allow for capturing highly detailed photos and videos of various elements.

Are you going to work on a large construction or excavation project? If so, you shouldn't forget an important step in this process: utility mapping. This involves identifying the exact location of all underground utility infrastructure, such as gas lines, water pipes, electrical lines, and communication lines, among others, to avoid accidentally damaging them in the process and prevent being responsible for a large and costly disaster.

Success story, where a project was executed integrating different geospatial capture techniques, using a DJI M350 drone with two sensors: Zenmuse P1 for photogrammetry and Zenmuse L2 for LiDAR. In this article, we will review the key points that made the use of both sensors necessary to provide a more representative and accurate capture of the area.

We invite you to this new Webinar developed by GEOCOM's UAS area, where we will explore photogrammetric fundamentals, experiences with DJI drones, and detail all the new features of Trimble Business Center Aerial Photogrammetry in its latest version.

In this experience, we immersed ourselves in the Trimble Reality Capture workflow to generate an "As-built" 3D model of a 5-story building with 2 underground levels.

Trimble has delved deeper into the PPP technique through Trimble RTX, which can be used either in real-time or post-processing. Now, in terms of compatibility, the questions that arise are: Is RTX compatible with determinations made in RTK? Can RTX and RTK data coexist in the same project?

Trigonometric leveling is a technique used in land surveying applications to determine elevation differences between two points using angular measurements and distances. Unlike geometric leveling, which determines elevation differences from staff readings, trigonometric leveling uses trigonometry to indirectly calculate the height difference.

In our recent mission, we completed a comprehensive photogrammetric flight experience, using cutting-edge technology to deliver high-precision, high-quality results. Here is an overview of our process ↓

GNSS in its RTK mode has become a standard for conducting topographic surveys due to its high productivity and ease of observation. Furthermore, by adding automatic drawing tools, the use of GNSS is tremendously beneficial.
