Point clouds - Everything you need to know

In this episode, we explore the world of point clouds — 3D data that is changing industries like construction, architecture, manufacturing, surveying, and archaeology. We begin by explaining what point clouds are and how they serve as detailed collections of data points that capture the shape and surface of real-world objects and environments.

We explore the different methods used to create point clouds, including laser scanning, LiDAR, photogrammetry, and the growing role of drones in data collection. You'll learn how these technologies differ, when to use each one, and how they impact the precision and usability of the data.

We also cover the many applications for point cloud technology: from creating accurate architectural models and mapping terrains, to assisting urban development and preserving historic sites.

You'll get valuable insights into data storage formats (like RCP, LAZ, PLY, XYZ) and factors that influence the time required to create point clouds — including project size, environment complexity, scanning technology, and software efficiency.

If you’ve ever been curious about how digital 3D environments are created from real-world spaces — or if you work in industries where precision mapping and modeling are crucial — this episode is packed with practical knowledge.
