“3D sensing” can sound a bit… dry, right? But strip away the jargon, and it’s about capturing the world as it truly is.

Moving past flat images to real spatial data.

Professionals often struggle to choose the right 3D sensor.

Believe me, I get it. The sheer number of options is overwhelming.

Why should you care as a geospatial expert? Because 3D data adds a whole new dimension (literally!) to your work. It enables more precise analysis, better visualizations, and completely new applications.

Let me make sure that you know how various sensors work and which ones are right for you.

This isn’t just about tech; it’s about solving real problems. From smart city planning to environmental monitoring, 3D sensors can have a massive impact.

And you can start with your pocket buddy, i.e. your smartphone

🦊 Florent Poux, Ph.D.: Don’t be afraid to start small! Experimenting with basic 3D scanning apps on your phone is a great way to get a feel for the technology before diving into more complex setups.

Let’s demystify this.
