What’s the point?! Point characterization explained
What are the characteristics of a point and how can we calculate them? This is a short introduction to point characterization.

Is it a car? Is it a tree? Machine learning to the rescue!
Imagine this, a city is documented by millions of points acquired by an airborne laser scanner. Now, in order to make sense in all these points, we need to go one by one and classify it – does it belong to a tree? A building? A road? Here, we used a deep neural network to do the work for us!

The secrets of an important point
Each point cloud is composed of millions of points, how would we know which are the most important?
