Deep Learning for Rapid Landslide Detection using Synthetic Aperture Radar (SAR) Datacubes

in

Well, let me explain it to you like I’m talking to my grandma who just got her first smartphone.

First off, “Deep Learning” is a fancy way of saying we’re using computers to learn from data and make predictions based on that learning. In this case, the computer is looking at SAR (Synthetic Aperture Radar) images to figure out if there are any landslides happening in an area.

Now, let me explain what a “SAR Datacube” is. Basically, it’s like a really fancy picture that has lots of layers or slices. Each slice represents a different time point or angle, and the computer can use all these images to create a 3D view of the area being monitored for landslides.

So, how does this “Deep Learning” thing work? Well, it’s kind of like teaching a baby bird to fly by showing them pictures of birds in flight and then letting them practice flapping their wings until they figure out how to do it themselves. Except instead of birds, we’re using SAR images to teach the computer what landslides look like.

The computer looks at lots of different SAR images that have been labeled as either “landslide” or “no landslide”. It then tries to identify patterns and features in those images that are common for both types of data, but also unique to each one. Once it has learned these patterns, the computer can use them to make predictions about whether a new SAR image shows a landslide or not.

This is really helpful because it allows us to quickly detect potential landslides before they become a major problem. And since we’re using synthetic data (which means we’re creating images that look like real ones, but aren’t actually from the real world), we can train our computer models without having to wait for actual landslide events to occur in nature.
