Lately, you can read the term zombie fire in more and more media articles. A new way to gain views, or a real thing?

A guest blog post by Pierre Markuse

Zombie fires is a catchy name you can read in more and more articles and headlines in the media. With a reason, it attracts attention.

Now, before we begin to discuss whether zombie fire is a fitting name or more of an attraction-grabbing clickbait-naming we should take a look at what is usually described as a zombie fire.

It all begins with an initial wildfire. Important in this case is that for it to become what is sometimes called a zombie fire it has to start in, or spread into an underground peat…

A quick introduction into remote sensing for teachers who would like to use satellite images in class

A guest blog post by Pierre Markuse

Remote sensing is finding its way into more and more classrooms. Which is a good thing, as satellite images allow students to take a look with their own eyes and gain knowledge by actually seeing what otherwise would maybe just have been talked about in class.

A lot of media outlets are making ample use of those satellite images and data. …
