Scientists from Brno have been working on a unique project, mapping the changes of our landscape over the past century. In order to do so, they have been collecting old landscape paintings, which they subsequently compare to present-day photographs of the same place. For the past two years, scientists from the Institute of Geonics at the Czech Academy of Sciences have been searching for historical landscape paintings and photographs. After identifying the real locations depicted in the paintings, they travel to the place and take a new picture from exactly the same viewpoint. Petr Halas from the Institute of Geonics says the project was initiated by his late colleague, who got the idea as he travelled through the region on his work trips.
