The Devil’s Town site is a unique geomorphological formation in southern Serbia, comprising over 200 earth structures. This site has been monitored using non-invasive techniques and a high-resolution point cloud was generated through photogrammetric imaging with an Unmanned Aerial Vehicle (UAV). In this study, automatic detection of the earth pyramids was performed using local maxima detection algorithm in order to create a digital inventory across different time epochs, enabling comparisons between past and present conditions of these geomorphological features. The results were compared with an official digital geomorphological inventory produced through manual mapping, achieving an overall accuracy (OA) exceeding 70%.
