Discovery of karst caves is mostly requires fieldwork. We wanted to find a more effective way of cave discovery. That is why we used LiDAR delivered digital elevation model and tested three spatial methods: topographical position index, local relief model and sky view factor. We choose five caves: Čehi 2, Najdena jama, Habečkov brezen, Kačna jama in Lipiška jama, which differ in location and morphometric features. Success of the methods was determined by comparing results visually, according to the location of Cadastre of caves and comparison between calculated area and estimated area of cave entrance.
