To support the sustainable management and protection of karst water resources in the Liburnija region, Karsterra d.o.o. was commissioned by Liburnijske vode d.o.o. (now KD Vodovod i kanalizacija d.o.o., Podružnica Liburnijske vode) to develop a detailed cadastre of potential speleological features within the Kristal spring catchment area.

The project relied on high-resolution LiDAR data collected specifically for this purpose and applied advanced GIS analyses and remote sensing techniques to identify surface anomalies indicative of caves and pits. This geospatial approach enabled the detection of 396 potential speleological objects over a study area of nearly 40 km².

Ongoing field verification with the speleological association Estavela has already confirmed more than 200 entrances, of which more than a hundred have been explored and documented. This combination of cutting-edge geospatial technology and systematic fieldwork provides a robust scientific foundation for identifying additional water sources and ensuring the protection of sensitive karst aquifers critical for the public water supply.
