Z analizo smeri in prostorske porazdelitve vrtač v okolici 22 izbranih jam na eogenem krasu na Floridi smo raziskovali povezavo med površinskim in podzemnim razvojem krasa. Primerjava smeri jamskih rovov in glavnih osi vrtač v okolici jam kaže na različno stopnjo povezave med njimi. Prostorsko porazdelitev vrtač smo raziskovali z orodji prostorske statistike v okolju ArcGIS, pri tem smo uporabili elipse standardnih odklonov centroidov vrtač in smeri osi vrtač, najbližjih sosedov izbranih jamskih rovov. Celotna analiza podatkov je pokazala tesno povezanost med nekaterimi jamami in okoliškimi vrtačami z vidika njihove orientacije in lege, kar kaže na pomen razpoklinskih sistemov za razvoj krasa.
